HONOLULU – During office visits with Andrew Blauvelt, MD, MBA, many patients well controlled on biologic therapy for their moderate to severe psoriasis often ask him when their scheduled injections can stop.

The most common question he hears is, “ ‘Why do I have to keep doing this? I’ve been clear for 2 or 3 years,’ ” Dr. Blauvelt, president of Oregon Medical Research Center, Portland, said at the Hawaii Dermatology Seminar provided by MedscapeLIVE! “We have terrific drugs for psoriasis, but how can we do better?”

According to Dr. Blauvelt, there are at least six future strategies to treat psoriasis, induce remission, and/or cure the disease:

Development of oral biologics. At least two companies are developing a peptide-type small molecule that blocks interleukin (IL)-17 or IL-23 signaling, but would be given as a pill, he said. Another concept in the works is a robotic pill for drug delivery. The pill, which is being developed by Rani Therapeutics, protects the biotherapeutic drug payload from digestion in the GI tract and auto-injects it into the wall of the small intestine, according to a report of two studies that demonstrated the safety and tolerability of the robotic pill in healthy humans.

In an animal study, the same researchers showed that delivering monoclonal antibodies with the robotic pill achieved bioavailability on par with that obtained by standard subcutaneous injections.

Identifying “super responders” who require less frequent dosing of medication. “There’s data to suggest that we can kind of back off treatment in these patients,” Dr. Blauvelt said.

Hitting treatment hard and early. “There’s a concept in medicine of hitting disease hard and hitting it early, before the disease can establish itself and cause damage,” he said.

Targeting tissue resident memory T cells. In psoriasis, the idea is that if you treat earlier, when patients are just diagnosed, “perhaps you might be able to decrease resident memory T cells that set up shop in the skin and are responsible for disease recurrences,” Dr. Blauvelt said. “Research has shown that IL-23 blockers decrease tissue resident memory T cells, and IL-17 blockers don’t. This could explain why we see long remissions in this class of drug because we’re getting at these resident memory T cells and knocking them down,” he explained. “Our hypothesis is that hitting hard and early in the treatment course with high-dose IL-23 blockade may be an effective strategy to induce long-term remissions and possible cure, what we call ‘knock-out therapy.’ ”

In a pilot study of 20 patients, Dr. Blauvelt and colleagues are evaluating whether higher initial doses of the IL-23 antagonist risankizumab (300 mg and 600 mg, 2 times and 4 times the standard initial doses for plaque psoriasis) can more effectively target resident memory T cells. “This involves dosing at weeks 0, 4, and 16, then stopping and measuring resident T cells in the tissue to see how long we can induce psoriasis remissions,” Dr. Blauvelt said.

“I have no data to share, but I think we have the potential for unprecedented PASI-100 numbers with no added safety concerns, and the potential to break away from established regular dosing patterns,” such as the possibility of yearly dosing, the possibility of long-term remissions, and the possibility of cure in some patients, he noted.

Inducing tolerance. This refers to efforts aimed at increasing regulatory T cells, which are natural T cells that calm inflammation. He described it as “revving up our natural anti-inflammatory T cells to help balance the immune system.”

Gene editing. This involves using CRISPR gene editing technology to cut genes as a way to cure disease. “What if we cut the IL-23 receptor?” Dr. Blauvelt asked. “You would get rid of that whole signaling pathway. Would the patient be fine?”

In an interview a the meeting, Linda Stein Gold, MD, director of clinical research and division head of dermatology at the Henry Ford Health System, Detroit, said that Dr. Blauvelt “has a very exciting view” of the future of psoriasis treatments. “I think that some of it will come true; we’ll have to see which,” Dr. Stein Gold said. “The idea that we might be able to change the trajectory of disease by being aggressive upfront, and possibly modify the course, is exciting. That would be a wonderful new treatment approach.”

The Diagnosis: Discoid Lupus Erythematosus

The biopsies demonstrated vacuolar interface changes with superficial and deep perivascular and periadnexal inflammation as well as increased background mucin deposition. The clinical morphology and distributions of the plaques limited to the photoexposed areas of the head suggested a diagnosis of discoid lupus erythematosus (DLE). The interface changes on histopathology supported this clinical impression. Our patient was treated with limited application of triamcinolone ointment 0.1% twice daily around the ears and neck, tacrolimus ointment 0.1% twice daily on the face, and hydroxychloroquine, as well as sun protection instructions. Smoking cessation was strongly advised.

Discoid lupus erythematosus is a disorder with chronic, erythematous, scaly, coin-shaped (discoid) plaques and is the most common form of chronic cutaneous lupus erythematosus.¹ Lesions usually present on sun-exposed areas of the face, scalp, neck, ears, lips, or upper torso. They expand slowly with an active peripheral margin and a central scar that can result in induration, pigmentation changes, telangiectases, pruritus, or tenderness. Hair-bearing areas may be involved, causing hair loss due to follicular plugging; irreversible scarring alopecia can result. Facial DLE often spares the nasolabial folds. Ear involvement characteristically includes the conchal bowl and the outer external auditory canal. Discoid lupus erythematosus is considered localized if most of the head and neck region is involved or generalized if lesions also are present below the neck. Risk factors for DLE include genetic and environmental factors such as UV exposure, hormones, or exposure to toxins such as cigarette smoke.¹ The disorder most commonly affects females and has a higher prevalence in patients of African descent than in Asian and White patients. Disease can occur at any age but usually occurs between 20 and 40 years of age.² Discoid lupus erythematosus and other forms of chronic cutaneous lupus can occur independently or in conjunction with systemic lupus erythematosus (SLE), and approximately 15% to 30% of SLE patients develop DLE.¹

Discoid lupus erythematosus is clinically diagnosed by the presentation of plaques in the characteristic distribution with confirmation via skin biopsy.¹ Elman et al³ created a system for DLE classification that was only clinical and did not involve histopathology. Histologically, DLE often includes basement membrane thickening, follicular keratin plugs, mucin deposition, and vacuolar change with an interface, and a perivascular and periadnexal lymphocytic infiltrate.^3,4 Antibodies such as antinuclear antibodies, rheumatoid factor, anti–double-stranded DNA, anti-Smith, and Sjögren syndrome A and B antibodies may be present (albeit with low positive frequency) in cutaneous lupus erythematosus.4 Characteristics of SLE also may be present, helping to confirm the diagnosis. Because there is an association of DLE with SLE, various laboratory tests should be ordered, including complete blood cell count, renal function panel, inflammatory markers, antibodies, and urinalysis for proteinuria.^2,4

