Lipoatrophic panniculitis in an adolescent.

Lipoatrophic panniculitis (LP) is a rare childhood panniculitis characterized by sclerotic, atrophic plaques on the extremities. We present a case of LP diagnosed during the inflammatory phase that was difficult to distinguish clinically from eosinophilic fasciitis. This report adds to the limited phenotypic spectrum of LP by differentiating the clinical features of disease activity from disease damage and highlighting the importance of biopsy in establishing a diagnosis.

Tender finger nodule.

A male in his twenties presented with a tender finger nodule that had been present for 3 months. Histopathological examination revealed a dermis with nodules of necrotic, athypical epithelaia cells with high nuclear to cytoplasmic ratios. Glandular formation was present with lumens lined by columnar epithelium, consistent with digital papillary adenocarcinoma. Digital papilary adenocarcinoma is a rare malignant adnexal tumor arising from sweat glands and requires further work-up.

Length-to-width ratio in Mohs defects: what is the golden rule?

A length-to-width ratio (LWR) of 3:1 for linear closures is often cited in the literature. However, there are limited studies evaluating this ratio in relation to various surgical sites. This study analyzes LWRs for 3318 patients undergoing Mohs micrographic surgery (MMS) and linear repair to identify the average LWRs stratified by patient age, anatomic location, gender, and surgeon. Average LWRs ranged between 2.89 and 3.82. The LWR for all anatomic sites averaged between 3:1 and 4:1, except for closures on the trunk. Locations with the highest LWR included the cheek, ear, and perioral sites.

Ablative fractional laser treatment of hypertrophic burn and traumatic scars: a systematic review of the literature.

Hypertrophic scars (HTS) following burns and other trauma and are associated with significant functional and psychosocial impairment. Ablative fractional lasers (AFLs) are increasingly being applied in the treatment of HTS supported by a rapidly expanding multidisciplinary base of literature. The multidisciplinary authors sought to evaluate existing literature, provide context and identify gaps, and make recommendations for a path forward. A systematic review was conducted to identify literature pertinent literature through September 2019. Retrospective cohort, randomized controlled trials, quasi-randomized controlled trials, observational prospective cohort, or case series with five or more subjects with hypertrophic scars incurred from burns and related trauma were considered. Twenty-two of the 23 evaluated studies documented statistically significant and/or meaningful qualitative improvements in nearly all outcome measures. Adverse events were generally infrequent and minor. Significant heterogeneity was observed among the studies included in this systematic review, precluding metaanalysis of pooled data. There is abundant existing literature on the use of AFLs in the management of HTS but study heterogeneity limits generalizability. Future studies should prioritize standardized protocols including assessments of function and quality of life.

Trainee Exposure and Education for Minimally Invasive Gender-Affirming Procedures.

Minimally invasive gender-affirming procedures (MIGAPs), which aim to align gender identity and expression for transgender and gender-nonbinary patients in a way that is safe, effective, and semipermanent or reversible, are gaining in popularity. This article assesses the current amount of trainee exposure in clinic and didactic sessions in core procedural specialties nationwide via survey study of program directors. Low exposure of residents and fellows to MIGAPs was observed overall and a lack of procedure-specific education. In an effort to provide excellent patient care, promote cultural humility, and improve patients' quality of life, further education regarding these procedures is necessary.

Tanning Salon Compliance Rates in States With Legislation to Protect Youth Access to UV Tanning.

Importance: The US Food and Drug Administration has classified tanning beds as carcinogenic. Most states have enacted legislation to prevent or create barriers for minors accessing tanning establishments. Determining tanning salon compliance with legislation would provide an indication of the influence of legislation at preventing exposure to the carcinogen in minors. Objectives: To investigate compliance rates in the 42 states and the District of Columbia with legislation restricting tanning bed use in minors and to identify differences in compliance based on population, regional location, salon ownership, age group being regulated, and time since the law was enacted. Design, Setting, and Participants: This investigation was a cross-sectional telephone survey conducted between February 1, 2015, and April 30, 2016, by callers posing as minors attempting to schedule a tanning appointment. The setting was tanning salons in the 42 states and the District of Columbia that currently have legislation restricting tanning bed use in minors. Included in the study were 427 tanning salons, 10 randomly selected from each state or territory with tanning legislation. Main Outcomes and Measures: Overall compliance of tanning salons with state tanning legislation and differences in compliance based on community population, regional location, independent vs chain tanning salon, age group being regulated, and time since the law was enacted. Results: Of the 427 tanning salons surveyed, overall noncompliance with state legislation was 37.2% (n = 159). There were more noncompliant tanning salons in rural locations (45.5%; 95% CI, 37.5%-53.7%; P = .009), southern regions of the United States (49.4%; 95% CI, 41.4%-57.4%; P = .001), independently owned salons (43.9%; 95% CI, 37.3%-50.6%; P = .003), states with younger age groups being regulated (53.5%; 95% CI, 45.7%-61.2%; P < .001), and states with more than one tanning regulation (50.0%; 95% CI, 42.0%-58.0%; P < .001). No difference was found based on time since the law was enacted. Conclusions and Relevance: Compliance with state legislation aimed at limiting tanning bed use among US minors is unsatisfactory, indicating that additional efforts to enforce the laws and education of the harmful effects of UV tanning are necessary, especially in rural, independently owned, and tanning salons in southern regions, which have decreased compliance rates.

Segmental neurofibromatosis with deep schwannoma.

An elderly patient presented with two clusters of asymptomatic fleshy and pedunculated papules. Biopsy of the papules was consistent with neurofibromas. Decades prior she had undergone a surgery for the excision of a large schwannoma. Given her lack of other neurofibromatosis findings, the patient was diagnosed with multisegmental neurofibromatosis (multi-SN) with deep schwannoma, a possible new phenotype of SN. Because this entity may be associated with internal malignancy, it is important to screen and educate these patients as well as to provide regular follow-up.
