Can dietary tweaks improve some skin diseases?
Since 1950, the terms “diet and skin” in the medical literature have markedly increased, said Vivian Shi, MD associate professor of dermatology at the University of Arkansas for Medical Sciences, Little Rock, who talked about nutritional approaches for select skin diseases at MedscapeLive’s Women’s and Pediatric Dermatology Seminar.
Myths abound, but some associations of diet with skin diseases hold water, and she said.
Acne
What’s known, Dr. Shi said, is that the prevalence of acne is substantially lower in non-Westernized countries, and that diets in those countries generally have a low glycemic load, which decreases IGF-1 insulinlike growth factor 1 (IGF-1) concentrations, an accepted risk factor for acne. The Western diet also includes the hormonal effects of cow’s milk products.
Whey protein, which is popular as a supplement, isn’t good for acne, Dr. Shi said. It takes a couple of hours to digest, while casein protein digests more slowly, over 5-7 hours. If casein protein isn’t acceptable, good alternatives to whey protein are hemp seed, plant protein blends (peas, seeds, berries), egg white, brown rice isolate, and soy isolate protein.
Dairy products increase IGF-1 levels, hormonal mediators that can make acne worse. In addition, industrial cow’s milk can contain anabolic steroids and growth factor, leading to sebogenesis, Dr. Shi said. As for the type of milk, skim milk tends to be the most acnegenic and associated with the highest blood levels of IGF-1.
Supplementing with omega-3 fatty acids and gamma-linolenic acid improved mild to moderate acne in a double-blind, controlled study. Researchers randomized 45 patients with mild to moderate acne to an omega-3 fatty acid group (2,000 mg of eicosapentaenoic acid and docosahexaenoic acid), a gamma-linolenic acid group (borage oil with 400 mg gamma-linolenic acid) or a control group. After 10 weeks in both treatment groups, there was a significant reduction in inflammatory and noninflammatory lesions.
Those with acne are more likely to be deficient in Vitamin D, research suggests. Researchers also found that among those who had vitamin D deficiency, supplementing with 1,000 IU daily for 2 months reduced inflammatory lesions by 35% after 8 weeks, compared with a 6% reduction in the control group.
Other research has found that those with a low serum zinc level had more severe acne and that 30-200 mg of zinc orally for 2-4 months reduced inflammatory acne. However, Dr. Shi cautioned that those taking zinc for more than 2 months also need a copper supplement, as zinc reduces the amount of copper absorbed by the body.
Dr. Shi’s “do’s” diet list for acne patients is a follows: Paleolithic and Mediterranean diets, omega-3 fatty acids, gamma-linolenic acids, Vitamin D, zinc, tubers, legumes, vegetables, fruits, and fish.
Unknowns, she said, include chocolate, caffeine, green tea, and high salt.
Hidradenitis suppurativa
Patents with HS who follow a Mediterranean diet most closely have less severe disease, research has found. In this study, those patients with HS with the lowest adherence had a Sartorius HS score of 59.38, while those who followed it the most closely had a score of 39 (of 80).
In another study, patients with HS reported the following foods as exacerbating HS: sweets, bread/pasta/rice, dairy, and high-fat foods. Alleviating foods included vegetables, fruit, chicken, and fish.
Dr. Shi’s dietary recommendations for patients with HS: Follow a Mediterranean diet, avoid high fat foods and highly processed foods, and focus on eating more vegetables, fresh fruit, corn-based cereal, white meat, and fish.
A retrospective study of patients with Hurley stage 1 and 2 found that oral zinc gluconate, 90 mg a day, combined with 2% topical triclosan twice a day, resulted in significantly decreased HS scores and nodules and improved quality of life after 3 months. Expect vitamin D deficiency, she added.
Lastly, Dr. Shi recommended, if necessary, “weight loss to reduce the inflammatory burden.”
Rosacea
Dietary triggers for rosacea are thought to include high-fat foods, dairy foods, spicy foods, hot drinks, cinnamon, and vanilla.
A population-based case-control study in China, which evaluated 1,347 rosacea patients and 1,290 healthy controls, found that a high intake of fatty foods positively correlated with erythematotelangiectatic rosacea (ETR) and phymatous rosacea. High-frequency dairy intake negatively correlated with ETR and papulopustular rosacea, which was a surprise, she said. And in this study, no significant correlations were found between sweets, coffee, and spicy foods. That goes against the traditional thinking, she said, but this was a Chinese cohort and their diet is probably vastly different than those in the United States.
Other rosacea triggers, Dr. Shi said, are niacin-containing foods such as turkey, chicken breast, crustaceans, dried Shiitake mushrooms, peanuts, tuna, and liver, as well as cold drinks, and formalin-containing foods (fish, squid, tofu, wet noodles).
As the field of nutrigenics – how genes affect how the body responds to food – evolves, more answers about the impact of diet on these diseases will be forthcoming, Dr. Shi said.
In an interactive panel discussion, she was asked if she talks about diet with all her patients with acne, rosacea, and HS, or just those not responding to traditional therapy.
“I think it’s an important conversation to have,” Dr. Shi responded. “When I’m done with the medication [instructions], I say: ‘There is something else you can do to augment what I just told you.’ ” That’s when she explains the dietary information. She also has a handout on diet and routinely refers patients for dietary counseling.

Diabetes devices may give children contact dermatitis
Devices that help children control their diabetes and lead fuller lives may also give them contact dermatitis, report the authors of a new study that calls for mandatory labeling of ingredients for allergy patch testing.
