THE DIAGNOSIS: Gouty Tophus

The lesion was excised and sent for histopathologic examination (eFigures 1 and 2), revealing aggregates of feathery, amorphous, pale-pink material, which confirmed the diagnosis of gouty tophus. The surgical site was left to heal by secondary intention. Upon further evaluation, the patient reported recurrent monoarticular joint pain in the ankles and feet, and laboratory workup revealed elevated serum uric acid. He was advised to follow up with his primary care physician to discuss systemic treatment options for gout.

Gout is an inflammatory arthritis characterized by the deposition of monosodium urate monohydrate crystals in the joints, soft tissue, and bone due to elevated serum uric acid. Uric acid is the final product of purine metabolism, and serum levels may be elevated due to excess production or underexcretion. Multiple genetic, environmental, and metabolic factors influence these processes.¹ Collections of monosodium urate crystals may develop intra- or extra-articularly, the latter of which are known as gouty tophi. These nodules have a classic chalklike consistency and typically are seen in patients with untreated gout starting approximately 10 years after the first flare. The most common locations for subcutaneous gouty tophi are acral sites (eg, fingertips, ears) as well as the wrists, knees, and elbows (olecranon bursae). Rarely, gouty panniculitis also may develop.²

Histopathology of gouty tophi reveals nodular aggregates of acellular, amorphous, pale-pink material surrounded by palisading histiocytes and multinucleated giant cells. The presence of needlelike monosodium urate crystals, which display negative birefringence, is diagnostic. Unfortunately, these crystals are destroyed in routine formalin processing.³

There are limited data regarding treatment of gouty tophi. Urate-lowering systemic medications such as pegloticase may be beneficial, but more data are needed.⁴ We pursued surgical excision in our case for definitive diagnosis; however, it is not a common treatment for gouty tophi. Typically, urate-lowering therapy is utilized to resolve or shrink lesions over time.⁵

The differential diagnosis for gouty tophi includes epidermal inclusion cyst (EIC), the most common type of cutaneous cyst. Though EICs can manifest anywhere on the body, they are not as common on the ears as gouty tophi. Epidermal inclusion cysts clinically manifest as soft subcutaneous nodules, and a central punctum often is noted. These lesions are derived from the follicular infundibulum and histologically are characterized by a cystic cavity lined by a stratified squamous epithelium with a granular layer. The cavity contains loose laminated keratin material.⁶

Pseudocyst of the auricle is a benign cystic swelling of the pinna that can develop spontaneously but most often manifests following trauma to the area, which is believed to separate the tissue planes in the cartilage, allowing fluid to accumulate. This lesion typically is asymptomatic, though some patients report mild tenderness.⁷ Histology shows a cystic structure within the cartilage without an epithelial lining, and a perivascular inflammatory response often is observed.⁸

Pilomatricoma, also known as pilomatrixoma, is a benign tumor derived from the hair follicle matrix that manifests as a firm, slow-growing, painless subcutaneous nodule. It most often is found on the head and neck, commonly in the periauricular area.⁹ Though rare, it has been found on the auricle and external auditory canal.¹⁰ Histologically, pilomatricomas are well-defined tumors containing internal trabeculae. They contain populations of basaloid and ghost cells and often calcify, sometimes with resultant bone formation.⁹

Dermoid cysts are benign tumors that develop along lines of embryonic closure and often are diagnosed at birth or in early childhood. They most commonly manifest on the head and neck, typically in the supraorbital area. Rarely, they have been reported on the ear.⁶ Dermoid cysts may resemble EICs clinically and histopathologically, except that the cyst wall contains mature adnexal structures such as hair follicles and sebaceous glands.

Hi, everyone. I’m Dr Kenny Lin. I am a family physician and associate director of the Lancaster General Hospital Family Medicine Residency, and I blog at Common Sense Family Doctor.

The receding of the pandemic and the understandable desire to return to normalcy has made COVID-19 vaccines a lower priority for many of our patients. However, family physicians should keep in mind that from October 1, 2024, to September 6, 2025, COVID-19 was responsible for an estimated 3.2 to 4.6 million outpatient visits, 360,000 to 520,000 hospitalizations, and 42,000 to 60,000 deaths.

In a previous commentary, I discussed the worsening disconnect between the evidence supporting the effectiveness and safety of vaccinations and increasing reluctance of patients and parents to receive them, fueled by misinformation from federal health agencies and the packing of the Advisory Committee on Immunization Practices (ACIP) with vaccine skeptics. Since then, Secretary of Health and Human Services (HHS), Robert F. Kennedy, Jr, has fired Dr Susan Monarez, his handpicked director of the CDC. This caused three senior CDC officials to resign in protest and precipitated further turmoil at the embattled agency. 

The FDA has approved 3 updated COVID-19 vaccines targeted to currently circulating strains: an mRNA vaccine from Moderna (Spikevax) for those aged 6 months or older; an mRNA vaccine from Pfizer/BioNTech (Comirnaty) for those aged ≥ 5 years; and a protein subunit vaccine from Novavax (Nuvaxovid) for those aged ≥ 12 years. However, approvals restricting the scope of these approvals to certain high-risk groups, combined with the ACIP’s recent decision to not explicitly recommend them for any group, have complicated access for many patients.

Medical groups, including the American Academy of Pediatrics (AAP), the American Academy of Family Physicians (AAFP), and the American College of Obstetricians and Gynecologists (ACOG), have published their own recommendations (Table). Of note, in opposition to the FDA and ACIP, the AAP and AAFP strongly recommend routine vaccination for children aged 6 to 23 months because they have the highest risk for hospitalization. The AAFP and ACOG both recommend COVID-19 vaccination in pregnancy to protect the pregnant patient and provide passive antibody protection to their infants up to 6 months of age. The Vaccine Integrity Project’s review of 12 safety studies published since June 2024 found that mRNA vaccines were not associated with increases in any adverse maternal or infant outcomes and had a possible protective effect against preterm birth.

In my previous commentary, 70% of Medscape readers indicated that they would follow vaccination recommendations from AAP even if they differed from CDC guidance. Administering vaccines outside of FDA labeling indications (i.e., “off label”) typically requires a physician’s prescription, which will almost certainly reduce COVID-19 vaccine uptake in children and pregnant patients, given that most people received these shots in pharmacies during the 2024-25 season. CVS and Walgreens, the country’s two largest pharmacy chains, are requiring physician prescriptions or waiting for ACIP guidance to make the new vaccines available in many states. However, an increasing number of states have implemented executive orders or passed legislation to permit pharmacists to provide vaccines to anyone who wants them. For example, the Pennsylvania State Board of Pharmacy voted unanimously to issue guidance that would allow pharmacists to administer any vaccines recommended by AAFP, AAP, or ACOG.

Erosion of vaccine uptake could easily worsen the burden of illness for our patients and the health system. Navigating the unnecessarily complex landscape of COVID-19 vaccines will be challenging, but it remains worthwhile.

As a hospitalist, you are in a unique position to notice changes in your hospitalized patients. This frontline perspective can be used to improve inpatient attention and care, and differs from primary care, where a clinician might only see a patient once or twice a year, and subtle, gradual changes may be missed, said George Cao, MD, MBA, a hospitalist at the University of Vermont Medical Center in Burlington and assistant professor at UVM’s Larner College of Medicine. 

But in the hospital, Cao said even small shifts — like becoming less active, eating less, or changes in personality — can become much more obvious. 

“As hospitalists…we see patients throughout the day, in different situations, and often end up spending more time with them over the course of a week than their primary care provider might in a year,” Cao explained. “This gives us a real advantage in picking up on subtle changes in mental awareness.”

These assessments can also be evaluated with the benefit of daily labs, frequent bedside interactions, and 24–hour observations.

With older adults, Cao said it’s important to go beyond just what’s in the chart. 

“I always start by reviewing notes from the primary care provider and previous admissions, but some of the most valuable insights come from talking with family and close friends to get a true sense of the patient’s baseline — how they usually think, move, and interact,” he said.

 

Why to Watch for Declining Mental Awareness

Declining mental awareness in the inpatient setting is often a sign of an underlying problem — whether that’s a reversible medical condition, unrecognized dementia, or the development of delirium, Cao said.

“On the inpatient side, I pay close attention to more than just memory loss,” he said. 

Changes in how patients function day–to–day, shifts in their behavior, or even something as simple as not wanting to get out of bed can be early signs of an aging mind or untreated psychiatric issues, he noted. 

“Of course, we always rule out infections and medication side effects, but I also look for other reversible causes like thyroid problems, electrolyte imbalances, low oxygen, pain, urinary retention, constipation, and nutritional deficiencies,” Cao said.

Of note, delirium is the most common cause of sudden mental status changes in the hospital, and “it’s easy to miss if you’re not looking for it.”

He summarized that classic signs are an acute and fluctuating course with changes in alertness, but added there are other red flags too: disorientation, hallucinations, changes in sleep patterns, sporadic unsafe behaviors, mood swings, and changes in activity level, whether that’s agitation or just being unusually quiet. 

By combining what he notices bedside and what is learned from the medical record (and from the people who know the patient best), Cao said he’s able to catch these changes early, identify the underlying cause, and work toward the best possible outcome. 

“One of the main interventions is providing mental stimulation,” he said.