Treatment of DLE consists of preventative measures, such as sun protection with vitamin D supplementation, avoidance of drug triggers, and smoking cessation, as well as pharmacotherapy. The importance of wearing sun protective hats and garments with sunscreen use cannot be understated.¹ Smoking cessation should be advised because smoking reduces the efficacy of antimalarial treatment and potentially increases the likelihood of patients requiring a second antimalarial drug. Quinacrine often is noted in both the dermatology and rheumatology literature to be used for escalating cutaneous lupus erythematosus care when hydroxychloroquine is ineffective or not tolerated, but no US manufacturer produces this medication; thus, compounding is required, which may be financially prohibitive, making this recommendation difficult to translate into clinical practice.⁵ Firstline therapy for acute flares is high-potency topical corticosteroids. If lesions are primarily on areas other than the face, a medium-potency topical steroid may be used. Topical calcineurin inhibitors or intralesional corticosteroids may be used if minimal improvement is seen after initial topical corticosteroid therapy. Treatment for widespread disease or disease that is resistant to local treatment is systemic therapy with antimalarial agents, followed by antimetabolites, systemic retinoids, thalidomide, or dapsone.^1,2 The Cutaneous Lupus Erythematosus Disease Area and Severity Index is a valid tool to gauge the degree of disease and to help with disease progression and treatment response by noting the features of the plaques.¹

Patients also should be educated that this disease can last for years, and long-standing DLE plaques infrequently can give rise to squamous cell carcinoma. In addition, isolated DLE can progress to SLE in 5% to 28% of patients.²

The differential diagnosis in our patient included other diseases with violaceous annular lesions and central clearing. Majocchi granuloma usually presents in areas of prior trauma, possibly due to shaving the face in our patient, or in the setting of topical corticosteroid use or immunosuppression. Scaling often is present within lesions, and histology shows fungal elements.⁶ Cutaneous sarcoidosis usually presents on the face, with scarring alopecia when appearing on the scalp; histology shows noncaseating granulomas, and 70% of patients with cutaneous symptoms will have systemic sarcoidosis.⁷ Granuloma annulare most commonly presents on the extremities, and histology shows lymphohistiocytic granulomas in a palisaded or interstitial pattern with connective-tissue degeneration and mucinous deposits.⁸ Annular psoriasis often is scaly and symmetric with parakeratosis, epidermal hyperplasia, dilated dermal capillaries, loss of granular layer, perivascular mononuclear cell infiltrate, and elongation of rete ridges on histology.⁹ Drug-induced lupus erythematosus always should be considered in patients taking triggering drugs such as antihypertensives, lipid-lowering drugs, antifungals, anti–tumor necrosis factor drugs, and proton pump inhibitors—the latter being a drug our patient was taking.¹⁰

HONOLULU – In the clinical experience of John S. Barbieri, MD, MBA, cheilitis occurs in nearly all patients taking any dose of isotretinoin.

“If they don’t have dry lips, you have to wonder if they’re even absorbing isotretinoin,” Dr. Barbieri, director of the Advanced Acne Therapeutics Clinic at Brigham and Women’s Hospital, Boston, said at the Hawaii Dermatology Seminar provided by MedscapeLIVE! “Everyone is going to get dry lips.”

According to a retrospective review of 1,743 patients started on isotretinoin, other common mucocutaneous side effects include eczema, nose bleeds, and eye problems. Emerging research suggests that there may be a role for oral omega-3 in decreasing such side effects of the drug. In a case control study, 118 patients were randomized to isotretinoin alone or isotretinoin plus 1 g/day of oral omega-3 for 16 weeks. At week 16, the rate of dry lips was 26% in the isoretinoin only group compared with 14% in the combination group; similar trends were seen with dry nose (11% vs. 0 %, respectively) and dry skin (11% vs. 2%).

“Omega-3 is a simple thing that we can think about recommending for patients,” Dr. Barbieri said. “It’s very safe, inexpensive, and it may help us manage these common sides effect we run into.”

Another potential side effect of isotretinoin that he characterized as underappreciated is chronic dry eye and other ocular changes. One retrospective cohort study of 14,682 adolescents and young adults in Israel found that use of the drug resulted in reduced tear production and reduced tear quality. In another study, a review and meta-analysis of 21 publications involving 1,105 eyes of 842 patients, isotretinoin use was associated with increased conjunctival fluorescein staining, decreased corneal thickness, and worse patient-reported ocular surface disease index scores.

“These changes may be mediated by meibomian gland dysfunction and atrophy,” Dr. Barbieri said. “Fortunately, many of these tear film changes appear to resolve after treatment. Those changes in corneal thickness do seem to get better. That’s reassuring.”

In a study of 54 patients treated with isotretinoin, tear production and quality returned to baseline within 6 months of treatment completion. “But some changes in the meibomian gland may be persistent,” Dr. Barbieri said. “At 6 and 12 months after the end of treatment, you can still see changes in the meibomian glands of patients who were treated with a standard course of 120 to 150 mg/kg isotretinoin,” he said, referring to the results of a study of 88 patients .

One study investigated the effects of omega-3 fatty acids and punctal plugs on tear film and ocular surface parameters in 90 patients receiving systemic isotretinoin therapy. They were divided into three groups: Those who received a soft preloaded silicone plug that was inserted in the inferior punctum of both eyes and received oral omega-3 fatty acid capsules twice daily for a total dose of 1,040 mg/day for 6 months; those who received a soft preloaded silicone plug and oral placebo, and those who received isotretinoin alone. At 6 months’ follow-up, those who were treated with omega-3 combined with the preloaded silicone plug had better meibomian gland function than did those who received isotretinoin alone or isotretinoin with the preloaded silicone plug.

Dr. Barbieri also noted that antihistamines may play a role in enhancing the effect of isotretinoin. In one study, 20 patients were treated with isotretinoin 0.4 mg/kg per day and 20 patients were also treated with an antihistamine, desloratadine 5 mg/day for 12 weeks. At week 12, patients in the group treated with isotretinoin and the antihistamine showed a more statistically significant decrease in acne lesion counts, compared with the isotretinoin-only group (reductions of 44.8% vs. 17.8%, respectively, in noninflammatory lesions; 55.8% vs. 22.9% in inflammatory lesions, and 45.6% vs. 18.7% in total lesions (P < .05 for all associations).

A subsequent larger study yielded similar findings. There were also lower rates of initial flaring and higher rates of patient satisfaction in the antihistamine groups in both studies.

In an interview at the meeting, Lawrence F. Eichenfield, MD, chief of pediatric and adolescent dermatology at Rady Children’s Hospital, San Diego, described Dr. Barbieri as “a leader in taking a comprehensive view on what the history and latest information is on isotretinoin. His fresh approach is something everyone should consider and figure out what they can use in their practice.”

HONOLULU – In the clinical experience of John S. Barbieri, MD, MBA, cheilitis occurs in nearly all patients taking any dose of isotretinoin.

“If they don’t have dry lips, you have to wonder if they’re even absorbing isotretinoin,” Dr. Barbieri, director of the Advanced Acne Therapeutics Clinic at Brigham and Women’s Hospital, Boston, said at the Hawaii Dermatology Seminar provided by MedscapeLIVE! “Everyone is going to get dry lips.”