“A high share of patients showed positive reactions to isobornyl acrylate adhesive (IBOA) and/or their medical devices (insulin pumps or glucose devices),” the study authors write in Contact Dermatitis. “A third of patients showed positive reactions to benzoyl peroxide (BP),” used in adhesives.
“The presence of additional unidentified allergens cannot be excluded,” they add. “Overall, our experience once more highlights the importance of having access to a full description of the chemical composition of diabetes devices and related medical devices to efficiently manage patients (including children) who experience adverse skin reactions from such devices.”
Lead study author Catarina Alves da Silva, MD, of the department of dermatology and venereology of Aarhus (Denmark) University Hospital, and her colleagues conducted a retrospective study of 15 referred patients younger than 18 years who had type 1 diabetes. The children were patch tested in the university’s dermatology clinic between 2018 and 2020 in a study of skin reactions linked with diabetes devices.
Contact dermatitis from device-related allergens may be common
Many children in the study reacted to chemical compounds related to their devices.
- Of the 15 patients, seven showed positive patch test reactions to IBOA, and five showed positive reactions to BP.
- Ten children had positive patch test reactions to materials from glucose sensors and insulin pumps.
- Three showed positive reactions to adhesive remover wipes.
- Five reacted to .
Marcia Hogeling, MD, a pediatric dermatologist at UCLA Health in Santa Monica, Calif., told this news organization that she expected acrylates to cause problems but was surprised that BP caused positive patch test reactions.
BP is known to be a strong irritant but a weak allergen, the authors wrote.
“It was important to identify the allergens in these devices. Hopefully, this information will be used by manufacturers to create safer products for patients,” Dr. Hogeling, who was not involved in the study, said in an email.
Dr. Hogeling acknowledged that the small sample size is a weakness of the study, although she added that the findings may help providers select devices that do not contain their patients’ contact allergens.
Ryan J. McDonough, DO, a pediatric endocrinologist and the codirector of the Diabetes Center at Children’s Mercy Kansas City (Mo.), said in an email that, despite the small sample size, the study “highlights important device-related experiences of those living with type 1 diabetes that clinicians often encounter.
“We often spend considerable time aiding patients and their families in finding ways to mitigate the reactions,” he explained. “Having a broader understanding of these chemical compositions would help clinicians choose the right devices for their patients and prevent and treat these types of reactions.”
Dr. McDonough, who was not involved in the study, noted that the patients were in Denmark, and they were able to easily transition between insulin pumps and glucose monitoring devices.
“In the U.S., it is often more challenging to switch between devices, due to insurance-related concerns.
“The true rates of reaction in the broad type 1 diabetes population are difficult to assess,” Dr. McDonough said. “The study participants were drawn from patients referred to a dermatology clinic for evaluation of reaction. Many patients either don’t develop reactions or are treated for mild symptoms locally by their endocrinologists.
“This study should serve as a call to action for continued improvements in the transparency of the components that make up the devices and adhesives, and it can provide an opportunity to develop additional interventions to prevent these reactions,” he advised.
No information regarding funding for the study was provided. The authors, Dr. Hogeling, and Dr. McDonough reported no relevant financial relationships.

Widespread rash in toddler
This patient was given a diagnosis of Gianotti Crosti syndrome (GCS; also called infantile acrodermatitis of childhood), which is a self-resolving (often dramatic) dermatosis triggered by a viral infection or immunization. Patients with this syndrome develop papules, vesicles, and plaques on their face, hands, feet, and extremities a week (or more) after having a viral illness or receiving an immunization. In patients with darker skin types, lesions may appear purple to brown rather than bright red to red/orange. The syndrome typically occurs in children between the ages of 1 to 4 years, but almost all patients are under the age of 15.1 Scratching and sleep disturbance are common. The condition typically resolves on its own after 3 or 4 weeks.
Globally, the hepatitis B virus (HBV) is the most common cause of GCS.1 Other reported triggering viruses include hepatitis A and C, cytomegalovirus, Epstein-Barr virus, enteroviruses, HIV, parainfluenza viruses, parvoviruses, rubella, and COVID-19.2
Since the cause of this patient’s case of GCS was likely linked to a viral infection that produced the loose stools in a population with low-HBV risk, no further serologic testing was performed. Serologic testing may have been necessary if other infections, disease risks, or symptoms were identified. To relieve itching, topical triamcinolone 0.1% cream was prescribed for use once to twice daily on the extremities and hydrocortisone 1% cream was prescribed once to twice daily for use on the child’s face. At the 6-week follow-up visit, the lesions had resolved; light pink discoloration remained but was expected to further fade. In patients with darker skin, post-inflammatory hyperpigmentation may take several months to resolve.

At the 6-week follow-up visit, the lesions had resolved; light pink discoloration remained but was expected to further fade. In patients with darker skin, post-inflammatory hyperpigmentation may take several months to resolve.

No more ‘escape hatch’: Post Roe, new worries about meds linked to birth defects
As states ban or limit abortion in the wake of the demise of Roe v. Wade, physicians are turning their attention to widely-used drugs that can cause birth defects. At issue: Should these drugs still be prescribed to women of childbearing age if they don’t have the option of terminating their pregnancies?