 

Why Mental Stimulation Is So Vital 

Mental stimulation of the patient is critical to recovery and may prevent prolonged illness, said Meghana R. Medavaram, MD, associate director of consultation liaison and emergency psychiatry at Montefiore Medical Center’s Weiler Hospital in New York City. “Keeping a patient active both physically and mentally can help prevent deconditioning and risks of prolonged immobility,” she said.

It’s important to note that when patients are out of their familiar routines, away from their usual environment and people, and their sleep is fragmented, this can make them even more vulnerable. Keeping patients mentally stimulated during their hospital stay can help maintain their attention, orientation, and a healthy sleep-wake cycle — all things that are easily thrown off in the hospital, Cao said. 

“These disruptions hit the pathways that control attention, wakefulness, and the sleep–wake cycle. That’s when you see attention drifting, orientation fading, and circadian rhythms unraveling, especially at night, which is why “sundowning” is so common, Cao said, referring to the syndrome where older adults or people with dementia experience behavioral changes in late afternoon or evening. “Mental stimulation is critical in the hospital because when the brain isn’t active and gets disoriented, it becomes an easy target for delirium.” 

He said delirium often develops in older adults when acute stressors like inflammation, low oxygen, metabolic imbalances, or sedating medications disrupt the brain’s arousal systems and networks, especially in older adults.

Therefore, Cao said, encourage your patients to be more engaged during the day through conversation, activities, or regular reorientation. “This supports the brain networks that help prevent inattention and confusion, which are the hallmarks of delirium. Daytime stimulation also helps build up the natural drive for nighttime sleep, so patients are less likely to nap during the day and be awake and disoriented at night.”

To support this, it’s helpful to schedule medications during waking hours instead of around–the–clock dosing that interrupts sleep, and to cluster nighttime care activities to minimize disturbances, Cao explained. Ensuring patients have their glasses, hearing aids, and familiar routines, along with encouraging mobility and hydration, further protects against delirium and supports patients’ cognitive health during hospitalization. “These same principles are just as important in outpatient subacute rehab settings and at home, so it’s essential to take home these strategies after discharge,” he said.

 

A Family Member or Friend May Help

Hospitalists can suggest straightforward ways to encourage families and friends to keep patients engaged during a hospital stay. Visits and chats can go a long way as conversations are incredibly grounding, Cao said. Other methods could be bringing in favorite foods or snacks, a phone chat or video call, or even showing prerecorded video messages. “These can be effective. Patients respond well to seeing and hearing familiar faces and voices, even if it’s just on a screen,” Cao said.

Beyond that, he said, activities such as watching and discussing the news, reading aloud, using tablets for games, watching movies, doing crossword puzzles, knitting, reminiscing, and playing word games can also be mentally stimulating for patients. 

In addition, safe exercises/activities that patients can do in bed — with advice from physical therapy and occupational therapy — are beneficial, Medavaram said. “These often include gentle range–of-motion activities,” she said. 

 

Share Importance of Mental Stimulation With Patients and Caregivers

If a hospitalist wants to motivate patients to keep their minds active, the framing should be simple, positive, and tied directly to their goals of getting better and getting home, said Medavaram. She provided this script suggestion:

“One of the best ways to help your recovery isn’t just taking your medicine, it’s keeping your mind active. When you’re in the hospital, it’s easy to spend the day lying in bed and staring at the TV in your room, but that can make your brain slow down and even cause confusion. Simple things — like reading, talking with visitors, doing puzzles, listening to music you enjoy, or telling a nurse about your favorite memories — can keep your brain sharp. Staying mentally active helps your thinking stay clear and can even help you get home sooner. Think of it like physical therapy for your brain.”

To support this, it’s helpful to schedule medications during waking hours instead of around–the–clock dosing that interrupts sleep, and to cluster nighttime care activities to minimize disturbances, Cao explained. Ensuring patients have their glasses, hearing aids, and familiar routines, along with encouraging mobility and hydration, further protects against delirium and supports patients’ cognitive health during hospitalization. “These same principles are just as important in outpatient subacute rehab settings and at home, so it’s essential to take home these strategies after discharge,” he said.

 

A Family Member or Friend May Help

Hospitalists can suggest straightforward ways to encourage families and friends to keep patients engaged during a hospital stay. Visits and chats can go a long way as conversations are incredibly grounding, Cao said. Other methods could be bringing in favorite foods or snacks, a phone chat or video call, or even showing prerecorded video messages. “These can be effective. Patients respond well to seeing and hearing familiar faces and voices, even if it’s just on a screen,” Cao said.

Beyond that, he said, activities such as watching and discussing the news, reading aloud, using tablets for games, watching movies, doing crossword puzzles, knitting, reminiscing, and playing word games can also be mentally stimulating for patients. 

In addition, safe exercises/activities that patients can do in bed — with advice from physical therapy and occupational therapy — are beneficial, Medavaram said. “These often include gentle range–of-motion activities,” she said. 

 

Share Importance of Mental Stimulation With Patients and Caregivers

If a hospitalist wants to motivate patients to keep their minds active, the framing should be simple, positive, and tied directly to their goals of getting better and getting home, said Medavaram. She provided this script suggestion:

“One of the best ways to help your recovery isn’t just taking your medicine, it’s keeping your mind active. When you’re in the hospital, it’s easy to spend the day lying in bed and staring at the TV in your room, but that can make your brain slow down and even cause confusion. Simple things — like reading, talking with visitors, doing puzzles, listening to music you enjoy, or telling a nurse about your favorite memories — can keep your brain sharp. Staying mentally active helps your thinking stay clear and can even help you get home sooner. Think of it like physical therapy for your brain.”

As a hospitalist, you are in a unique position to notice changes in your hospitalized patients. This frontline perspective can be used to improve inpatient attention and care, and differs from primary care, where a clinician might only see a patient once or twice a year, and subtle, gradual changes may be missed, said George Cao, MD, MBA, a hospitalist at the University of Vermont Medical Center in Burlington and assistant professor at UVM’s Larner College of Medicine. 

But in the hospital, Cao said even small shifts — like becoming less active, eating less, or changes in personality — can become much more obvious. 

“As hospitalists…we see patients throughout the day, in different situations, and often end up spending more time with them over the course of a week than their primary care provider might in a year,” Cao explained. “This gives us a real advantage in picking up on subtle changes in mental awareness.”

These assessments can also be evaluated with the benefit of daily labs, frequent bedside interactions, and 24–hour observations.

With older adults, Cao said it’s important to go beyond just what’s in the chart. 

“I always start by reviewing notes from the primary care provider and previous admissions, but some of the most valuable insights come from talking with family and close friends to get a true sense of the patient’s baseline — how they usually think, move, and interact,” he said.

 

Why to Watch for Declining Mental Awareness

Declining mental awareness in the inpatient setting is often a sign of an underlying problem — whether that’s a reversible medical condition, unrecognized dementia, or the development of delirium, Cao said.

“On the inpatient side, I pay close attention to more than just memory loss,” he said. 

Changes in how patients function day–to–day, shifts in their behavior, or even something as simple as not wanting to get out of bed can be early signs of an aging mind or untreated psychiatric issues, he noted. 

“Of course, we always rule out infections and medication side effects, but I also look for other reversible causes like thyroid problems, electrolyte imbalances, low oxygen, pain, urinary retention, constipation, and nutritional deficiencies,” Cao said.

Of note, delirium is the most common cause of sudden mental status changes in the hospital, and “it’s easy to miss if you’re not looking for it.”

He summarized that classic signs are an acute and fluctuating course with changes in alertness, but added there are other red flags too: disorientation, hallucinations, changes in sleep patterns, sporadic unsafe behaviors, mood swings, and changes in activity level, whether that’s agitation or just being unusually quiet. 

By combining what he notices bedside and what is learned from the medical record (and from the people who know the patient best), Cao said he’s able to catch these changes early, identify the underlying cause, and work toward the best possible outcome. 

“One of the main interventions is providing mental stimulation,” he said.

 

Why Mental Stimulation Is So Vital 

Mental stimulation of the patient is critical to recovery and may prevent prolonged illness, said Meghana R. Medavaram, MD, associate director of consultation liaison and emergency psychiatry at Montefiore Medical Center’s Weiler Hospital in New York City. “Keeping a patient active both physically and mentally can help prevent deconditioning and risks of prolonged immobility,” she said.

It’s important to note that when patients are out of their familiar routines, away from their usual environment and people, and their sleep is fragmented, this can make them even more vulnerable. Keeping patients mentally stimulated during their hospital stay can help maintain their attention, orientation, and a healthy sleep-wake cycle — all things that are easily thrown off in the hospital, Cao said. 

“These disruptions hit the pathways that control attention, wakefulness, and the sleep–wake cycle. That’s when you see attention drifting, orientation fading, and circadian rhythms unraveling, especially at night, which is why “sundowning” is so common, Cao said, referring to the syndrome where older adults or people with dementia experience behavioral changes in late afternoon or evening. “Mental stimulation is critical in the hospital because when the brain isn’t active and gets disoriented, it becomes an easy target for delirium.” 

He said delirium often develops in older adults when acute stressors like inflammation, low oxygen, metabolic imbalances, or sedating medications disrupt the brain’s arousal systems and networks, especially in older adults.