According to a retrospective review of 1,743 patients started on isotretinoin, other common mucocutaneous side effects include eczema, nose bleeds, and eye problems. Emerging research suggests that there may be a role for oral omega-3 in decreasing such side effects of the drug. In a case control study, 118 patients were randomized to isotretinoin alone or isotretinoin plus 1 g/day of oral omega-3 for 16 weeks. At week 16, the rate of dry lips was 26% in the isoretinoin only group compared with 14% in the combination group; similar trends were seen with dry nose (11% vs. 0 %, respectively) and dry skin (11% vs. 2%).

“Omega-3 is a simple thing that we can think about recommending for patients,” Dr. Barbieri said. “It’s very safe, inexpensive, and it may help us manage these common sides effect we run into.”

Another potential side effect of isotretinoin that he characterized as underappreciated is chronic dry eye and other ocular changes. One retrospective cohort study of 14,682 adolescents and young adults in Israel found that use of the drug resulted in reduced tear production and reduced tear quality. In another study, a review and meta-analysis of 21 publications involving 1,105 eyes of 842 patients, isotretinoin use was associated with increased conjunctival fluorescein staining, decreased corneal thickness, and worse patient-reported ocular surface disease index scores.

“These changes may be mediated by meibomian gland dysfunction and atrophy,” Dr. Barbieri said. “Fortunately, many of these tear film changes appear to resolve after treatment. Those changes in corneal thickness do seem to get better. That’s reassuring.”

In a study of 54 patients treated with isotretinoin, tear production and quality returned to baseline within 6 months of treatment completion. “But some changes in the meibomian gland may be persistent,” Dr. Barbieri said. “At 6 and 12 months after the end of treatment, you can still see changes in the meibomian glands of patients who were treated with a standard course of 120 to 150 mg/kg isotretinoin,” he said, referring to the results of a study of 88 patients .

SAN DIEGO – Today’s molecular tests for managing melanoma patients are used to reclassify melanoma, identify patients at risk, as well as for diagnosis, prognosis, and treatment, but each one has its specific applications, benefits, and drawbacks, according to Gregory A. Hosler, MD, PhD.

At the annual Cutaneous Malignancy Update, Dr. Hosler, director of dermatopathology for ProPath, highlighted the following molecular tests currently used for the diagnosis of challenging melanocytic lesions:

Comparative genomic hybridization (CGH). This technique allows for the detection of chromosomal copy number changes throughout the tumor genome. “With CGH, test (tumor) DNA and normal DNA are differentially labeled and compared to a reference library. Gains and losses of portions of the tumor genome are determined by comparing the relative signals from these two groups,” said Dr. Hosler, clinical professor of pathology and dermatology at the University of Texas Southwestern Medical Center, Dallas.

“In the past, your library was a metaphase of spread of chromosomes, which introduced technical challenges and made performance of the assay labor intensive. Because of this, CGH is not routinely performed by clinical laboratories and is used more as an exploratory/research technique.”

Array CGH (also known as SNP array). Newer versions of CGH use short DNA sequences that are tiled onto a chip. “The interesting thing about these chips is that you can purchase them or design them on your own,” Dr. Hosler said. “The chips may cover the entire genome or cover specific areas of the genome at higher resolution.” One upside of array CGH, he continued, is that it allows one to detect essentially all gains or losses of chromosomal material in a single reaction. “It is not subject to the artifacts associated with cutting thin sections like with fluorescence in situ hybridization (FISH); it can detect copy number neutral loss of heterozygosity, and it is more scalable,” Dr. Hosler said at the meeting, which was hosted by Scripps MD Anderson Cancer Center.

One downside of array CGH is that does not allow one to analyze specific cells, “so if you have a tumor that’s heterogeneous, the assay is agnostic to this and spits out a result based on all the material provided,” he said. “You can’t parse out different areas of the lesion. It also does not track balanced translocations.” In addition, he said, “there are also questions about reimbursement and these are lab-developed tests, so each lab’s assay is different. Finally, it requires specialized equipment and expertise for interpretation.”

FISH. First-generation melanoma FISH assays, which became available in 2009, used six probes and four colors and had a sensitivity of about 87% and specificity of about 95%, Dr. Hosler said, but there were problems with those assays, particularly related to Spitz nevi. Spitz nevi often duplicate their chromosomes, “so instead of being diploid they’re tetraploid,” he said.

“The second-generation melanoma FISH assays addressed this by adding centromeres to the assay, and targeted probes could be compared to the centromeres on the same chromosome to determine if these were true copy number gains, due to genetic instability, or gains or losses of entire arms or whole chromosomes. This modification and the addition of new targets really improved upon the sensitivity and specificity (94% and 98%, respectively),” he said, noting that this assay is widely used.

Upsides of melanoma FISH assays are that they are a “fairly routine methodology” in large clinical laboratories, he said, and that many labs are familiar with interpretation. “I would say the biggest advantage to FISH is its ability to analyze specific cells, which is useful with small or heterogeneous tumors,” Dr. Hosler said. “Also, there is a genetic reimbursement code for it, and it yields diagnostic and potentially prognostic information.” For example, certain copy number changes have shown to portend a worse prognosis if they’re present in a melanocytic tumor, including alterations in CDKN2A, CCND1, MYC, topoisomerase, and BAP1.

Downsides of melanoma FISH assays are that they are expensive, labor-intensive, and require experts to interpret the results. “The stacking and truncation of cell nuclei innate to paraffin-embedded FISH make interpretation difficult,” he said. “Also, all colors cannot be viewed simultaneously, and each lab’s assay potentially is different, requiring validation. These are not [Food and Drug Administration]-approved tests.”

Next generation sequencing (NGS). Also known as high-throughput sequencing, this technique allows for the generation of millions of sequencing reads that are aligned to a standard human genome, and likely represents the wave of the future. “With NGS you can increase breadth, so you can sequence the entire genome if you want, but you can also increase depth, meaning increasing the number of reads over a single target of the genome,” Dr. Hosler said. “That’s useful if you’re looking for a low frequency mutation.”

For example, NGS allows one to detect alterations of BRAF and KIT and other potentially actionable alterations. It can also be used to detect mutations in benign and malignant melanocytic lesions, including historically diagnostically challenging Spitz and desmoplastic subgroups. Several different NGS technologies exist, and there are different strategies behind each assay, including whole genome sequencing, whole exome sequencing, transcriptome sequencing, and targeted panels. “I’ve seen panels of 10 and I’ve seen panels of 1,500; there’s a wide range,” Dr. Hosler said. “The biggest challenge with NGS, currently, is that it’s difficult to interpret. Trying to figure out what’s important and what’s not important can be challenging. Often you need a team of people who are experts in bioinformatics to interpret these results.”

Slow turnaround time is another downside. “It can take a month to get results, and sometimes clinicians don’t want to wait that long, especially if they think a lesion is melanoma, so that’s an area of focus for NGS laboratories,” he said. “And there are questions on reimbursement. If you run NGS on every unusual melanocytic lesion, that’s not a good use of health care dollars. Who’s paying for it? I don’t have an answer for you. It’s all over the map right now. Each lab’s test and billing practice is different.”