“Doctors are going to understandably be terrified that a patient may become pregnant using a teratogen that they have prescribed,” said University of Pittsburgh rheumatologist Mehret Birru Talabi, MD, PhD, who works in a state where the future of abortion rights is uncertain. “While this was a feared outcome before Roe v. Wade was overturned, abortion provided an escape hatch by which women could avoid having to continue a pregnancy and potentially raise a child with congenital anomalies. I believe that prescribing is going to become much more defensive and conservative. Some clinicians may choose not to prescribe these medications to patients who have childbearing potential, even if they don’t have much risk for pregnancy.”
Other physicians expressed similar concerns in interviews. Duke University, Durham, N.C., rheumatologist Megan E. B. Clowse, MD, MPH, fears that physicians will be wary of prescribing a variety of medications – including new ones for which there are few pregnancy data – if abortion is unavailable. “Women who receive these new or teratogenic medications will likely lose their reproductive autonomy and be forced to choose between having sexual relationships with men, obtaining procedures that make them permanently sterile, or using contraception that may cause intolerable side effects,” she said. “I am very concerned that young women with rheumatic disease will now be left with active disease resulting in joint damage and renal failure.”
Abortion is now banned in at least six states, according to The New York Times. That number may rise to 16 as more restrictions become law. Another five states aren’t expected to ban abortion soon but have implemented gestational age limits on abortion or are expected to adopt them. In another nine states, courts or lawmakers will decide whether abortion remains legal.
Only 20 states and the District of Columbia have firm abortion protections in place.
Numerous drugs are considered teratogens, which means they may cause birth defects. Thalidomide is the most infamous, but there are many more, including several used in rheumatology, dermatology, and gastroenterology. Among the most widely used teratogenic medications are the acne drugs isotretinoin and methotrexate, which are used to treat a variety of conditions, such as cancer, rheumatoid arthritis, and psoriasis.
Dr. Clowse, who helps manage an industry-supported website devoted to reproductive care for women with lupus (www.LupusPregnancy.org), noted that several drugs linked to birth defects and pregnancy loss are commonly prescribed in rheumatology.
“Methotrexate is the most common medication and has been the cornerstone of rheumatoid arthritis [treatment] for at least two decades,” she said. “Mycophenolate is our best medication to treat lupus nephritis, which is inflammation in the kidneys caused by lupus. This is a common complication for young women with lupus, and all of our guideline-recommended treatment regimens include a medication that causes pregnancy loss and birth defects, either mycophenolate or cyclophosphamide.”
Rheumatologists also prescribe a large number of new drugs for which there are few data about pregnancy risks. “It typically takes about two decades to have sufficient data about the safety of our medications,” she said.
Reflecting the sensitivity of the topic, Dr. Clowse made clear that her opinions don’t represent the views of her institution. She works in North Carolina, where the fate of abortion rights is uncertain, according to The New York Times.
What about alternatives? “The short answer is that some of these medications work really well and sometimes much better than the nonteratogenic alternatives,” said Dr. Birru Talabi. “I’m worried about methotrexate. It has been used to induce abortions but is primarily used in the United States as a highly effective treatment for cancer as well as a myriad of rheumatic diseases. If legislators try to restrict access to methotrexate, we may see increasing disability and even death among people who need this medication but cannot access it.”
Rheumatologists aren’t the only physicians who are worrying about the fates of their patients in a new era of abortion restrictions. Gastroenterologist Sunanda Kane, MD, MSPH, of the Mayo Clinic, Rochester, Minn., said several teratogenic medications are used in her field to treat constipation, viral hepatitis, and inflammatory bowel disease.
“When treating women of childbearing age, there are usually alternatives. If we do prescribe a medication with a high teratogenic potential, we counsel and document that we have discussed two forms of birth control to avoid pregnancy. We usually do not prescribe a drug with teratogenic potential with the ‘out’ being an abortion if a pregnancy does occur,” she said. However, “if abortion is not even on the table as an option, we may be much less likely to prescribe these medications. This will be particularly true in patients who clearly do not have the means to travel to have an abortion in any situation.”
Abortion is expected to remain legal in Minnesota, where Dr. Kane practices, but it may be restricted or banned in nearby Wisconsin, depending on the state legislature. None of her patients have had abortions after becoming pregnant while taking the medications, she said, although she “did have a patient who because of her religious faith did not have an abortion after exposure and ended up with a stillbirth.”
The crackdown on abortion won’t just pose risks to patients who take potentially dangerous medications, physicians said. Dr. Kane said pregnancy itself is a significant risk for patients with “very active, uncontrolled gastrointestinal conditions where a pregnancy could be harmful to the mother’s health or result in offspring that are very unhealthy.” These include decompensated cirrhosis, uncontrolled Crohn’s disease or ulcerative colitis, refractory gastroparesis, uncontrolled celiac sprue, and chronic pancreatitis, she said.
“There have been times when after shared decisionmaking, a patient with very active inflammatory bowel disease has decided to terminate the pregnancy because of her own ongoing health issues,” she said. “Not having this option will potentially lead to disastrous results.”
Dr. Clowse, the Duke University rheumatologist, echoed Dr. Kane’s concerns about women who are too sick to bear children. “The removal of abortion rights puts the lives and quality of life for women with rheumatic disease at risk. For patients with lupus and other systemic rheumatic disease, pregnancy can be medically catastrophic, leading to permanent harm and even death to the woman and her offspring. I am worried that women in these conditions will die without lifesaving pregnancy terminations, due to worries about the legal consequences for their physicians.”