Therefore, Cao said, encourage your patients to be more engaged during the day through conversation, activities, or regular reorientation. “This supports the brain networks that help prevent inattention and confusion, which are the hallmarks of delirium. Daytime stimulation also helps build up the natural drive for nighttime sleep, so patients are less likely to nap during the day and be awake and disoriented at night.”

To support this, it’s helpful to schedule medications during waking hours instead of around–the–clock dosing that interrupts sleep, and to cluster nighttime care activities to minimize disturbances, Cao explained.

For many years, topical treatment of plaque psoriasis was limited to steroids, calcineurin inhibitors, vitamin D analogs, retinoids, coal tar products, and anthralin. In recent years, 2 new nonsteroidal treatment options with alternative mechanisms of action, roflumilast 0.3% and tapinarof 1%, have been approved by the US Food and Drug Administration.¹ Roflumilast 0.3%, a topical phosphodiesterase 4 inhibitor, was shown in phase 3 clinical trials to reach an Investigator Global Assessment response of 37.5% to 42.2% in 8 weeks using once-daily application with minimal cutaneous adverse effects.¹ Furthermore, it has demonstrated efficacy in treating psoriasis in intertriginous areas in subset analyses.¹ Tapinarof is an aryl hydrocarbon receptor agonist that suppresses Th17 cell differentiation by downregulating IL-17, IL-22, and IL-23.¹ In phase 3 clinical trials, 35% to 40% of patients who used tapinarof cream 1% once daily demonstrated improvement in psoriasis compared with 6% who used the vehicle alone.² In these studies, 18% to 24% of patients who used tapinarof cream 1% experienced folliculitis.²

Acute generalized exanthematous pustulosis (AGEP) is a nonfollicular pustular drug reaction with systemic symptoms that typically occurs within 2 weeks of exposure to an inciting medication. Systemic antibiotics are the most commonly reported cause of AGEP.³ There are few reports in the literature of AGEP induced by topical agents.^4,5 We report a case of AGEP in a young man following the use of tapinarof cream 1%.

A 23-year-old man with a history of psoriasis presented to the emergency department with fever and a pustular rash. One week prior to presentation, he developed a pustular eruption around plaques of psoriasis on the arms and legs. The patient had been prescribed tapinarof cream 1% by an outside dermatologist and was applying the medication to the affected areas once daily for 1 month prior to onset of symptoms. He discontinued tapinarof a few days prior to the eruption starting, but the rash progressed centrifugally and was associated with fevers and fatigue despite treatment with a brief course of empiric cephalexin prescribed by his primary care provider.

At presentation to our institution, the patient had widespread erythematous patches studded with pustules located on the arms, legs, and flexural areas as well as plaques of psoriasis involving approximately 20% of the body surface area (Figure 1). Furthermore, the patient was noted to have large noninflammatory bullae along the legs. The new eruption occurred on areas that were both treated and spared from the tapinarof cream 1%. Laboratory evaluation showed neutrophil-­predominant leukocytosis (white blood cell count, 15.9×10³/µL ­[reference range, 4.0-11.0×10³/µL]; absolute neutrophil count, 10.3×10³/µL [reference range, 1.5-8.0×10³/µL]), absolute eosinophilia (1930/µL [reference range, 0-0.5×10³/µL]), hypocalcemia (8.4 mg/dL ­[reference range, 8.5-10.5 mg/dL]), and a mild transaminitis ­(aspartate aminotransferase, 37 IU/L [reference range, 10-40 IU/L]; alanine aminotransferase, 53 IU/L ­[reference range, 7-56 U/L]). Histopathology demonstrated spongiosis with subcorneal and intraepidermal pustules and mixed dermal inflammation containing eosinophils (Figure 2). Direct immunofluorescence revealed mild granular staining of C3 at the basement membrane zone.

The patient was started on 1 mg/kg/d of prednisone tapered over 20 days, and he rapidly improved. Alanine aminotransferase levels peaked at 120 IU/L 2 weeks later. At that time, he had complete resolution of the original eruption and was transitioned to topical steroids for continued management of the psoriasis (Figure 3).

The differential diagnosis for our patient included AGEP, generalized pustular psoriasis (GPP), miliaria pustulosa, generalized cutaneous candidiasis, exuberant allergic contact dermatitis (ACD), and linear IgA bullous dermatosis (LABD). Based on the clinical manifestations, laboratory results, and histopathologic evaluation, we made the diagnosis of AGEP secondary to tapinarof with systemic absorption. Acute generalized exanthematous pustulosis has been reported with topical use of morphine and diphenhydramine, among other agents.^4,5 To our knowledge, AGEP due to tapinarof cream 1% has not been reported. In the original clinical trials of tapinarof, folliculitis was contained to sites of application.² Our patient developed pustules at sites distant to areas of application, as well as systemic symptoms and laboratory abnormalities, indicating a systemic reaction. It can be difficult to distinguish AGEP clinically and histologically from GPP. Both conditions can manifest with fever, hypocalcemia, and sterile pustules on a background of erythema that favors intertriginous areas.⁶ Infection, rapid oral steroid withdrawal, pregnancy, and rarely oral medications have been reported causes of GPP.⁶ Our patient did not have any of these exposures. There is overlap in the histology of AGEP and GPP. One retrospective series compared histologic samples to help distinguish these 2 entities. Reliable markers that favored AGEP over GPP included eosinophilic spongiosis, interface dermatitis, and dermal eosinophilia (>2/mm²).⁷ In contrast, the presence of CD161 positivity in the dermis with at least 10 cells favored a diagnosis of GPP.⁷ In our case, the presence of spongiosis with eosinophils in the dermis favored a diagnosis of AGEP over GPP. 

Miliaria pustulosa is a benign condition caused by the occlusion of the epidermal portion of eccrine glands related to either high fever or hot and humid environmental conditions. While it can be present in intertriginous areas like AGEP, miliaria pustulosa can be seen extensively on the back, most commonly in immobile hospitalized patients.⁸ Generalized cutaneous candidiasis usually is caused by the yeast Candida albicans and can take on multiple morphologies, including folliculitis.⁹ The eruption may be disseminated but often is accentuated in intertriginous areas and the anogenital folds. Predisposing factors include immunosuppression, endocrinopathies, recent use of systemic antibiotics or steroids, chemotherapy, and indwelling catheters.⁹ Outside of recent antibiotic use, our patient did not have any risk factors for miliaria pustulosa, making this diagnosis unlikely.

Given the presence of overlapping bullae along the lower extremities, an exuberant ACD and LABD were considered. Bullae formation can occur in ACD secondary to robust inflammation and edema leading to acantholysis.¹⁰ While a delayed hypersensitivity reaction to topical tapinarof cream 1% was considered given that the patient used the medication for approximately 1 month prior to the onset of symptoms, it would be unlikely for ACD to present with a concomitant pustular eruption. Linear IgA bullous dermatosis is an autoimmune blistering disease in which antibodies target bullous pemphigoid antigen 2, and there is characteristically linear deposition of IgA at the dermal-epidermal junction that leads to subepidermal blistering.¹¹ This often manifests clinically as widespread tense vesicles in an annular or string-of-pearls appearance. However, morphologies can vary, and large bullae may be seen. In adults, LABD typically is associated with inflammatory bowel disease, malignancy, or medications, notably vancomycin.^11,12 Our patient did not have any of these predisposing factors, and his biopsy for direct immunofluorescence did not reveal the classic pattern described above.

Interestingly, there have been reports in the literature of bullous AGEP in the setting of oral anti-infectives. One report described a 62-year-old woman who developed widespread nonfollicular pustules with multiple tense serous blisters 24 hours after taking oral terbinafine.¹³ Another case described an 80-year-old woman with a similar presentation following a course of ciprofloxacin (although the timeline of medication administration was not described).¹⁴ In this case, patch testing to the culprit medication reproduced the response.¹⁴ In both cases, a biopsy revealed subcorneal and intraepidermal pustules with marked dermal edema.^13,14 As previously described, spongiosis is a common feature of AGEP. We hypothesize that, similar to these reports, our patient had a robust inflammatory response leading to spongiosis, acantholysis, and blister formation secondary to AGEP.

Dermatologists should be aware of this case of AGEP secondary to tapinarof cream 1%, as reports in the literature are rare and it is a reminder that topical medications can cause serious systemic reactions.

Dermatologists should be aware of this case of AGEP secondary to tapinarof cream 1%, as reports in the literature are rare and it is a reminder that topical medications can cause serious systemic reactions.

Last month, I had the privilege of joining more than one hundred physician colleagues in Washington, DC, for AGA Advocacy Day. While standing amidst the majesty of the Capital, I found myself deeply appreciative for those who dedicate their time and energy to public service. Many of these dedicated federal workers choose to be in DC because of a sincere belief in their mission.

Among these mission-driven public servants are federal employees who work in the Department of Veterans Affairs (VA). As a member of this group, I come to work energized by the mission to care for those who have served in our military. In my clinical practice, I am reminded regularly of the sacrifices of veterans and their families. This month, and especially on Veterans Day, I hope we will take a moment to express gratitude to veterans for their service to our country.