Dr. Hosler reported having no relevant financial disclosures. ProPath is a nationwide pathology practice.

Antibiotics were associated with 28% of all cases of Stevens-Johnson syndrome and toxic epidermal necrolysis, according to the first meta-analysis to examine the worldwide prevalence of SJS/TEN in connection with antibiotics.

“SJS/TEN is considered the most severe form of drug hypersensitivity reaction, and antibiotics are an important risk,” Erika Yue Lee, MD, and associates wrote in JAMA Dermatology.

Their analysis, which involved 38 studies published since 1987 with 2,917 patients from more than 20 countries, showed that 86% of all SJS/TEN cases were associated with a single drug, with the rest involving multiple drug triggers, infections, or other causes. More than a quarter (28%) of those patients had used an antibiotic, and the sulfonamides were the class most often triggering SJS/TEN, said Dr. Lee of the University of Toronto and associates.

Sulfonamides were responsible for 32% of the antibiotic-associated cases, which works out to 11% of all SJS/TEN cases included in the analysis. Penicillins were next with 22% of all antibiotic-associated cases, followed by the cephalosporins (11%), fluoroquinolones (4%), and macrolides (2%), the investigators reported.

A subgroup analysis conducted by age indicated that “there was no difference in the proportion of antibiotics associated with SJS/TEN between adult and pediatric groups,” they noted.

There were differences, however, among the various antibiotic classes. Sulfonamides represented 54% of antibiotic-triggered reactions in children, compared with 25% in adults, but adults were significantly more likely to have cephalosporin (23%) and fluoroquinolone (5%) involvement than were children (2% and 0, respectively). Macrolide-induced SJS/TEN was more common in children (18% vs. 1%), while the penicillin rate was 18% for both age groups, Dr. Lee and associates said.

A second subgroup analysis establishing the proportion of antibiotic-induced SJS/TEN by continent ranked Australia highest with 43%, but that was based on only one study of 42 patients. North America was slightly lower at 37%, but the analysis included 14 studies and 932 patients. Asia’s 16 studies and 1,298 patients were divided into three regions, with the lowest being the southeast at 16%, according to the researchers.

“Global sulfonamide antibiotic use has been decreasing since 2000 despite an ongoing upward trend of use in other antibiotic classes,” they wrote, but “antibiotics remain one of the most common culprit drugs for SJS/TEN in both adults and children worldwide.”

One of Dr. Lee’s associates has received personal fees from Janssen, AstraZeneca, UpToDate, Verve, BioCryst, Regeneron Pharmaceuticals, and Novavax and has served as codirector of IIID Pty Ltd, which holds a patent for HLA-B*57:01 testing and has a patent pending for detection of HLA-A*32:01 in connection with diagnosing drug reaction without any financial remuneration outside this study.

Penicillins were next with 22% of all antibiotic-associated cases, followed by the cephalosporins (11%), fluoroquinolones (4%), and macrolides (2%), the investigators reported.

A subgroup analysis conducted by age indicated that “there was no difference in the proportion of antibiotics associated with SJS/TEN between adult and pediatric groups,” they noted.

There were differences, however, among the various antibiotic classes. Sulfonamides represented 54% of antibiotic-triggered reactions in children, compared with 25% in adults, but adults were significantly more likely to have cephalosporin (23%) and fluoroquinolone (5%) involvement than were children (2% and 0, respectively). Macrolide-induced SJS/TEN was more common in children (18% vs. 1%), while the penicillin rate was 18% for both age groups, Dr. Lee and associates said.

A second subgroup analysis establishing the proportion of antibiotic-induced SJS/TEN by continent ranked Australia highest with 43%, but that was based on only one study of 42 patients. North America was slightly lower at 37%, but the analysis included 14 studies and 932 patients. Asia’s 16 studies and 1,298 patients were divided into three regions, with the lowest being the southeast at 16%, according to the researchers.

“Global sulfonamide antibiotic use has been decreasing since 2000 despite an ongoing upward trend of use in other antibiotic classes,” they wrote, but “antibiotics remain one of the most common culprit drugs for SJS/TEN in both adults and children worldwide.”

One of Dr. Lee’s associates has received personal fees from Janssen, AstraZeneca, UpToDate, Verve, BioCryst, Regeneron Pharmaceuticals, and Novavax and has served as codirector of IIID Pty Ltd, which holds a patent for HLA-B*57:01 testing and has a patent pending for detection of HLA-A*32:01 in connection with diagnosing drug reaction without any financial remuneration outside this study.

Antibiotics were associated with 28% of all cases of Stevens-Johnson syndrome and toxic epidermal necrolysis, according to the first meta-analysis to examine the worldwide prevalence of SJS/TEN in connection with antibiotics.

“SJS/TEN is considered the most severe form of drug hypersensitivity reaction, and antibiotics are an important risk,” Erika Yue Lee, MD, and associates wrote in JAMA Dermatology.

Their analysis, which involved 38 studies published since 1987 with 2,917 patients from more than 20 countries, showed that 86% of all SJS/TEN cases were associated with a single drug, with the rest involving multiple drug triggers, infections, or other causes. More than a quarter (28%) of those patients had used an antibiotic, and the sulfonamides were the class most often triggering SJS/TEN, said Dr. Lee of the University of Toronto and associates.

Sulfonamides were responsible for 32% of the antibiotic-associated cases, which works out to 11% of all SJS/TEN cases included in the analysis.

A frustrated physician recently voiced some strong words in Medscape’s US Physician Burnout & Depression Report: “Only a sociopath could work for a large health system and not be burned out. Anyone who cares about patients is doomed to burnout.”

It’s no secret that today’s large health care organizations are leaving physicians feeling overwhelmed, beaten up, and exhausted. Medscape’s report showed that 53% of physicians feel burned out by job requirements; 65% say that burnout has impacted their relationships, and other statistics say that physicians are leaving clinical medicine because of all this pressure.

What is it about being employed by large organizations that can be so negative?  In another study, MEMO – Minimizing Error, Maximizing Outcomes – researchers at the University of Wisconsin surveyed more than 400 doctors to learn about how their working environments corresponded with medical errors. More than half of the physicians reported time pressures when conducting physical examinations. Nearly a third felt they needed at least 50% more time than was allotted for this patient care function, and nearly a quarter said they needed at least 50% more time for follow-up appointments.

Some have asked: Can anyone, then, thrive in today’s health care environment and avoid burnout?

Although the frustrated physician noted above may sardonically say that a doctor needs to be sociopathic to enjoy it – lacking in feelings for others – “It’s a very small number of doctors who get in it for the wrong reasons and therefore care about their own benefit and not their patients,” said psychiatrist Wendy Dean, MD, CEO and cofounder of Moral Injury of Healthcare, a nonprofit organization addressing workforce distress in health care. “Those are the outliers.”