The U.S. Supreme Court’s ruling that overturned Roe v. Wade has also raised the prospect that the court could ultimately allow birth control to be restricted or outlawed.
While the ruling states that “nothing in this opinion should be understood to cast doubt on precedents that do not concern abortion,” Justice Clarence Thomas wrote a concurrence in which he said that the court should reconsider a 1960s ruling that forbids the banning of contraceptives. Republicans have dismissed concerns about bans being allowed, although Democrats, including the president and vice president, starkly warn that they could happen.
“If we as providers have to be concerned that there will be an unplanned pregnancy because of the lack of access to contraception,” Dr. Kane said, “this will have significant downstream consequences to the kind of care we can provide and might just drive some providers to not give care to female patients at all given this concern.”

Study finds higher risk of skin cancer after childhood organ transplant
A large study showing an increased risk of keratinocyte carcinoma (KC) in children who receive a solid-organ transplant highlights the need for early education about risk reduction and more research to determine optimal timing for screening, say an investigator and two dermatologists with expertise in transplant-related skin issues.
The increased incidence of KC in pediatric transplant recipients is “really high, so we definitely know there’s risk there,” just as there is for adult recipients of solid-organ transplants, said Cathryn Sibbald, MD, MSc, a dermatologist at the Hospital for Sick Children in Toronto and coauthor of a research letter published in June in JAMA Dermatology.
For their study, Dr. Sibbald and her coinvestigators turned to the Ontario Health Insurance plan database, which covers health care for Canadian citizens and qualified residents in the province. They identified 951 patients younger than the age of 18 who received a solid-organ transplant between 1991 and 2004 at an Ontario hospital
They then used a validated health insurance claims–based algorithm to identify diagnoses of KC for the transplant recipients and for more than 5 million age-matched controls. KC, including squamous and basal cell carcinoma, is the most prevalent skin cancer for people who have had a solid-organ transplant.
Fifteen posttransplant KCs (10 patients, 1.1%) were reported a mean of 13.1 years after transplant, with none reported in the first 4 years. The mean age at transplant was 7.8 years, and the mean age at KC diagnosis was 25.2 years. Kidney transplants were the most common (42.1% of transplantations). Most of the transplants recipients (eight patients) who developed KC had kidney transplantation, and most of them had functional graft at the time of KC diagnosis.
Researchers found an increased incidence of KC compared with that of the general population (standardized incidence ratio, 9.09; 95% confidence interval, 5.48-15.08). And the risk for KC increased with time since transplant, with adjusted hazard ratios for KC of 3.63 (95% CI, 0.51-25.77) for 1-5 years, 5.14 (95% CI, 1.28-20.55) for 5-10 years, and 4.80 (95% CI, 2.29-10.08) for 10 years or more, compared with the control population.
Several years ago, another research team performed a similar population-based cohort study of adult transplant recipients in Ontario and found a 6.6-times increased risk of KC in transplant recipients compared with the general population.
Sun protection and skin cancer screening
In commenting on the study, Sarah Arron, MD, PhD, a San Francisco Bay area dermatologist and immediate past president of the International Immunosuppression and Transplant Skin Cancer Collaborative (www.itscc.org), said she feels “reassured” that young transplant patients tend not to develop the skin cancer until young adulthood.
A ”large study like this is important because the overall rate of KC is low in this age group,” she noted.
The findings “suggest that we can focus our efforts on prevention during childhood, with sun protection and skin cancer education,” she said. “Then, as these children move into adulthood, we can begin screening with skin examinations. Of course, [any child] with a skin lesion or mole that concerns their parents or transplant team should be referred to dermatology for evaluation.”
Pediatric transplant recipients and their parents are most interested in learning about skin cancer prevention either before or immediately after transplantation, according to a survey by other researchers.
Intervention studies needed
The increased risk of KC probably stems largely from immunosuppression, said Dr. Sibbald in an interview. “We know [this is the case] in the older population, and it’s likely true in the younger population as well that it’s one of the primary drivers,” she said.
More research to extensively analyze risk factors should come next, she said. This includes “the granularity of what [immunosuppressants and other] medications are received, and at what dose and for what periods of time, so we can calculate cumulative exposure and its relation to risk,” she said.
Kristin Bibee, MD, PhD, assistant professor of dermatology at Johns Hopkins University in Baltimore, said she’d like to see further studies “evaluate appropriate interventions, like sun-protective behavior in childhood and adolescence or immunosuppression modulation, to prevent malignancy development.”
The optimal time and intensity of screening for young transplant recipients must still be determined, both Dr. Bibee and Dr. Arron said. Patients deemed through further research to be at higher risk may need earlier and/or more intensive surveillance.
The role of race in skin cancer risk in this population is “one question the study leaves open,” said Dr. Arron. U.S. studies have shown that among adult transplant recipients White patients are “at highest risk for the ultraviolet-associated melanoma and squamous cell carcinoma, followed by Asian and Latino patients. African Americans have had the lowest risk, but some still developed skin cancer after transplant,” she said.
Prior studies of cancer in pediatric transplant recipients have reported primarily on internal malignant neoplasms, with limited data on KC, Dr. Sibbald and coauthors wrote. It is possible the incidence of KS is underestimated in the new study because of “undiagnosed or unreported KCs,” they noted.