This month is also a timely opportunity to recognize the immense contributions of VA physicians to the field of gastroenterology. Many young gastroenterologists may not know that it was the landmark VA Cooperative Study #380, led by Dr. David Lieberman (Portland VA) that helped push Medicare to cover reimbursement for screening colonoscopy. Today, one of the most important ongoing studies in our field – VA Cooperative Study #577 – continues the VA tradition of high-impact health services research. Launched in 2012, the study has enrolled 50,000 veterans to compare FIT and colonoscopy. It is led by Dr. Jason Dominitz (Seattle VA) and Dr. Doug Robertson (White River Junction VA). 

Beyond research, VA gastroenterologists play a critical role in training the next generation of clinicians. Over 700 gastroenterologists count the VA as a clinical home, making it the largest GI group practice in the country. Many of us — myself included — were trained or mentored by VA physicians whose dedication to service and science has shaped our careers and the field at large.

This month’s issue of GI & Hepatology News has stories about other important contributions to our field. The stories and perspective pieces on Artificial Intelligence are particularly poignant given the announcement last month on the awarding of the Nobel Prize in economics to researchers who study “creative destruction,” the way in which one technological innovation renders others obsolete. Perhaps this award offers another reason to reemphasize and embrace the “art” of medicine.

The views expressed here are my own and do not necessarily reflect the official policy or position of the U.S. Department of Veterans Affairs or the United States Government.

The requisites of government are that there be sufficiency of food, sufficiency of military equipment, and the confidence of the people in their ruler.

Analects by Confucius¹

From ancient festivals to modern holidays, autumn has long been associated with the gathering of the harvest. Friends and families come together around tables laden with delicious food to enjoy the pleasures of peace and plenty. During these celebrations, we must never forget that without the strength of the nation’s military and the service of its veterans, this freedom and abundance would not be possible. Our debt of gratitude to the current and former members of the armed services makes the fact that a substantial minority experiences food insecurity not only a human tragedy, but a travesty of the nation’s promise to support those who wear or have worn the uniform.

The National Defense Authorization Act for Fiscal Year 2020 charged the Secretary of Defense to investigate food insecurity among active-duty service members and their dependents.² The RAND Corporation conducted the assessment and, based on the results of its analysis, made recommendations to reduce hunger among armed forces members and their families.³

The RAND study found that 10% of active-duty military met US Department of Agriculture (USDA) criteria for very low food security; another 15% were classified as having low food security. The USDA defines food insecurity with hunger as “reports of multiple indications of disrupted eating patterns and reduced food intake.” USDA defines low food security as “reports of reduced quality, variety, or desirability of diet. Little or no indication of reduced food intake.”⁴

As someone who grew up on an Army base with the commissary a short trip from military housing, I was unpleasantly surprised that food insecurity was more common among in-service members living on post. I was even more dismayed to read that a variety of factors constrained 14% of active-duty military experiencing food insecurity to seek public assistance to feed themselves and their families. As with so many health care and social services, (eg, mental health care), those wearing the uniform were concerned that participating in a food assistance program would damage their career or stigmatize them. Others did not seek help, perhaps because they believed they were not eligible, and in many cases were correct: they did not qualify for food banks or food stamps due to receiving other benefits. A variety of factors contribute to periods of food insecurity among military families, including remote or rural bases that lack access to grocery stores or jobs for partners or other family members, and low base military pay.⁵

Food insecurity is an even more serious concern among veterans who are frequently older and have more comorbidities, often leading to unemployment and homelessness. Feeding America, the nation’s largest organization of community food banks, estimates that 1 in 9 working-age veterans are food insecure.⁵ US Department of Veterans Affairs (VA) statistics indicate that veterans are 7% more likely to experience food insecurity than other sectors of the population.⁶ The Veterans Health Administration has recognized that food insecurity is directly related to medical problems already common among veterans, including diabetes, obesity, and depression. Women and minority veterans are the most at risk of food insecurity.⁷

Recognizing that many veterans are at risk of food insecurity, the US Department of Defense and VA have taken steps to try and reduce hunger among those who serve. In response to the shocking statistic that food insecurity was found in 27% of Iraq and Afghanistan veterans, the VA and Rockefeller Foundation are partnering on the Food as Medicine initiative to improve veteran nutrition as a means of improving nutrition-related health consequences of food insecurity.⁸

Like many federal practitioners, I was unaware of the food insecurity assistance available to active-duty service members or veterans, or how to help individuals access it. In addition to the resources outlined in the Table, there are many community-based options open to anyone, including veterans and service members. 

I have written columns on many difficult issues in my years as the Editor-in-Chief of Federal Practitioner, but personally this is one of the most distressing editorials I have ever published. That individuals dedicated to defending our rights and protecting our safety should be compelled to go hungry or not know if they have enough money at the end of the month to buy food is manifestly unjust. It is challenging when faced with such a large-scale injustice to think we cannot make a difference, but that resignation or abdication only magnifies this inequity. I have a friend who kept giving back even after they retired from federal service: they volunteered at a community garden and brought produce to the local food bank and helped distribute it. That may seem too much for those still working yet almost anyone can pick up a few items on their weekly shopping trip and donate them to a food drive. 

As we approach Veterans Day, let’s not just express our gratitude to our military and veterans in words but in deeds like feeding the hungry and urging elected representatives to fulfill their commitment to ensure that service members and veterans and their families do not experience food insecurity. Confucian wisdom written in a very distant time and vastly dissimilar context still rings true: there are direct and critical links between food and trust and between hunger and the military.¹

Necrobiotic xanthogranuloma (NXG) is classified as a cutaneous non–Langerhans cell histiocytosis, often seen with monoclonal gammopathy of undetermined significance or multiple myeloma.¹ Clinically, it appears as a red or yellow plaque with occasional ulceration and telangiectasias, most commonly seen periorbitally and on the trunk. On pathology, NXG appears as necrobiosis, giant cells, and various inflammatory cells extending into the subcutaneous tissue.² In this article, we describe a rare presentation of NXG in location and skin type.

A 52-year-old woman with a history of systemic lupus erythematosus (SLE) presented with alopecia and a tender lesion on the scalp of 5 years’ duration (Figure 1). The patient had no history of a similar lesion, and no other lesions were present. A biopsy performed at an outside clinic a few weeks to months prior to the initial presentation to our clinic showed NXG (Figure 2). Evaluation at our clinic revealed a 4x4-cm orange-brown annular plaque on the left parietal scalp. Serum and urine protein electrophoresis studies were negative. The patient reported she was up to date with recommended screenings such as mammography and colonoscopy. 

We started the patient on topical triamcinolone and topical ruxolitinib and administered intralesional triamcinolone. She was already taking hydroxychloroquine and leflunomide for SLE. Three weeks later, she returned with improved symptoms and appearance (Figure 1). She remained on intralesional triamcinolone and ruxolitinib and continues to experience improvement.

Necrobiotic xanthogranuloma is rare and typically is associated with monoclonal gammopathy.² In one study, 83 of 100 of patients with NXG presented with or were found to have a monoclonal gammopathy.² In another study, paraproteinemia was detected in 82.1% of patients.³ The majority of case reports and systematic reviews detail periorbital or thoracic lesions.⁴ The location on the scalp and lack of association with paraproteinemia make this a rare presentation of NXG. Studies may be warranted to explore any association of SLE with NXG if more cases present.

In a multicenter cross-sectional study and systematic review of 235 patients with NXG, 87% were White, 12% were Asian, and only 1% were Black or African American.³ The limited representation of skin of color raises concern for the possibility of missed diagnoses and delays in care. 

Treatment of NXG often is multimodal with use of intravenous immunoglobulin, oral steroids, chlorambucil, melphalan, and other alkylating agents, and response is variable.^3-6 Recent studies show treatment effectiveness with Janus kinase inhibitors in granulomatous dermatitides.^7-9 As our patient was not responding to prior treatments, we decided to try ruxolitinib, and she has continued to improve with it.^10,11 Interestingly, the patient experienced continued improvement with intralesional triamcinolone, which is not often reported in the literature.^2-6 Overall, NXG is an extremely rare condition that requires special care in workup to rule out paraproteinemia and a thoughtful approach to treatment modalities.

TOPLINE:

Racial and ethnic discrimination was consistently associated with increased risk for psychosis in studies included in a new umbrella review, with odds nearly doubled for both psychotic symptoms and experiences.

METHODOLOGY:

• Researchers searched 5 databases and then conducted an umbrella review of 7 systematic reviews, 4 of which included meta-analyses, published between 2003 and 2023.
• The systematic reviews included 23 primary studies representing more than 40,000 participants from Europe and the US.
• Investigators assessed the potential association between perceived racial or ethnic discrimination (mostly measured using self-reported questionnaires) and risk for psychosis (measured using established questionnaires).
• They assessed the risk for bias using the 16-item A MeaSurement Tool to Assess systematic Reviews, version 2 (AMSTAR-2) checklist.

TAKEAWAY:

• All reviews that included meta-analyses showed significant associations between perceived ethnic discrimination and psychotic symptoms (adjusted odds ratio [aOR], 1.78; 95% CI, 1.3-2.5) and psychotic experiences (pooled OR, 1.9; 95% CI, 1.4-2.7).
• Perceived racial or ethnic discrimination was also strongly linked to delusional symptoms (OR, 2.5; 95% CI, 1.6-4.0) and hallucinatory symptoms (OR, 1.65; 95% CI, 1.3-2.1).
• The largest of the included studies showed a dose-response relationship between higher levels of lifetime perceived racial or ethnic discrimination and greater likelihood of psychotic experiences.
• More robust associations were found in nonclinical populations compared to clinical ones, but there were significant associations in both.