The vast majority of physicians do care about their patients – deeply, said Dr. Dean. They struggle under the weight of the health care system and yet must find ways to get through. Today, thriving in an imperfect system requires honing new skills, asking for help when needed, and pushing for systemic and cultural change.

“We’ve been assessing and trying to address burnout for half a century,” said Dr. Dean. “Despite all the good intentions, and people dedicating their entire careers to solving the issue, we’ve barely made a dent.”

With the advent of new technological requirements on the job and more demands from increasingly larger health care organizations, the risk for burnout is higher than ever before. “There’s an increased burden of regulatory-mandated and cumbersome administrative workload per patient,” said Shomron Ben-Horin, MD, cofounder of Evinature. “Often the computer/paperwork before and after a procedure is much longer than the procedure itself.”

Meeting insurance requirements is increasingly cumbersome, too, and preauthorizations and debates with payers over medical approval may put physicians frustratingly in the middle.

“This increases the psychological burden for physicians who may feel responsible for wrongdoing no matter which option they deem better,” Dr. Ben-Horin said. “Add in physician accessibility around the clock via mobile phones, emails, and apps, and you end up on call even if you’re not officially on call.”
 

Why some physicians suffer more

Some physicians are more likely to suffer burnout than others, said Jessi Gold, MD, assistant professor in the department of psychiatry at Washington University in St. Louis. “The self-valuation concept comes into play here,” she said. “If you make a mistake, do you blame yourself or see it as a growth opportunity? If it’s the former, you’re more likely to burn out.”

Dr. Ben-Horin added that the most patient-centric doctors are the ones who struggle most. “These are the doctors we’d all love to have as a patient,” he said. “But they are burdened by the extra tasks of the job, and they are the most stressed by the environment.”

So too are those physicians who never master compartmentalizing their feelings and emotions. “We learn in training to compartmentalize our emotions,” said Dr. Dean. “You can’t allow yourself to get emotional while performing chest compressions on an 18-year-old kid. So you shut it all away; otherwise, you might lose the patient.”

This turn-off switch becomes automatic, but it also comes at a cost. “When doctors were interviewed about [Buffalo Bills player] Damar Hamlin going into cardiac arrest on the football field, they talked about how a life-and-death situation is so common that they have to put the emotions away, work on the patient, and move onto the next,” said Dr. Dean. “The next patient needs you just as much. We must lock away our feelings and manage the situation.”

Dr. Gold explained that burying feelings, however, is a symptom of burnout. “We have to remove ourselves from the situation to protect ourselves,” she said. “We can’t cry in these situations, but we can’t bury our feelings either.”

Instead, Dr. Gold suggested, a good medium may exist. “You may not be able to address them in the moment, but you should sometime after,” she said.

This is just a starting point on how to remain a dedicated, caring physician without burning out. “The system is pretty broken, and to survive it first means wanting to survive it,” Dr. Gold said. “There’s a lot of focus on resiliency and lack thereof if a physician expresses burnout, but that’s a false notion. Doctors are a resilient bunch but even they get burned out.”

Change for the better must come from several places. One is asking for help, something that can be hard for a group conditioned to keeping a stiff upper lip. “Just because your peers might look healthy (emotionally) doesn’t mean they are,” said Dr. Gold. “We’ve normalized this culture of burying feelings, but that doesn’t mean it’s right.”

Dr. Ben-Horin also advocates diversifying your work. This might include engaging in research and academics, for instance. “This not only makes you a better broad-perspective doctor but allows you to psychologically switch gears on research days,” he said.

The biggest place to make change, however, is within the health care system culture itself. The AMA created a series of recommendations to address burnout at the resident and fellow level, a good starting point to carry through into staff work. The steps include creating a well-being framework, gathering a team to support a well-being program, developing the program in a way to foster fun and connectivity among the staff, fostering individual well-being that addresses emotional and physical well-being, and confronting burnout and creating a sustainable culture of well-being.

On a personal level, it’s essential that physicians keep close tabs on themselves and peers. “Understand the signs and symptoms of burnout by taking stock of where you are emotionally,” said Dr. Gold. “Have a place and time at the end of a hard day to reflect or find a ritual that helps you and stay with it.”

You might also reach out to a therapist or a peer when you’re struggling. Having honest conversations with peers can go a long way. “Find a confidant that allows you to be vulnerable,” Dr. Gold recommended. “Acknowledge that this is hard and that you might need help taking care of yourself. The system needs to change, but we can also learn to survive in the meantime. You don’t have to be a sociopath to make it.”

Many companies, government agencies, and organizations have implemented policies and procedures to shield employees from sexual and other forms of harassment. The U.S. Department of Health & Human Services and the American Medical Association are just two examples.

Employers can tap a rich lode of guidance and resources to craft these antiharassment policies. The National Institutes of Health’s resource page is a good site for hospitals to check out.

But how effective have official policies proved in deterring harassment in medical workplaces? After all, in a study by the American Association of Medical Colleges, 34% of female faculty said they had experienced sexual harassment irrespective of such policies. And in a recent Medscape survey of more than 3,000 physicians, 27% reported that they had either witnessed or been subjected to sexual harassment or misconduct at work during the past 4 years.
 

When policies are absent or unenforced

“Not all institutions have antiharassment rules and policies, and even when they exist, they’re not always enforced,” says Theresa Rohr-Kirchgraber, MD, president of the American Medical Women’s Association and professor of medicine at the Medical College of Georgia, Augusta.

She believes employer rules and policies generally are helpful in establishing who fields harassment complaints and in creating at least some accountability.

On the other hand, policies that don’t recognize anonymous complaints effectively discourage harassment victims from coming forward, Dr. Rohr-Kirchgraber argues. Even those policies that do allow anonymous complaints may have limitations.

For example, the NIH policy on reporting harassment acknowledges that “officials must follow up on all allegations of harassment and cannot guarantee that your identity will not become apparent during the process. Please note that if you remain anonymous, key details about the allegation or concern [may] be omitted. This will limit the NIH’s ability to conduct an inquiry and take corrective action as warranted.”
 

Risks in pressing a harassment case

A complainant whose name becomes public risks getting a reputation as a problem employee or suffering workplace retaliation, according to Dr. Rohr-Kirchgraber. She recalls a colleague who was on a clinical education track until she lodged a harassment complaint. Abruptly, she was told she was needed on a service with fewer teaching opportunities.

With such risks in mind, respondents to the Medscape survey advised employees in medical workplaces to familiarize themselves with policies and procedures before pressing a case.

“Document everything,” an ophthalmologist urged, including time, place, offender, and witnesses. Present that information to your supervisor, and if nothing is done, hire a lawyer, a gastroenterologist suggested.

But taking the situation to the Equal Employment Opportunity Commission can be complicated, Roberta Gebhard, DO, past AMWA president and founder of its Gender Equity Task Force, told this news organization.

“They talk to the employer and get the employer’s side of the story and eventually render a decision about whether you have a case you can put through and file a lawsuit,” she said. “I don’t know of any other situation in which you need ‘permission’ to file a lawsuit.”