The new study was funded by a grant from the Pediatric Dermatology Research Alliance and a Hospital for Sick Children grant. In disclosures, Dr. Sibbald reported to JAMA Dermatology receiving grants from the alliance and from Paediatric Consultants Partnership during the conduct of the study. Dr. Arron and Dr. Bibee both said they have no disclosures relevant to the study and its content.

The increased incidence of KC in pediatric transplant recipients is “really high, so we definitely know there’s risk there,” just as there is for adult recipients of solid-organ transplants, said Cathryn Sibbald, MD, MSc, a dermatologist at the Hospital for Sick Children in Toronto and coauthor of a research letter published in June in JAMA Dermatology.
For their study, Dr. Sibbald and her coinvestigators turned to the Ontario Health Insurance plan database, which covers health care for Canadian citizens and qualified residents in the province. They identified 951 patients younger than the age of 18 who received a solid-organ transplant between 1991 and 2004 at an Ontario hospital
They then used a validated health insurance claims–based algorithm to identify diagnoses of KC for the transplant recipients and for more than 5 million age-matched controls. KC, including squamous and basal cell carcinoma, is the most prevalent skin cancer for people who have had a solid-organ transplant.
Fifteen posttransplant KCs (10 patients, 1.1%) were reported a mean of 13.1 years after transplant, with none reported in the first 4 years. The mean age at transplant was 7.8 years, and the mean age at KC diagnosis was 25.2 years. Kidney transplants were the most common (42.1% of transplantations). Most of the transplants recipients (eight patients) who developed KC had kidney transplantation, and most of them had functional graft at the time of KC diagnosis.
Researchers found an increased incidence of KC compared with that of the general population (standardized incidence ratio, 9.09; 95% confidence interval, 5.48-15.08). And the risk for KC increased with time since transplant, with adjusted hazard ratios for KC of 3.63 (95% CI, 0.51-25.77) for 1-5 years, 5.14 (95% CI, 1.28-20.55) for 5-10 years, and 4.80 (95% CI, 2.29-10.08) for 10 years or more, compared with the control population.
Several years ago, another research team performed a similar population-based cohort study of adult transplant recipients in Ontario and found a 6.6-times increased risk of KC in transplant recipients compared with the general population.
Sun protection and skin cancer screening
In commenting on the study, Sarah Arron, MD, PhD, a San Francisco Bay area dermatologist and immediate past president of the International Immunosuppression and Transplant Skin Cancer Collaborative (www.itscc.org), said she feels “reassured” that young transplant patients tend not to develop the skin cancer until young adulthood.
A ”large study like this is important because the overall rate of KC is low in this age group,” she noted.
The findings “suggest that we can focus our efforts on prevention during childhood, with sun protection and skin cancer education,” she said. “Then, as these children move into adulthood, we can begin screening with skin examinations. Of course, [any child] with a skin lesion or mole that concerns their parents or transplant team should be referred to dermatology for evaluation.”
Pediatric transplant recipients and their parents are most interested in learning about skin cancer prevention either before or immediately after transplantation, according to a survey by other researchers.
Intervention studies needed
The increased risk of KC probably stems largely from immunosuppression, said Dr. Sibbald in an interview. “We know [this is the case] in the older population, and it’s likely true in the younger population as well that it’s one of the primary drivers,” she said.
More research to extensively analyze risk factors should come next, she said. This includes “the granularity of what [immunosuppressants and other] medications are received, and at what dose and for what periods of time, so we can calculate cumulative exposure and its relation to risk,” she said.
Kristin Bibee, MD, PhD, assistant professor of dermatology at Johns Hopkins University in Baltimore, said she’d like to see further studies “evaluate appropriate interventions, like sun-protective behavior in childhood and adolescence or immunosuppression modulation, to prevent malignancy development.”
The optimal time and intensity of screening for young transplant recipients must still be determined, both Dr. Bibee and Dr. Arron said. Patients deemed through further research to be at higher risk may need earlier and/or more intensive surveillance.
The role of race in skin cancer risk in this population is “one question the study leaves open,” said Dr. Arron. U.S. studies have shown that among adult transplant recipients White patients are “at highest risk for the ultraviolet-associated melanoma and squamous cell carcinoma, followed by Asian and Latino patients. African Americans have had the lowest risk, but some still developed skin cancer after transplant,” she said.
Prior studies of cancer in pediatric transplant recipients have reported primarily on internal malignant neoplasms, with limited data on KC, Dr. Sibbald and coauthors wrote. It is possible the incidence of KS is underestimated in the new study because of “undiagnosed or unreported KCs,” they noted.
The new study was funded by a grant from the Pediatric Dermatology Research Alliance and a Hospital for Sick Children grant. In disclosures, Dr. Sibbald reported to JAMA Dermatology receiving grants from the alliance and from Paediatric Consultants Partnership during the conduct of the study. Dr. Arron and Dr. Bibee both said they have no disclosures relevant to the study and its content.

Introduce allergens early, say French allergists
Although in many cases, food-allergen tolerance can be achieved with oral immunotherapy, primary prevention of food allergies remains crucial, according to the French Society of Allergology. In new recommendations that were presented at a session of the Congress of French Pediatric Societies, the academic society advocated early introduction of allergens for all children, starting at 4 months of age.
The latest prevention data from two major studies, LEAP and EAT, have prompted European and French experts to rethink their stance on food diversification. The new French proposals were recently published under the coordination of Dominique Sabouraud-Leclerc, MD, pediatrics department, Reims (France) University Hospital, on behalf of the Food Allergy Working Group of the French Society of Allergology.