IN PRACTICE:

“Our review was only looking at the impact of a person directly perceiving racism or interpersonal racial or ethnic discrimination; it may be that systemic racism, which can go unseen but still have profound impacts, could further contribute to mental health disparities,” lead investigator India Francis-Crossley, University College London, London, UK, said in a press release.

SOURCE:

The study was published online in PLOS Mental Health. 

LIMITATIONS:

The evidence was primarily based on cross-sectional studies and was limited by high heterogeneity. The reviews included showed low or critically low AMSTAR-2 quality scores, which may have affected the robustness of the findings. More robust evidence was observed for psychotic outcomes in nonclinical populations compared to clinical samples. Additionally, the study potentially exacerbated errors or misreporting in the original reviews and did not include relevant structural factors such as income, education, housing, and poverty.

DISCLOSURES:

The study was funded by the University College London-Windsor Fellowship Research Opportunities scholarship, Wellcome Trust PhD Fellowship in Mental Health Science, Mental Health Mission Early Psychosis Workstream, and UK Research and Innovation funding for the Population Mental Health Consortium. The investigators reported having no relevant conflicts of interest.

• They assessed the risk for bias using the 16-item A MeaSurement Tool to Assess systematic Reviews, version 2 (AMSTAR-2) checklist.

TAKEAWAY:

• All reviews that included meta-analyses showed significant associations between perceived ethnic discrimination and psychotic symptoms (adjusted odds ratio [aOR], 1.78; 95% CI, 1.3-2.5) and psychotic experiences (pooled OR, 1.9; 95% CI, 1.4-2.7).
• Perceived racial or ethnic discrimination was also strongly linked to delusional symptoms (OR, 2.5; 95% CI, 1.6-4.0) and hallucinatory symptoms (OR, 1.65; 95% CI, 1.3-2.1).
• The largest of the included studies showed a dose-response relationship between higher levels of lifetime perceived racial or ethnic discrimination and greater likelihood of psychotic experiences.
• More robust associations were found in nonclinical populations compared to clinical ones, but there were significant associations in both.

IN PRACTICE:

“Our review was only looking at the impact of a person directly perceiving racism or interpersonal racial or ethnic discrimination; it may be that systemic racism, which can go unseen but still have profound impacts, could further contribute to mental health disparities,” lead investigator India Francis-Crossley, University College London, London, UK, said in a press release.

SOURCE:

The study was published online in PLOS Mental Health. 

LIMITATIONS:

The evidence was primarily based on cross-sectional studies and was limited by high heterogeneity. The reviews included showed low or critically low AMSTAR-2 quality scores, which may have affected the robustness of the findings. More robust evidence was observed for psychotic outcomes in nonclinical populations compared to clinical samples. Additionally, the study potentially exacerbated errors or misreporting in the original reviews and did not include relevant structural factors such as income, education, housing, and poverty.

DISCLOSURES:

The study was funded by the University College London-Windsor Fellowship Research Opportunities scholarship, Wellcome Trust PhD Fellowship in Mental Health Science, Mental Health Mission Early Psychosis Workstream, and UK Research and Innovation funding for the Population Mental Health Consortium.

TOPLINE:

Offspring of parents with mental disorders had nearly double the risk for mortality, especially from unnatural causes, compared to those with parents did not have a mental disorder, a new Swedish cohort study showed. Additionally, mortality risk was highest when both parents had mental disorders but was not affected by the sex of the affected parent.

METHODOLOGY:

• A nationwide register-based cohort study in Sweden included more than 3.5 million individuals born between 1973 and 2014 (51% men); 35% had a parent with a mental disorder (13% paternal, 16% maternal, and 6% both parents).
• Mental disorder categories included alcohol or substance use, psychotic, mood, anxiety or stress-related, eating, and personality disorders and intellectual disability. Exposure timing was classified by offspring age (mean age, 15.8 years) at parental diagnosis.
• Participants were followed up from birth until death, the death of either parent, emigration (up to 2014), either parent’s emigration, or the end of 2023, whichever came first (median follow-up duration, 20.1 years).
• The main outcome was all-cause mortality; secondary outcomes were deaths from natural and unnatural causes, as well as deaths from cardiovascular disease, cancer, suicide, and unintentional injuries. Cousin comparison analyses were also conducted to account for confounding.

TAKEAWAY:

• During the follow-up, offspring exposed to parental psychiatric disorders had higher overall mortality rates than unexposed offspring (7.9 vs 3.55 per 10,000 person-years). Mortality rates due to natural causes were 4.0 vs 2.4 per 10,000 person-years and were 3.95 vs 1.1 per 10,000 person-years for mortality due to unnatural causes.
• Exposed offspring had an increased risk for mortality due to any cause (adjusted hazard ratio [aHR], 2.1), natural causes (aHR, 1.9), and unnatural causes (aHR, 2.45). Exposure was also associated with an increased risk for cardiovascular and cancer-related death, suicide, and death due to unintentional injuries. The associations remained significant, although slightly attenuated, in cousin comparison analyses.
• The highest risks for mortality were in offspring exposed at ages 1-2 years to both parents having mental disorders (HR for natural causes, 4.5; HR for unnatural causes, 5.3).
• The risk varied by the type of parental mental disorder, with HRs ranging from 1.6 for eating disorders to 2.2 for intellectual disability.

IN PRACTICE:

“Our findings highlight the need for improved surveillance, prevention, and early detection strategies to reduce the risk of premature mortality among offspring exposed to parental mental disorders. Whether additional support for families affected by mental disorders could mitigate the risk warrants further investigation,” the investigators wrote.

SOURCE:

This study was led by Hui Wang, PhD, Karolinska Institutet, Stockholm, Sweden. It was published online in JAMA Psychiatry.

LIMITATIONS:

Reliance on registry data may have led to the misclassification of parental mental disorders. The study lacked data on genetic factors, parenting quality, cohabitation, and social support, and its generalizability may have been limited. Immigration data after 2014 were unavailable, potentially leading to misclassifications of exposure and outcomes. The Patient Register did not distinguish between diagnoses made in general vs psychiatric hospital settings, and cousin comparisons remained susceptible to bias from unmeasured confounding and may have been limited in capturing temporal and familial heterogeneity.

Steatocystomas are small sebum-filled cysts that typically manifest in the dermis and originate from sebaceous follicles. Although commonly asymptomatic, these lesions can manifest with pruritus or become infected, predisposing patients to further complications.¹ Steatocystomas can manifest as single (steatocystoma simplex [SS]) or numerous (steatocystoma multiplex [SM]) lesions; the lesions also can spontaneously rupture with characteristics that resemble hidradenitis suppurativa (HS)(steatocystoma multiplex suppurativa [SMS]).^1,2

Steatocystomas are relatively rare, and there is limited consensus in the published literature on the etiology and management of this condition. In this article, we present a comprehensive review of steatocystomas in the current literature. We highlight important features to consider when making the diagnosis and also offer recommendations for best-practice treatment.

Historical Background

Although not explicitly identified by name, the first documentation of steatocystomas is a case report published in 1873. In this account, the author described a patient who presented with approximately 250 flesh-colored dermal cysts across the body that varied in size.³ In 1899, the term steatocystoma multiple—derived from Greek roots meaning “fatty bag”—was first used.⁴

In 1982, almost a century later, Brownstein⁵ reported some of the earliest cases of SS. This solitary subtype is identical to SM on a microscopic level; however, unlike SM, this variant occurs as a single lesion that typically forms in adulthood and in the absence of family history. Other benign adnexal tumors (eg, pilomatricomas, pilar cysts, and sebaceous hyperplasias) also can manifest as either solitary or multiple lesions.

In 1976, McDonald and Reed⁶ reported the first known cases of patients with both SM and HS. At the time, the co-occurrence of these conditions was viewed as coincidental, but there were postulations of a shared inflammatory process and hereditary link⁶; it was not until 1982 that the term steatocystoma multiplex suppurativum was coined to describe this variant.⁷ Although rare, there have been multiple documented instances of SMS since. It has been suggested that the convergence of these conditions may indicate a shared follicular proliferation defect.⁸ Ongoing investigation is warranted to explain the underlying pathogenesis of this unique variant.