Nevertheless, an attorney can be helpful with cases, and when someone is terminated, a lawyer can possibly have it overturned or converted to a resignation, Dr. Gebhard said.

“And always have a lawyer review your contract before you take the job,” she advised. The lawyer might adjust the contract’s verbiage in ways that can protect one down the road in the event of a potential termination. “It’s money very well spent.”
 

More education needed

Dr. Rohr-Kirchgraber said that protection against harassment goes beyond the employer’s policies and procedures. Building an overall consciousness of what harassment is should begin with employee onboarding, she said.

“The harasser may not even recognize that what they’re doing or saying is a form of harassment, so we need better education,” Dr. Rohr-Kirchgraber emphasized.

On the other hand, policies that don’t recognize anonymous complaints effectively discourage harassment victims from coming forward, Dr. Rohr-Kirchgraber argues. Even those policies that do allow anonymous complaints may have limitations.

For example, the NIH policy on reporting harassment acknowledges that “officials must follow up on all allegations of harassment and cannot guarantee that your identity will not become apparent during the process. Please note that if you remain anonymous, key details about the allegation or concern [may] be omitted. This will limit the NIH’s ability to conduct an inquiry and take corrective action as warranted.”
 

Risks in pressing a harassment case

A complainant whose name becomes public risks getting a reputation as a problem employee or suffering workplace retaliation, according to Dr. Rohr-Kirchgraber. She recalls a colleague who was on a clinical education track until she lodged a harassment complaint. Abruptly, she was told she was needed on a service with fewer teaching opportunities.

With such risks in mind, respondents to the Medscape survey advised employees in medical workplaces to familiarize themselves with policies and procedures before pressing a case.

“Document everything,” an ophthalmologist urged, including time, place, offender, and witnesses. Present that information to your supervisor, and if nothing is done, hire a lawyer, a gastroenterologist suggested.

But taking the situation to the Equal Employment Opportunity Commission can be complicated, Roberta Gebhard, DO, past AMWA president and founder of its Gender Equity Task Force, told this news organization.

“They talk to the employer and get the employer’s side of the story and eventually render a decision about whether you have a case you can put through and file a lawsuit,” she said. “I don’t know of any other situation in which you need ‘permission’ to file a lawsuit.”

Nevertheless, an attorney can be helpful with cases, and when someone is terminated, a lawyer can possibly have it overturned or converted to a resignation, Dr. Gebhard said.

“And always have a lawyer review your contract before you take the job,” she advised. The lawyer might adjust the contract’s verbiage in ways that can protect one down the road in the event of a potential termination. “It’s money very well spent.”
 

More education needed

Dr. Rohr-Kirchgraber said that protection against harassment goes beyond the employer’s policies and procedures. Building an overall consciousness of what harassment is should begin with employee onboarding, she said.

“The harasser may not even recognize that what they’re doing or saying is a form of harassment, so we need better education,” Dr. Rohr-Kirchgraber emphasized.

ORLANDO – From differentiating them from mimics to choosing the best treatment course, Molly Hinshaw, MD, reviewed some of the ins and outs of managing nail disorders at the ODAC Dermatology, Aesthetic, & Surgical Conference.

Dr. Hinshaw, professor of dermatology at the University of Wisconsin, Madison, reviewed several disorders and provided guidance on diagnosis, and achieving the best outcomes for patients.

Pyogenic granuloma (PG) in the nail: These are benign vascular tumors that can mimic more serious conditions, Dr. Hinshaw said. In adults, PG requires a histologic diagnosis, she said.

“So these all really should have a biopsy,” because of potential confusion with amelanotic melanoma or squamous cell carcinoma, she said, although in children, a biopsy is likely not necessary.

Treatment with topical beta-blockers can be effective for PG, she said, and avoids the scarring seen with surgical removal. “These are benign conditions – we want them to go away, but we want these patients to have a functional nail thereafter.”

Periungual or subungual warts: For these warts, which are alongside or under the nail, destructive approaches can cause scarring of the nail bed and are far from optimal, she said.

“We’d like to avoid that, of course.” Therefore, treatments such as lasers and liquid nitrogen “would be much further down, if at all, on my list,” she said.

Injections of the antiviral cidofovir, into the dermis right under the wart, can be highly effective, and one or two treatments is often enough, Dr. Hinshaw said. Sometimes, local anesthesia isn’t even needed for the injection, she said. “This is a wonderful option,” she added.

SAN DIEGO – When parents bring their children to Caroline Piggott, MD, to evaluate a suspicious mole on the scalp or other body location, the vast majority turn out to be benign, because the incidence of melanoma is rare, especially before puberty.

“Only 1%-2% of all melanomas in the world are in children, so most of my job is to provide reassurance,” Dr. Piggott, a pediatric dermatologist at Scripps MD Anderson Cancer Center, San Diego, said at the annual Cutaneous Malignancy Update. “Few pediatric studies exist. Why? Because children are excluded from most melanoma clinical trials. Our management is based mainly on adult National Comprehensive Cancer Network guidelines.”

To help parents identify melanoma, clinicians typically recommend the “ABCDE” rule, for Asymmetry, Border irregularity, Color variation (especially dark or multiple colors), Diameter greater than 6 mm, and Evolving (is it changing, bleeding or painful?).

While Dr. Piggott considers the standard ABCDE rules as important – especially in older children and teenagers – researchers led by Kelly M. Cordoro, MD, professor of dermatology at the University of California, San Francisco, proposed a modified ABCD criteria based on evaluating a cohort of 60 children who were diagnosed with melanoma and 10 who were diagnosed with ambiguous melanocytic tumors treated as melanoma before age 20 years at UCSF from 1984 to 2009.

The researchers divided patients into two groups: those aged 0-10 years (19; group A) and those aged 11-19 years (51; group B), and found that 60% of children in group A and 40% of those in group B did not present with conventional ABCDE criteria for children. Of the 60 melanoma patients, 10 died. Of these, 9 were older than age 10, and 70% had amelanotic lesions. Based on their analysis of clinical, histopathologic, and outcomes data, Dr. Cordoro and colleagues proposed additional ABCD criteria in which A stands for stands Amelanotic; B for Bleeding or Bump; C for Color uniformity, and D for De novo or any Diameter.

“This doesn’t mean you throw the old ABCDE criteria out the window,” Dr. Piggott said. “It means that you use this modified criteria in conjunction with the conventional ABCDE rules.”

Risk factors for melanoma in children are like those in adults, and include a family history of melanoma, large/giant congenital nevi, the presence of many atypical appearing nevi, having Fitzpatrick skin types I or II, a history of blistering sunburns, and the presence of genetic anomalies such as xeroderma pigmentosum.

According to an analysis of data from the Surveillance, Epidemiology, and End Results (SEER) Program, melanoma incidence increased in all individuals in the United States aged 0-19 years from 1973 to 2009. Key risk factors included White race, female sex, and living in a SEER registry categorized as low UVB exposure. Over the study period, boys experienced increased incidence rates of melanoma on the face and trunk, while girls experienced increased incidence rates of melanoma on the lower limbs and hip.