For all newborns, regardless of whether they have a history of atopic or nonatopic dermatitis, food diversification is now recommended from 4 months of age instead of 6 months, as was previously recommended. If the child does not develop atopic dermatitis or develops only a mild form, peanuts, eggs, and nuts may be introduced at home.
However, if the child experiences severe atopic dermatitis, an allergy testing panel for peanuts, nuts, eggs, and cow’s milk proteins should be performed. An oral food challenge may be conducted at the allergist’s discretion.
Regarding peanuts, the working group proposed introducing a purée in the form of either a mixture of peanuts/hazelnuts/cashew nuts (1 level teaspoon five times a week; 2 g of protein/food per week) or a 100% peanut paste (1 scant teaspoon four times a week; 2 g of peanut protein/week). If the family is worried, the allergist can suggest monitoring the child in the clinic waiting room for 30 minutes after the first dose.
“We shouldn’t delay the introduction of the primary allergens anymore, regardless of whether children are at risk for a food allergy, and particularly a peanut allergy,” explained Stéphanie Lejeune, MD, pediatric pulmonologist and allergist at Lille (France) Regional University Hospital, who presented these new findings at the congress. “In fact, if we only target at-risk children, we overlook children with no family history who will nevertheless develop food allergies. The idea is to introduce everything, especially peanuts, between 4 and 6 months of age and to no longer do so gradually, one food after another, as was being done until now, beginning at 6 months and over. We must give priority to regularity over quantity.”
Although this approach is based on clinical trials, no real-life data are currently available.
LEAP and EAT studies support early introduction of peanuts
A study from 2021 summed up the risk factors for peanut allergy. About 61% of infants (4-11 months) had atopic dermatitis, 18% had a food allergy, 62% had a first-degree relative with a peanut allergy, and 11% had a confirmed peanut allergy. The risk of peanut allergy increased with age and severe eczema.
In 2015, the LEAP study, which was conducted in the United Kingdom with 640 infants aged 4-11 months who had risk factors for peanut allergy, revolutionized peanut-allergy primary prevention. Regardless of whether the children were sensitized or not, the number of children who developed a peanut allergy was systematically lower in the group that ingested the allergen in comparison with the “avoidance” group.
Additionally, the LEAP-ON study showed that protection against peanut allergy persisted for 12 months after cessation of consumption between ages 5 and 6 years among children who had consumed peanuts previously.
Early diversification in the general population was investigated in the EAT study, which involved 1303 breastfed infants. Of these infants, 24% had atopic dermatitis (median SCORAD score, 7.5). They were divided into two arms: avoidance and breast feeding until 6 months (standard introduction) or early introduction at 3 months (boiled egg, milk, peanuts, sesame, white fish, wheat, 2 g of protein twice a week). In the per-protocol analysis, there were 13 cases of peanut allergy in the standard introduction group; there were no cases in the early introduction group.

Study provides consensus on lab monitoring during isotretinoin therapy
For generally ideally within a month prior to the start of treatment, and a second time at peak dose.
Other tests such as complete blood cell counts and basic metabolic panels as well as specific laboratory tests such as LDL and HDL cholesterol should not be routinely monitored.
Those are key conclusions from a Delphi consensus study that included 22 acne experts from five continents and was published in JAMA Dermatology.
“Our results apply findings from recent literature and are in accordance with recent studies that have recommended against excessive laboratory monitoring,” senior corresponding author Arash Mostaghimi, MD, MPA, MPH, and coauthors wrote. “For instance, several studies in both teenagers and adults have shown that routine complete blood cell count laboratory tests are unnecessary without suspicion of an underlying abnormality and that rare abnormalities, if present, either resolved or remained stable without clinical impact on treatment. Likewise, liver function tests and lipid panels ordered at baseline and after 2 months of therapy were deemed sufficient if the clinical context and results do not suggest potential abnormalities.”
The authors also noted that, while published acne management guidelines exist, such as the American Academy of Dermatology work group guidelines and the National Institute for Health and Care Excellence guideline, “the specific recommendations surrounding laboratory monitoring frequency are nonstandardized and often nonspecific.”
To establish a consensus for isotretinoin laboratory monitoring, Dr. Mostaghimi, of the department of dermatology at Brigham and Women’s Hospital, Boston, and colleagues used a Delphi process to administer four rounds of electronic surveys to 22 board-certified dermatologists between 2021 and 2022. The primary outcome measured was whether participants could reach consensus on key isotretinoin lab monitoring parameters. Responses that failed to reach a threshold of 70% indicated no consensus.
The surveyed dermatologists had been in practice for a mean of 23.7 years, 54.5% were female, 54.5% practiced in an academic setting, and 63.9% were based in North America. They reached consensus for checking ALT within a month prior to initiation (89.5%) and at peak dose (89.5%), but not checking monthly (76.2%) or after completing treatment (73.7%). They also reached consensus on checking triglycerides within a month prior to initiation (89.5%) and at peak dose (78.9%) but not to check monthly (84.2%) or after completing treatment (73.7%).
Meanwhile, consensus was achieved for not checking complete blood cell count or basic metabolic panel parameters at any point during isotretinoin treatment (all > 70%), as well as not checking gamma-glutamyl transferase (78.9%), bilirubin (81.0%), albumin (72.7%), total protein (72.7%), LDL cholesterol (73.7%), HDL cholesterol (73.7%), or C-reactive protein (77.3%).