Epidemiology

The available epidemiologic data primarily relate to SM, the most common steatocystoma variant. Nevertheless, SM is a relatively rare condition, and the exact incidence and prevalence remain unknown.^8,9 Steatocystomas typically manifest in the first and second decades of life and have been observed in patients of both sexes, with studies demonstrating no notable sex bias.^4,9

Etiology and Pathophysiology

Steatocystomas can occur sporadically or may be inherited as an autosomal-dominant condition.⁴ Typically, SS tends to manifest as an isolated occurrence without any inherent genetic predisposition.⁵ Alternatively, SM may develop sporadically or be associated with a mutation in the keratin 17 gene (KRT17).⁴ Steatocystoma multiplex also has been associated with at least 4 different missense mutations, including N92H, R94H, and R94C, located on the long (q) arm of chromosome 17.^4,10-12

The keratin 17 gene is responsible for encoding the keratin 17 protein, a type I intermediate filament predominantly synthesized in the basal cells of epithelial tissue. This fibrous structural protein can regulate many processes, including inflammation and cell proliferation, and is found in regions such as the sebaceous glands, hair follicles, and eccrine sweat glands. Overexpression of KRT17 has been suggested in other cutaneous conditions, most notably psoriasis.¹² Despite KRT17’s many roles, it remains unclear why SM typically manifests with a myriad of sebum-containing cysts as the primary symptom.¹² Continued investigation into the genetic underpinnings of SM and the keratin 17 protein is necessary to further elucidate a more comprehensive understanding of this condition.

Hormonal influences have been suggested as a potential trigger for steatocystoma growth.^4,13 This condition is associated with dysfunction of the sebaceous glands, and, correspondingly, the incidence of disease is highest in pubertal patients, in whom androgen levels and sebum production are elevated.^4,13,14 Two cases of transgender men taking testosterone therapy presenting with steatocystomas provide additional clinical support for this association.¹⁵

Additionally, the use of immunomodulatory agents, such as ustekinumab (anti–interleukin 12/interleukin 23), has been shown to trigger SM. It is predicted that the reduced expression of certain interferons and interleukins may lead to downstream consequences in the keratin 17 pathway and lead to SM lesion formation in genetically susceptible individuals.¹⁶ Targeting these potential causes in the future may prove efficacious in the secondary prevention of familial SM manifestation or exacerbations.

Mutations in the KRT17 gene also have been implicated in pachyonychia congenita type 2 (PC-2).⁴ Marked by extensive systemic hyperkeratosis, PC-2 has been observed to coincide with SM in certain patients.^4,5 Interestingly, the location of the KRT17 mutations are identical in both PC-2 and SM.⁴ Although most individuals with hereditary SM do not exhibit the characteristic features of PC-2, mild nail and dental abnormalities have been observed in some SM cases.^4,10 This relationship suggests that SM may be a less severe variant of PC-2 or part of a complex polygenetic spectrum of disease.¹⁰ Further research is imperative to determine the exact nature and extent of the relationship between these conditions.

Clinical Manifestations

Steatocystomas are flesh-colored subcutaneous cysts that range in size from less than 3 mm to larger than 3 cm in diameter (Figure). They form within a single pilosebaceous unit and typically display firm attachment due to their origination in the dermis.^2,7,17 Steatocystomas generally contain lipid material, and less frequently, keratin and hair shafts, distinguishing them as the only “true” sebaceous cysts.¹⁸ Their color can range from flesh-toned to yellow, with reports of occasional dark-blue shades and calcifications.^19,20 Steatocystomas can persist indefinitely, and they usually are asymptomatic.

Diagnosis of steatocystoma is confirmed by biopsy.⁴ Steatocystomas are characterized by a dermal cyst lined by stratified squamous cell epithelium (eFigures 1 and 2).²¹ Classically they feature flattened sebaceous lobules, multinucleated giant cells, and abortive hair follicles. The lining of these cysts is marked by lymphocytic infiltrate and a dense, wrinkled, eosinophilic keratin cuticle that replaces the granular layer.²² The cyst maintains an epidermal connection through a follicular infundibulum characterized by clumps of keratinocytes, sebocytes, corneocytes, and/or hair follicles.⁷ Aspirated contents reveal crystalline structures and anucleate squamous cells upon microscopic analysis. That being said, variable histologic findings of steatocystomas have been described.²³

Steatocystoma simplex, as the name implies, classifies a single isolated steatocystoma. This subtype exhibits similar histopathologic and clinical features to the other subtypes of steatocystomas. Notably, SS is not associated with a genetic mutation and is not an inherited condition within families.⁵ Steatocystoma multiplex manifests with many steatocystomas, often distributed widely across the body.^3,4 The chest, axillae, and groin are the most common locations; however, these cysts can manifest on the face, back, abdomen, and extremities.^4,18-22 Rare occurrences of SM limited to the face, scalp, and distal extremities have been documented.^18,21,24,25 Due to the possibility of an autosomal-dominant inheritance, it is advisable to take a comprehensive family history in patients for whom SM is in the differential.¹⁷

Steatocystoma multiplex—especially familial variants—has been shown to develop in conjunction with other dermatologic conditions, including eruptive vellus hair (EVH) cysts, persistent infantile milia, and epidermoid/dermoid cysts.²⁶ While some investigators regard these as separate entities due to their varied genetic etiology, it has been suggested that these conditions may be related and that the diagnosis is determined by the location of cyst origin along the sebaceous ducts.^26,27 Other dermatologic conditions and lesions that frequently manifest comorbidly with SM include hidrocystomas, syringomas, pilonidal cysts, lichen planus, nodulocystic acne, trichotillomania, trichoblastomas, trichoepithelioma, HS, keratoacanthomas, acrokeratosis verruciformis of Hopf, and embryonal hair formation. Steatocystoma multiplex, manifesting comorbidly with dental and orofacial malformations (eg, partial noneruption of secondary teeth, natal and defective teeth, and bilateral preauricular sinuses) has been classified as SM natal teeth syndrome.⁶

Steatocystoma multiplex suppurativa is a rare and serious variant of SM characterized by inflammation, cyst rupture, sinus tract formation, and scarring.²⁴ Patients with SMS typically have multiple intact SM cysts, which can aid in differentiation from HS.^2,24 Steatocystoma multiplex suppurativa is associated with more complications than SS and SM, including cyst perforation, development of purulent and/or foul-smelling discharge, infection, scarring, pain, and overall discomfort.²

Given its rarity and the potential manifestations that overlap with other conditions, steatocystomas easily can be misdiagnosed. In some clinical instances, EVHs may share similar characteristics with SM; however, certain distinguishing features exist, including a central tuft of protruding hairs and different expressed contents, such as the vellus hair shafts, from the cyst’s lumen.²⁸ Furthermore, histologic examination of EVHs reveals epidermoid keratinization of the lining as well as a lack of sebaceous glands within the wall.^28,29 Other similar conditions include epidermoid cysts, pilar cysts, lipomas, epidermal inclusion cysts, dermoid cysts, sebaceous hyperplasia, folliculitis, xanthomas, neurofibromatosis, and syringomas.³⁰ Occasionally, SMS can be mistaken for HS or acne conglobata, and SM lesions with a facial distribution can mimic acne vulgaris.^1,31 These conditions should be excluded before a diagnosis of SS, SM, or SMS is made. 

Importantly, SM is visually indistinguishable from subcutaneous metastasis on physical examination, and there are reports of oncologic conditions (eg, pulmonary adenocarcinoma metastasized to the skin) being mistaken for SS or SM.³² Therefore, a thorough clinical examination, histopathologic analysis, and potential use of other imaging modalities such as ultrasonography (US) are needed to ensure an accurate diagnosis.

Ultrasonography has demonstrated utility in diagnosing steatocystomas.^33-35 Steatocystomas have incidentally been found on routine mammograms and can demonstrate well-defined circular nodules with radiolucent characteristics and a thin radiodense outline.^33,36 Homogeneous hypoechoic nodules within the dermis without posterior acoustic features generally are observed (eFigure 3).^33,37 In patients declining biopsy, US may be useful in further characterization of an unknown lesion. Color Doppler US can be used to distinguish SMS from HS. Specifically, SM typically exhibits an absence of Doppler signaling due to a lack of vascularity, providing a helpful diagnostic clue for the SMS variant.³³

Management and Treatment Options

There is no established standard treatment for steatocystomas; therefore, the approach to management is contingent on clinical presentation and patient preferences. Various medical, surgical, and laser management options are available, each with its own advantages and limitations. Treatment of SM is difficult due to the large number of lesions.³⁸ In many cases, continued observation is a viable treatment option, as most SS and SM lesions are asymptomatic; however, cosmetic concerns can be debilitating for patients with SM and may warrant intervention.³⁹ More extensive medical and surgical management often are necessary in SMS due to associated morbidity. Discussing options and goals as well as setting realistic expectations with the patient are essential in determining the optimal approach.

Medical Management—In medical literature, oral isotretinoin (13-cis-retinoic acid) has been the mainstay of therapy for steatocystoma, as its effect on the size and activity of sebaceous glands is hypothesized to decrease disease activity.^38,40 Interventional studies and case reports have exhibited varying degrees of effectiveness.^1,38-41 Some reports depict a reduction in the formation of new lesions and a decrease in the size of pre-existing lesions, some show mild delayed therapeutic efficacy, and others suggest exacerbation of the condition.^1,38-41 This outcome variability is attributed to isotretinoin’s preferential efficacy in treating inflammatory lesions.^40,42

Tetracycline derivatives and intralesional steroid injections also have been employed with some efficacy in patients with focal inflammatory SM and SMS.⁴³ There is limited evidence on the long-term outcomes of these interventions, and intralesional injections often are not recommended in conditions such as SM, in which there are many lesions present.