More recently, researchers extracted data from 988,103 cases of invasive melanoma in the 2001-2015 SEER database to determine the age-specific incidence of melanoma in the United States. In 2015, 83,362 cases of invasive melanoma were reported for all ages. Of these, only 67 cases were younger than age 10, while 251 were between the ages of 10 and 19 and 1,973 were young adults between the ages of 20 and 29.

In other findings, between 2006 and 2015, the overall incidence of invasive melanoma for all ages increased from 200 million to 229 cases per million person-years. “However, there were statistically significant decreases in melanoma incidence for individuals aged 10-19 years and for those aged 10-29 years,” said Dr. Piggott, who was not involved with the study. “The hypothesis is that public health efforts encouraging against sun exposure and tanning bed use may be influencing melanoma incidence in younger populations. What is interesting, though, is that young adult women have twice the melanoma risk as young adult men.”

In a separate study, researchers prospectively followed 60 melanoma-prone families for up to 40 years to evaluate the risk of pediatric melanoma in those with and without cyclin-dependent kinase inhibitor 2A (CDKN2A) mutations. Regardless of their CDKN2A status, the percentage of pediatric melanoma cases was 6- to 28-fold higher among melanoma-prone families, compared with the general population. In addition, families who were CDKN2A positive had a significantly higher rate of pediatric melanoma cases compared with those who were CDKN2A negative (11.1% vs. 2.5%; P = .004).

As for treating pediatric melanoma, the standard of care is similar to that for adults: usually wide local surgical excision of the primary lesion, depending on depth. Clinicians typically follow adult parameters for sentinel lymph node biopsy, such as lesion depth and ulceration.

“We know that a positive sentinel node does have prognostic value, but there is great debate on whether to do a lymph node dissection if the sentinel lymph node is positive,” Dr. Piggott said at the meeting, which was hosted by Scripps MD Anderson Cancer Center. “This is determined on a case-by-case basis. We consider factors such as, are the nodes palpable? Is there evidence on ultrasound? But there are no formal guidelines.”

Limited studies of systemic therapy in children exist because this population is excluded from most melanoma clinical trials. “In the past, interferon was sometimes used,” she said. “But in recent years, as with adults, we have started to use targeted immunologic therapy. This is usually managed by a tertiary academic oncology center.”

The chance of surviving pediatric melanoma is good if caught early. As in adults, the stage correlates strongly with survival, and distant metastases carry a poor prognosis.

In 2020, researchers published a retrospective, multicenter review of 38 cases of fatal pediatric melanoma between 1994 and 2017. The analysis was limited to individuals 20 years of age and younger who were cared for at 12 academic medical centers. Of the 38 patients, 42% were male, 58% were female, and 57% were White. In addition, 19% were Hispanic, “which is a larger percentage than fatalities in adult [Hispanic] populations with melanoma,” said Dr. Piggott, who was not involved in the study.

The mean age at diagnosis was 12.7 years, the mean age at death was 15.6 , and the mean survival time after diagnosis was about 35 months. Of the 16 cases with known identifiable subtypes, 50% were nodular, 31% were superficial spreading, and 19% were spitzoid melanoma. In addition, one-quarter of melanomas arose in association with congenital melanocytic nevi.

“The good news is that there are only 38 total cases of fatal pediatric melanoma between 12 academic centers over a 23-year period,” Dr. Piggott said. “Thanks goodness the number is that low.”

Dr. Piggott reported having no relevant disclosures.

San Diego – The way Benjamin Kelley, MD, sees it, the term dysplastic nevi (DN) suffers from an identity crisis, with different clinicians using different terms to describe a subset of melanocytic nevi that are clinically atypical.

Doug Brunk/MDedge News

“There’s a confusion in the terminology, a term the late A. Bernard Ackerman, MD, called ‘patho-babel,’ ” Dr. Kelley, a Mohs micrographic surgeon and dermatopathologist in La Jolla, Calif., said at the annual Cutaneous Malignancy Update. “The idea of DN was originally used to describe a clinical melanoma syndrome. Now we use it for individual lesions, not just clinically but histologically. Some dermatologists refer to DN as ‘pre-melanoma,’ which is a negative framing,” he noted.

“We also refer to common nevi as ‘benign,’ which implies that DN are not benign,” he added. “The good news is that regardless of what they are called, the histologic criteria is generally agreed upon. The names can be used interchangeably.”

The bad news, he continued, is that there is less-than-perfect interobserver variability for grading DN lesions and significant variability in the treatment recommendations that pathologists give to clinicians. In one study, a group of pathology experts was asked to review 48 photomicrographs of melanocytic lesions and provide their diagnosis and treatment recommendations based on the Melanocytic Pathology Assessment Tool and Hierarchy for Diagnosis scheme. For one, which showed a broad lesion with irregular epidermal thinning and thickening, the diagnoses ranged from solar lentigo to melanoma in situ. Treatment recommendations ranged from no treatment to re-excise with appropriate margins.

“This is an extreme example, but it shows you how difficult [establishing a diagnosis] can be,” Dr. Kelley said.

In a more recent study, researchers analyzed interobserver reproducibility in grading 179 DN cases among three observers who applied the 2018 World Health Organization grading criteria. The observers showed moderate to good agreement for most of the architectural features, except for criteria regarding focal continuous basal proliferation of melanocytes, density of non-nested junctional melanocytes, and presence of dyscohesive nests of intraepidermal melanocytes, whereas fair agreement was achieved for the cytological criteria. “So, it sounds to me like there was not a whole lot of agreement,” Dr. Kelley said.

An earlier single-center study titled “Clinicians Are From Mars and Pathologists Are From Venus” found that surgeons misunderstood the pathologist’s report 30% of the time.

In Dr. Kelly’s opinion, management of DNs will be successful if clinicians have a good working relationship with their dermatopathologists, if they biopsy to ensure an adequate, representative specimen, and if that they know what the terminology on the pathology report means and what actions to take. “The biopsy method matters,” he emphasized.

In a 14-year follow-up survey, investigators assessed DN management trends among 703 U.S. dermatologists. One key finding was that 69% of dermatologists in 2015 performed total removals when biopsying DN to achieve clear margins, compared with 86% in 2001.

A subsequent survey of 213 New England–based dermatologists found that the degree of clinical suspicion for melanoma was important in DN biopsy technique, with more respondents favoring shave biopsies for lesions with low suspicion and full-thickness biopsies for highly suspicious lesions.

“Misdiagnosis is more common for melanomas that have been assessed with punch and shave biopsies than with an excisional biopsy,” Dr. Kelley said. “I’m not too much of a stickler. I don’t require everyone to send me a giant excision, but I do want a representative sample.”