“Additional research is required to determine best practices for laboratory measures that did not reach consensus,” the authors wrote. The study results “are intended to guide appropriate clinical decision-making,” they added. “Although our recommendations cannot replace clinical judgment based on the unique circumstances of individual patients, we believe they provide a framework for management of a typical, otherwise healthy patient being treated with isotretinoin for acne. More routine monitoring, or reduced monitoring, should be considered on a case-by-case basis accounting for the unique medical history, circumstances, and baseline abnormalities, if present, of each patient.”
“Practicing dermatologists, including myself, routinely check blood laboratory values during isotretinoin treatment,” said Lawrence J. Green, MD, clinical professor of dermatology at George Washington University, Washington, who was asked to comment on the study. “Even though just a small number of U.S.-based and international acne researchers were involved in this Delphi consensus statement, this article still makes us practicing clinicians feel more comfortable in checking fewer lab chemistries and also less frequently checking labs when we use isotretinoin.
“That said, I don’t think most of us are ready, because of legal reasons, to do that infrequent monitoring” during isotretinoin therapy, Dr. Green added. “I think most dermatologists do not routinely perform CBCs anymore, but we still feel obligated to check triglycerides and liver function more frequently” than recommended in the new study.

Bleeding arm lesion
Pyogenic granulomas (PGs), also called lobular capillary hemangiomas, manifest as friable, moist or glistening, papules. PGs are a benign vascular proliferation. They often have a collarette, which is subtle in this lesion, and they bleed with minimal trauma. They are commonly seen on the gingiva during pregnancy, the umbilical area in newborns, or at sites of trauma.
Since PGs often occur during pregnancy, it’s been suggested that their development is related to hormonal changes.1 It’s also been suggested that PGs are the result of an abnormal hypertrophic healing response, as they can occur in men, infants (at the umbilical stump), and even within blood vessels.1
Although benign and painless, PGs are usually hard to ignore due to their raised appearance, tendency to bleed, and the low likelihood that they will resolve on their own. There are multiple physical treatment options available, including excision with primary closure, curettage followed by electrodessication, laser treatment, and cryosurgery. Topical therapies include timolol (a beta-blocker that has been used successfully with congenital hemangiomas), imiquimod, and trichloroacetic acid.1 These topical medications do not require any anesthetic, which may make them an appealing option for children. Unfortunately, topical medications require multiple applications over a period of 2 or more weeks.
In this case, the lesion was shaved off and sent out to pathology to rule out amelanotic melanoma. The pathology for this patient confirmed PG. Immediately following the lesion’s removal, the physician performed 2 cycles of curettage and electrodessication. Thus, the patient’s treatment was completed on the same day as her evaluation.

In this case, the lesion was shaved off and sent out to pathology to rule out amelanotic melanoma. The pathology for this patient confirmed PG. Immediately following the lesion’s removal, the physician performed 2 cycles of curettage and electrodessication. Thus, the patient’s treatment was completed on the same day as her evaluation.

Pyogenic granulomas (PGs), also called lobular capillary hemangiomas, manifest as friable, moist or glistening, papules. PGs are a benign vascular proliferation. They often have a collarette, which is subtle in this lesion, and they bleed with minimal trauma. They are commonly seen on the gingiva during pregnancy, the umbilical area in newborns, or at sites of trauma.
Since PGs often occur during pregnancy, it’s been suggested that their development is related to hormonal changes.1 It’s also been suggested that PGs are the result of an abnormal hypertrophic healing response, as they can occur in men, infants (at the umbilical stump), and even within blood vessels.1
Although benign and painless, PGs are usually hard to ignore due to their raised appearance, tendency to bleed, and the low likelihood that they will resolve on their own. There are multiple physical treatment options available, including excision with primary closure, curettage followed by electrodessication, laser treatment, and cryosurgery. Topical therapies include timolol (a beta-blocker that has been used successfully with congenital hemangiomas), imiquimod, and trichloroacetic acid.1 These topical medications do not require any anesthetic, which may make them an appealing option for children. Unfortunately, topical medications require multiple applications over a period of 2 or more weeks.

Adolescent female with rash on the arms and posterior legs
Erythema annulare centrifugum
A thorough body examination failed to reveal any other rashes or lesions suggestive of a fungal infection. A blood count and urinalysis were within normal limits. She had no lymphadenopathy or hepatosplenomegaly. A potassium hydroxide analysis of skin scrapings was negative for fungal elements. Punch biopsy of the skin on the left arm revealed focal intermittent parakeratosis, mildly acanthotic and spongiotic epidermis, and a tight superficial perivascular chronic dermatitis consisting of lymphocytes and histiocytes (Figures). Given these findings, a diagnosis of erythema annulare centrifugum (EAC) was rendered.
EAC is a rare, reactive skin rash characterized by redness (erythema) and ring-shaped lesions (annulare) that slowly spread from the center (centrifugum). The lesions present with a characteristic trailing scale on the inner border of the erythematous ring. Lesions may be asymptomatic or mildly pruritic and commonly involve the trunk, buttocks, hips, and upper legs. It is important to note that its duration is highly variable, ranging from weeks to decades, with most cases persisting for 9 months. EAC typically affects young or middle-aged adults but can occur at any age.