Surgical Management—Minimally invasive surgical procedures including drainage and resections have been used with varying efficacy in SS and SM. Typically, a 2- to 3-mm incision or sharp-tipped cautery is employed to puncture the cyst. Alternatively, radiofrequency probes with a 2.4-MHz frequency setting have been used to minimize incision size.⁴⁴ The contents then are expressed with manual pressure or forceps, and the cyst sac is extracted using forceps and/or a vein hook (eFigure 4).^44,45 The specific surgical techniques and their respective advantages and limitations are summarized in the eTable. Reported advantages and limitations of surgical techniques are derived from information provided by the authors of steatocystoma case reports, which are based on observations of a very limited sample size.

Laser Treatment—Various laser modalities have been used in the management of steatocystomas, including carbon dioxide lasers, erbium-doped yttrium aluminum garnet lasers, 1450-nm diode plus 1550-nm fractionated erbium-doped fiber lasers, and 1927-nm diode lasers.^54,55-57 These lasers are used to perforate the cyst before extirpation and have displayed advantages in minimizing scar length.⁵⁸ The super-pulse mode of carbon dioxide lasers demonstrates efficacy with minimal scarring and recurrence, and this mode is preferred to minimize thermal damage.^54,59 Furthermore, this modality can be especially useful in patients whose condition is refractory to other noninvasive options.⁵⁹ Similarly, the erbium-doped yttrium aluminum garnet laser was well tolerated with no complications noted.⁵⁵ The 1927-nm diode laser also displayed good outcomes as well as no recurrence.⁵⁷ With laser use, it is important to note that multiple treatments are needed to see optimal outcomes.⁵⁴ Moreover, laser settings must be carefully considered, especially in patients with Fitzpatrick skin type III or higher, and topical anti-inflammatory agents should be considered posttreatment to minimize complications.^54,59,60

Recommendations

For management of SS, we recommend conservative therapy of watchful observation, as scarring or postinflammatory pigment change may be brought on by medical or surgical therapy; however, if SS is cosmetically bothersome, laser or surgical excision can be done (eFigure 4).^4,43-53 It is important to counsel the patient on risks/benefits. For SM, watchful observation also is indicated; however, systemic therapies aimed at prevention may be the most efficacious by limiting disease progression, and oral tetracycline or isotretinoin may be tried.⁴ Tetracyclines have the risk for photosensitivity and are teratogenic, while isotretinoin is extremely teratogenic, requires laboratory monitoring and regular pregnancy tests in women, and often causes substantial mucosal dryness. If lesions are bothersome or refractory to these therapies, intralesional steroids or surgical/laser procedures can be tried throughout multiple visits.^43-53 For SMS, systemic therapies frequently are recommended. The risks of systemic tetracycline and isotretinoin therapies must be discussed. Patients with treatment-refractory SMS may require surgical excision or deroofing of sinus tracts.^43-53 This management is similar to that of HS and must be tailored to the patient.

Conclusion

Overall, steatocystomas are a relatively rare pathology, with a limited consensus on their etiology and management. This review summarizes the current knowledge on the condition to support clinicians in diagnosis and management, ranging from watchful waiting to surgical removal. By individualizing treatment plans, clinicians ultimately can optimize outcomes in patients with steatocystomas.

At the time, the co-occurrence of these conditions was viewed as coincidental, but there were postulations of a shared inflammatory process and hereditary link⁶; it was not until 1982 that the term steatocystoma multiplex suppurativum was coined to describe this variant.⁷ Although rare, there have been multiple documented instances of SMS since. It has been suggested that the convergence of these conditions may indicate a shared follicular proliferation defect.⁸ Ongoing investigation is warranted to explain the underlying pathogenesis of this unique variant.

Epidemiology

The available epidemiologic data primarily relate to SM, the most common steatocystoma variant. Nevertheless, SM is a relatively rare condition, and the exact incidence and prevalence remain unknown.^8,9 Steatocystomas typically manifest in the first and second decades of life and have been observed in patients of both sexes, with studies demonstrating no notable sex bias.^4,9

Etiology and Pathophysiology

Steatocystomas can occur sporadically or may be inherited as an autosomal-dominant condition.⁴ Typically, SS tends to manifest as an isolated occurrence without any inherent genetic predisposition.⁵ Alternatively, SM may develop sporadically or be associated with a mutation in the keratin 17 gene (KRT17).⁴ Steatocystoma multiplex also has been associated with at least 4 different missense mutations, including N92H, R94H, and R94C, located on the long (q) arm of chromosome 17.^4,10-12

The keratin 17 gene is responsible for encoding the keratin 17 protein, a type I intermediate filament predominantly synthesized in the basal cells of epithelial tissue. This fibrous structural protein can regulate many processes, including inflammation and cell proliferation, and is found in regions such as the sebaceous glands, hair follicles, and eccrine sweat glands. Overexpression of KRT17 has been suggested in other cutaneous conditions, most notably psoriasis.¹² Despite KRT17’s many roles, it remains unclear why SM typically manifests with a myriad of sebum-containing cysts as the primary symptom.¹² Continued investigation into the genetic underpinnings of SM and the keratin 17 protein is necessary to further elucidate a more comprehensive understanding of this condition.

Hormonal influences have been suggested as a potential trigger for steatocystoma growth.^4,13 This condition is associated with dysfunction of the sebaceous glands, and, correspondingly, the incidence of disease is highest in pubertal patients, in whom androgen levels and sebum production are elevated.^4,13,14 Two cases of transgender men taking testosterone therapy presenting with steatocystomas provide additional clinical support for this association.¹⁵

Additionally, the use of immunomodulatory agents, such as ustekinumab (anti–interleukin 12/interleukin 23), has been shown to trigger SM. It is predicted that the reduced expression of certain interferons and interleukins may lead to downstream consequences in the keratin 17 pathway and lead to SM lesion formation in genetically susceptible individuals.¹⁶ Targeting these potential causes in the future may prove efficacious in the secondary prevention of familial SM manifestation or exacerbations.

Mutations in the KRT17 gene also have been implicated in pachyonychia congenita type 2 (PC-2).⁴ Marked by extensive systemic hyperkeratosis, PC-2 has been observed to coincide with SM in certain patients.^4,5 Interestingly, the location of the KRT17 mutations are identical in both PC-2 and SM.⁴ Although most individuals with hereditary SM do not exhibit the characteristic features of PC-2, mild nail and dental abnormalities have been observed in some SM cases.^4,10 This relationship suggests that SM may be a less severe variant of PC-2 or part of a complex polygenetic spectrum of disease.¹⁰ Further research is imperative to determine the exact nature and extent of the relationship between these conditions.

Clinical Manifestations

Steatocystomas are flesh-colored subcutaneous cysts that range in size from less than 3 mm to larger than 3 cm in diameter (Figure). They form within a single pilosebaceous unit and typically display firm attachment due to their origination in the dermis.^2,7,17 Steatocystomas generally contain lipid material, and less frequently, keratin and hair shafts, distinguishing them as the only “true” sebaceous cysts.¹⁸ Their color can range from flesh-toned to yellow, with reports of occasional dark-blue shades and calcifications.^19,20 Steatocystomas can persist indefinitely, and they usually are asymptomatic.

Diagnosis of steatocystoma is confirmed by biopsy.⁴ Steatocystomas are characterized by a dermal cyst lined by stratified squamous cell epithelium (eFigures 1 and 2).²¹ Classically they feature flattened sebaceous lobules, multinucleated giant cells, and abortive hair follicles. The lining of these cysts is marked by lymphocytic infiltrate and a dense, wrinkled, eosinophilic keratin cuticle that replaces the granular layer.²² The cyst maintains an epidermal connection through a follicular infundibulum characterized by clumps of keratinocytes, sebocytes, corneocytes, and/or hair follicles.⁷ Aspirated contents reveal crystalline structures and anucleate squamous cells upon microscopic analysis. That being said, variable histologic findings of steatocystomas have been described.²³

Steatocystoma simplex, as the name implies, classifies a single isolated steatocystoma. This subtype exhibits similar histopathologic and clinical features to the other subtypes of steatocystomas. Notably, SS is not associated with a genetic mutation and is not an inherited condition within families.⁵ Steatocystoma multiplex manifests with many steatocystomas, often distributed widely across the body.^3,4 The chest, axillae, and groin are the most common locations; however, these cysts can manifest on the face, back, abdomen, and extremities.^4,18-22 Rare occurrences of SM limited to the face, scalp, and distal extremities have been documented.^18,21,24,25 Due to the possibility of an autosomal-dominant inheritance, it is advisable to take a comprehensive family history in patients for whom SM is in the differential.¹⁷

Steatocystoma multiplex—especially familial variants—has been shown to develop in conjunction with other dermatologic conditions, including eruptive vellus hair (EVH) cysts, persistent infantile milia, and epidermoid/dermoid cysts.²⁶ While some investigators regard these as separate entities due to their varied genetic etiology, it has been suggested that these conditions may be related and that the diagnosis is determined by the location of cyst origin along the sebaceous ducts.^26,27 Other dermatologic conditions and lesions that frequently manifest comorbidly with SM include hidrocystomas, syringomas, pilonidal cysts, lichen planus, nodulocystic acne, trichotillomania, trichoblastomas, trichoepithelioma, HS, keratoacanthomas, acrokeratosis verruciformis of Hopf, and embryonal hair formation. Steatocystoma multiplex, manifesting comorbidly with dental and orofacial malformations (eg, partial noneruption of secondary teeth, natal and defective teeth, and bilateral preauricular sinuses) has been classified as SM natal teeth syndrome.⁶