What about re-excision of DN considered to be mild or moderate? In 2015, members of the Pigmented Lesion Subcommittee of the Melanoma Prevention Working Group published a consensus statement on DN management recommendations for clinically atypical nevi/DN based on a review of published evidence. The subcommittee members concluded that mildly and moderately DN with clear margins do not need to be re-excised, and that mildly DN biopsied with positive histologic margins without clinical residual pigmentation may be safely observed rather than re-excised.

For moderately DN with positive histologic margins without clinically apparent residual pigmentation, the subcommittee members concluded that observation may be reasonable.

In his own informal analysis, Dr. Kelley compiled data from published studies he could find on DN management and divided them into two groups: the observation group, in which researchers from eight studies biopsied the DN lesion and watched the patients over time to see what happened, and the re-excision group, in which researchers from seven studies biopsied the DN lesion and subsequently re-excised it. There were about 1,500 patients in both groups. No deaths occurred in either group, he said, but 15 patients in the re-excision group developed a melanoma at the site of the original biopsy (1%), compared with 7 in the observation group (0.5%).

Six of seven melanomas in the observation group came from one article conducted at a VA clinic. In the study, 6 of 304 observed DN subsequently developed melanoma at the site of the lesion. “However, five of six that developed melanoma had an original biopsy that was a partial biopsy with grossly positive margins; I think that’s where the problem lies,” Dr. Kelley said at the meeting, which was hosted by Scripps MD Anderson Cancer Center. “All five grew lentigo maligna type melanoma, which we know can extend multiple millimeters beyond the clinically apparent lesion.”

The findings support mounting evidence that re-excising mild and moderate DN, regardless of border involvement, may not be necessary. “Currently, most clinicians still re-excise moderate and severe DN involving margins, especially if there is residual pigment,” Dr. Kelley said. “Most re-excise severe DN regardless of margin involvement, but beware if your biopsy was a partial sample of a larger lesion.”

He acknowledged limitations to pathologic studies of DN, including the potential for diagnostic uncertainty. “That doesn’t necessarily mean that the pathologist got the diagnosis wrong. It could be, what is the risk that the portion of tissue not visualized contains melanoma? If you give me a 5 mm sample of a DN, and I cut it into 4-micrometer sections, I’m only looking at less than 1% of the actual nevus. That’s compounded if the pathologist only receives a partial sample.”

San Diego – The way Benjamin Kelley, MD, sees it, the term dysplastic nevi (DN) suffers from an identity crisis, with different clinicians using different terms to describe a subset of melanocytic nevi that are clinically atypical.

“There’s a confusion in the terminology, a term the late A. Bernard Ackerman, MD, called ‘patho-babel,’ ” Dr. Kelley, a Mohs micrographic surgeon and dermatopathologist in La Jolla, Calif., said at the annual Cutaneous Malignancy Update. “The idea of DN was originally used to describe a clinical melanoma syndrome. Now we use it for individual lesions, not just clinically but histologically. Some dermatologists refer to DN as ‘pre-melanoma,’ which is a negative framing,” he noted.

“We also refer to common nevi as ‘benign,’ which implies that DN are not benign,” he added. “The good news is that regardless of what they are called, the histologic criteria is generally agreed upon. The names can be used interchangeably.”

The bad news, he continued, is that there is less-than-perfect interobserver variability for grading DN lesions and significant variability in the treatment recommendations that pathologists give to clinicians. In one study, a group of pathology experts was asked to review 48 photomicrographs of melanocytic lesions and provide their diagnosis and treatment recommendations based on the Melanocytic Pathology Assessment Tool and Hierarchy for Diagnosis scheme. For one, which showed a broad lesion with irregular epidermal thinning and thickening, the diagnoses ranged from solar lentigo to melanoma in situ. Treatment recommendations ranged from no treatment to re-excise with appropriate margins.

“This is an extreme example, but it shows you how difficult [establishing a diagnosis] can be,” Dr. Kelley said.

In a more recent study, researchers analyzed interobserver reproducibility in grading 179 DN cases among three observers who applied the 2018 World Health Organization grading criteria. The observers showed moderate to good agreement for most of the architectural features, except for criteria regarding focal continuous basal proliferation of melanocytes, density of non-nested junctional melanocytes, and presence of dyscohesive nests of intraepidermal melanocytes, whereas fair agreement was achieved for the cytological criteria. “So, it sounds to me like there was not a whole lot of agreement,” Dr. Kelley said.

An earlier single-center study titled “Clinicians Are From Mars and Pathologists Are From Venus” found that surgeons misunderstood the pathologist’s report 30% of the time.

In Dr. Kelly’s opinion, management of DNs will be successful if clinicians have a good working relationship with their dermatopathologists, if they biopsy to ensure an adequate, representative specimen, and if that they know what the terminology on the pathology report means and what actions to take. “The biopsy method matters,” he emphasized.

In a 14-year follow-up survey, investigators assessed DN management trends among 703 U.S. dermatologists. One key finding was that 69% of dermatologists in 2015 performed total removals when biopsying DN to achieve clear margins, compared with 86% in 2001.

A subsequent survey of 213 New England–based dermatologists found that the degree of clinical suspicion for melanoma was important in DN biopsy technique, with more respondents favoring shave biopsies for lesions with low suspicion and full-thickness biopsies for highly suspicious lesions.

“Misdiagnosis is more common for melanomas that have been assessed with punch and shave biopsies than with an excisional biopsy,” Dr. Kelley said. “I’m not too much of a stickler. I don’t require everyone to send me a giant excision, but I do want a representative sample.”

What about re-excision of DN considered to be mild or moderate? In 2015, members of the Pigmented Lesion Subcommittee of the Melanoma Prevention Working Group published a consensus statement on DN management recommendations for clinically atypical nevi/DN based on a review of published evidence. The subcommittee members concluded that mildly and moderately DN with clear margins do not need to be re-excised, and that mildly DN biopsied with positive histologic margins without clinical residual pigmentation may be safely observed rather than re-excised.

For moderately DN with positive histologic margins without clinically apparent residual pigmentation, the subcommittee members concluded that observation may be reasonable.

In his own informal analysis, Dr. Kelley compiled data from published studies he could find on DN management and divided them into two groups: the observation group, in which researchers from eight studies biopsied the DN lesion and watched the patients over time to see what happened, and the re-excision group, in which researchers from seven studies biopsied the DN lesion and subsequently re-excised it. There were about 1,500 patients in both groups. No deaths occurred in either group, he said, but 15 patients in the re-excision group developed a melanoma at the site of the original biopsy (1%), compared with 7 in the observation group (0.5%).

Six of seven melanomas in the observation group came from one article conducted at a VA clinic. In the study, 6 of 304 observed DN subsequently developed melanoma at the site of the lesion. “However, five of six that developed melanoma had an original biopsy that was a partial biopsy with grossly positive margins; I think that’s where the problem lies,” Dr. Kelley said at the meeting, which was hosted by Scripps MD Anderson Cancer Center. “All five grew lentigo maligna type melanoma, which we know can extend multiple millimeters beyond the clinically apparent lesion.”