Although the etiology of EAC is unknown, it is believed to be a hypersensitivity reaction to a foreign antigen. Cutaneous fungal infections are commonly reported as triggers as well as other viral infections, medications, malignancy, underlying systemic disease, and certain foods. Treatment depends on the underlying condition and removing the implicated agent. However, most cases of EAC are idiopathic and self-limiting. It is possible that our patient’s prior history of tinea capitis could have triggered the skin lesions suggestive of EAC, but interestingly, these lesions did not go away after the fungal infection was cleared and have continued to recur. For patients with refractory lesions or treatment of patients without an identifiable cause, the use of oral antimicrobials has been proposed. Medications such as azithromycin, erythromycin, fluconazole, and metronidazole have been reported to be helpful in some patients with refractory EAC. Our patient wanted to continue topical treatment with betamethasone as needed and may consider antimicrobial therapy if the lesions continue to recur.
Tinea corporis refers to a superficial fungal infection of the skin. It may present as one or more asymmetrical, annular, pruritic plaques with a raised scaly leading edge rather than the trailing scale seen with EAC. Diagnosis is made by KOH examination of skin scrapings. Common risk factors include close contact with an infected person or animal, warm, moist environments, sharing personal items, and prolonged use of systemic corticosteroids. Our patient’s KOH analysis of skin scrapings was negative for fungal elements.
Erythema marginatum is a rare skin rash commonly seen with acute rheumatic fever secondary to streptococcal infection. It presents as annular erythematous lesions on the trunk and proximal extremities that are exacerbated by heat. It is often associated with active carditis related to rheumatic fever. This self-limited rash usually resolves in 2-3 days. Our patient was asymptomatic without involvement of other organs.
Like EAC, granuloma annulare is a benign chronic skin condition that presents with ring-shaped lesions. Its etiology is unknown, and lesions may be asymptomatic or mildly pruritic. Localized granuloma annulare typically presents as reddish-brown papules or plaques on the fingers, hands, elbows, dorsal feet, or ankles. The distinguishing feature of granuloma annulare from other annular lesions is its absence of scale.
Urticaria multiforme is an allergic hypersensitivity reaction commonly linked to viral infections, medications, and immunizations. Clinical features include blanchable annular/polycyclic lesions with a central purplish or dusky hue. Diagnostic pearls include the presence of pruritus, dermatographism, and individual lesions that resolve within 24 hours, all of which were not found in our patient’s case.

Physical exam was notable for scattered, pink, annular plaques with central clearing, faint brownish pigmentation, and fine scale.
Basal cell carcinoma
THE COMPARISON
A Nodular basal cell carcinoma (BCC) with a pearly rolled border, central pigmentation, and telangiectasia on the forehead of an 80-year-old Hispanic woman (light skin tone).
B Nodular BCC on the cheek of a 64-year-old Black man. The dark nonhealing ulcer had a subtle, pearly, rolled border and no visible telangiectasia.
Basal cell carcinoma (BCC) is most prevalent in individuals with lighter skin tones and rarely affects those with darker skin tones. Unfortunately, the lower incidence and lack of surveillance frequently result in a delayed diagnosis and increased morbidity for the skin of color population.1
Epidemiology
BCC is the most common skin cancer in White, Asian, and Hispanic individuals and the second most common in Black individuals. Squamous cell carcinoma is the most common skin cancer in Black individuals.2
Although BCCs are rare in individuals with darker skin tones, they most often develop in sun-exposed areas of the head and neck region.1 In one study in an academic urban medical center, BCCs were more likely to occur in lightly pigmented vs darkly pigmented Black individuals.3
Key clinical features in people with darker skin tones
The classic BCC manifestation of a pearly papule with rolled borders and telangiectasia may not be seen in the skin of color population, especially among those with darker skin tones.4 In patient A, a Hispanic woman, these features are present along with hyperpigmentation. More than 50% of BCCs are pigmented in patients with skin of color vs only 5% in White individuals. 5-7 The incidence of a pigmented BCC is twice as frequent in Hispanic individuals (FIGURE, A) as in non- Hispanic White individuals.7 Any skin cancer can present with ulcerations. So, while this is not specific to BCC, it is a reason to consider biopsy.
Worth noting
Pigmented BCC can mimic melanoma clinically and even when viewed with a dermatoscope, but such a suspicious lesion should prompt the clinician to perform a biopsy regardless of the type of suspected cancer. With experience and training, however, physicians can use dermoscopy to help make this distinction.
Note that skin of color is found in a heterogeneous population with a spectrum of skin tones and genetic/ethnic variability. In my practice in San Antonio (RPU), BCC is uncommon in Black patients and relatively common in Hispanic patients with lighter skin tones (FIGURE, A).
There is speculation that a lower incidence of BCC in the skin of color population leads to a low index of suspicion, which contributes to delayed diagnoses with poorer outcomes.1 There are no firm data to support this because the rare occurrence of BCC in darker skin tones makes this a challenge to study.
Health disparity highlight
In general, barriers to health care include poverty, lack of education, lack of health insurance, and systemic racism. One study on keratinocyte skin cancers including BCC and squamous cell carcinoma found that these cancers were more costly to treat and required more health care resources, such as ambulatory visits and medication costs, in non-Hispanic Black and Hispanic White patients compared to non-Hispanic White patients.8
Final thoughts
Efforts are needed to achieve health equity through education of patients and health care providers about the appearance of BCC in skin of color with the goal of earlier diagnosis. Any nonhealing ulcer on the skin (FIGURE, B) should prompt consideration of skin cancer—regardless of skin color.