Steatocystoma multiplex suppurativa is a rare and serious variant of SM characterized by inflammation, cyst rupture, sinus tract formation, and scarring.²⁴ Patients with SMS typically have multiple intact SM cysts, which can aid in differentiation from HS.^2,24 Steatocystoma multiplex suppurativa is associated with more complications than SS and SM, including cyst perforation, development of purulent and/or foul-smelling discharge, infection, scarring, pain, and overall discomfort.²

Given its rarity and the potential manifestations that overlap with other conditions, steatocystomas easily can be misdiagnosed. In some clinical instances, EVHs may share similar characteristics with SM; however, certain distinguishing features exist, including a central tuft of protruding hairs and different expressed contents, such as the vellus hair shafts, from the cyst’s lumen.²⁸ Furthermore, histologic examination of EVHs reveals epidermoid keratinization of the lining as well as a lack of sebaceous glands within the wall.^28,29 Other similar conditions include epidermoid cysts, pilar cysts, lipomas, epidermal inclusion cysts, dermoid cysts, sebaceous hyperplasia, folliculitis, xanthomas, neurofibromatosis, and syringomas.³⁰ Occasionally, SMS can be mistaken for HS or acne conglobata, and SM lesions with a facial distribution can mimic acne vulgaris.^1,31 These conditions should be excluded before a diagnosis of SS, SM, or SMS is made. 

Importantly, SM is visually indistinguishable from subcutaneous metastasis on physical examination, and there are reports of oncologic conditions (eg, pulmonary adenocarcinoma metastasized to the skin) being mistaken for SS or SM.³² Therefore, a thorough clinical examination, histopathologic analysis, and potential use of other imaging modalities such as ultrasonography (US) are needed to ensure an accurate diagnosis.

Ultrasonography has demonstrated utility in diagnosing steatocystomas.^33-35 Steatocystomas have incidentally been found on routine mammograms and can demonstrate well-defined circular nodules with radiolucent characteristics and a thin radiodense outline.^33,36 Homogeneous hypoechoic nodules within the dermis without posterior acoustic features generally are observed (eFigure 3).^33,37 In patients declining biopsy, US may be useful in further characterization of an unknown lesion. Color Doppler US can be used to distinguish SMS from HS. Specifically, SM typically exhibits an absence of Doppler signaling due to a lack of vascularity, providing a helpful diagnostic clue for the SMS variant.³³

Management and Treatment Options

There is no established standard treatment for steatocystomas; therefore, the approach to management is contingent on clinical presentation and patient preferences. Various medical, surgical, and laser management options are available, each with its own advantages and limitations. Treatment of SM is difficult due to the large number of lesions.³⁸ In many cases, continued observation is a viable treatment option, as most SS and SM lesions are asymptomatic; however, cosmetic concerns can be debilitating for patients with SM and may warrant intervention.³⁹ More extensive medical and surgical management often are necessary in SMS due to associated morbidity. Discussing options and goals as well as setting realistic expectations with the patient are essential in determining the optimal approach.

Medical Management—In medical literature, oral isotretinoin (13-cis-retinoic acid) has been the mainstay of therapy for steatocystoma, as its effect on the size and activity of sebaceous glands is hypothesized to decrease disease activity.^38,40 Interventional studies and case reports have exhibited varying degrees of effectiveness.^1,38-41 Some reports depict a reduction in the formation of new lesions and a decrease in the size of pre-existing lesions, some show mild delayed therapeutic efficacy, and others suggest exacerbation of the condition.^1,38-41 This outcome variability is attributed to isotretinoin’s preferential efficacy in treating inflammatory lesions.^40,42

Tetracycline derivatives and intralesional steroid injections also have been employed with some efficacy in patients with focal inflammatory SM and SMS.⁴³ There is limited evidence on the long-term outcomes of these interventions, and intralesional injections often are not recommended in conditions such as SM, in which there are many lesions present.

Surgical Management—Minimally invasive surgical procedures including drainage and resections have been used with varying efficacy in SS and SM. Typically, a 2- to 3-mm incision or sharp-tipped cautery is employed to puncture the cyst. Alternatively, radiofrequency probes with a 2.4-MHz frequency setting have been used to minimize incision size.⁴⁴ The contents then are expressed with manual pressure or forceps, and the cyst sac is extracted using forceps and/or a vein hook (eFigure 4).^44,45 The specific surgical techniques and their respective advantages and limitations are summarized in the eTable. Reported advantages and limitations of surgical techniques are derived from information provided by the authors of steatocystoma case reports, which are based on observations of a very limited sample size.

Laser Treatment—Various laser modalities have been used in the management of steatocystomas, including carbon dioxide lasers, erbium-doped yttrium aluminum garnet lasers, 1450-nm diode plus 1550-nm fractionated erbium-doped fiber lasers, and 1927-nm diode lasers.^54,55-57 These lasers are used to perforate the cyst before extirpation and have displayed advantages in minimizing scar length.⁵⁸ The super-pulse mode of carbon dioxide lasers demonstrates efficacy with minimal scarring and recurrence, and this mode is preferred to minimize thermal damage.^54,59 Furthermore, this modality can be especially useful in patients whose condition is refractory to other noninvasive options.⁵⁹ Similarly, the erbium-doped yttrium aluminum garnet laser was well tolerated with no complications noted.⁵⁵ The 1927-nm diode laser also displayed good outcomes as well as no recurrence.⁵⁷ With laser use, it is important to note that multiple treatments are needed to see optimal outcomes.⁵⁴ Moreover, laser settings must be carefully considered, especially in patients with Fitzpatrick skin type III or higher, and topical anti-inflammatory agents should be considered posttreatment to minimize complications.^54,59,60

Recommendations

For management of SS, we recommend conservative therapy of watchful observation, as scarring or postinflammatory pigment change may be brought on by medical or surgical therapy; however, if SS is cosmetically bothersome, laser or surgical excision can be done (eFigure 4).^4,43-53 It is important to counsel the patient on risks/benefits. For SM, watchful observation also is indicated; however, systemic therapies aimed at prevention may be the most efficacious by limiting disease progression, and oral tetracycline or isotretinoin may be tried.⁴ Tetracyclines have the risk for photosensitivity and are teratogenic, while isotretinoin is extremely teratogenic, requires laboratory monitoring and regular pregnancy tests in women, and often causes substantial mucosal dryness. If lesions are bothersome or refractory to these therapies, intralesional steroids or surgical/laser procedures can be tried throughout multiple visits.^43-53 For SMS, systemic therapies frequently are recommended. The risks of systemic tetracycline and isotretinoin therapies must be discussed. Patients with treatment-refractory SMS may require surgical excision or deroofing of sinus tracts.^43-53 This management is similar to that of HS and must be tailored to the patient.

Conclusion

Overall, steatocystomas are a relatively rare pathology, with a limited consensus on their etiology and management. This review summarizes the current knowledge on the condition to support clinicians in diagnosis and management, ranging from watchful waiting to surgical removal. By individualizing treatment plans, clinicians ultimately can optimize outcomes in patients with steatocystomas.

Steatocystomas are small sebum-filled cysts that typically manifest in the dermis and originate from sebaceous follicles. Although commonly asymptomatic, these lesions can manifest with pruritus or become infected, predisposing patients to further complications.¹ Steatocystomas can manifest as single (steatocystoma simplex [SS]) or numerous (steatocystoma multiplex [SM]) lesions; the lesions also can spontaneously rupture with characteristics that resemble hidradenitis suppurativa (HS)(steatocystoma multiplex suppurativa [SMS]).^1,2

Steatocystomas are relatively rare, and there is limited consensus in the published literature on the etiology and management of this condition. In this article, we present a comprehensive review of steatocystomas in the current literature. We highlight important features to consider when making the diagnosis and also offer recommendations for best-practice treatment.

Historical Background

Although not explicitly identified by name, the first documentation of steatocystomas is a case report published in 1873. In this account, the author described a patient who presented with approximately 250 flesh-colored dermal cysts across the body that varied in size.³ In 1899, the term steatocystoma multiple—derived from Greek roots meaning “fatty bag”—was first used.⁴

In 1982, almost a century later, Brownstein⁵ reported some of the earliest cases of SS. This solitary subtype is identical to SM on a microscopic level; however, unlike SM, this variant occurs as a single lesion that typically forms in adulthood and in the absence of family history. Other benign adnexal tumors (eg, pilomatricomas, pilar cysts, and sebaceous hyperplasias) also can manifest as either solitary or multiple lesions.

In 1976, McDonald and Reed⁶ reported the first known cases of patients with both SM and HS. At the time, the co-occurrence of these conditions was viewed as coincidental, but there were postulations of a shared inflammatory process and hereditary link⁶; it was not until 1982 that the term steatocystoma multiplex suppurativum was coined to describe this variant.⁷ Although rare, there have been multiple documented instances of SMS since. It has been suggested that the convergence of these conditions may indicate a shared follicular proliferation defect.⁸ Ongoing investigation is warranted to explain the underlying pathogenesis of this unique variant.
