Daffodils (Narcissus species) are the most common cause of irritant contact dermatitis among florists. Calcium oxalate crystals contained in the sap of the daffodil plants lead to irritant contact dermatitis on the skin. Daffodil rash commonly presents with fissuring, scaling, and erythema of the fingertips, hands, and forearms. The best preventative measure is to wear appropriate protective gloves and clothing.

Transferring from one residency program to another is uncommon but not impossible. There are many reasons why a trainee may wish to pursue transferring training programs-to be closer to family, to leave a stressful environment, or to pursue a different specialty. The transfer applicant must navigate the process without structured support. There can be downsides as well as great rewards to successfully transferring residency training programs.

Fibroepithelioma of Pinkus (FeP) is a rare skin tumor with a clinical presentation similar to benign neoplasms such as acrochordons and seborrheic keratoses. Our study analyzed if there is an association between FeP and internal tumors, specifically gastrointestinal tract tumors. We retrospectively reviewed the medical records of patients with FeP for other tumors throughout their lives until 2020. Although the quality of documentation for each patient may have differed, this study suggests that the presence of FeP does not indicate the presence of gastrointestinal tract tumors, and there is no need for altered cancer screening recommendations for those with FeP...

Pemphigus is an autoimmune blistering disease that can negatively affect patients' lives. Assessing the impact of treatment from a patient's perspective using outcome assessment measures is important and relevant in trials of new pemphigus treatments including rituximab (RTX). We sought to evaluate the effect of RTX on health-related quality of life (HRQOL) in pemphigus patients and peruse the clinical relevance of the patient-reported outcomes. A retrospective cross-sectional study was designed with 96 pemphigus patients given RTX either 3 months earlier or in the last 2 weeks...

Dermatology residency continues to be one of the most competitive specialties, with a match rate of 84.7% in 2019. We surveyed 475 dermatology applicants who applied to the Mayo Clinic in Scottsdale, Arizona, during the 2018-2019 application cycle and 629 dermatology applicants who applied to the Mayo Clinic in Scottsdale; Rochester, Minnesota; and Jacksonville, Florida, during the 2019-2020 application cycle. The initial survey obtained application and demographic information. The follow-up survey obtained match data...

Epidermal growth factor receptor (EGFR) inhibitors cause numerous cutaneous adverse events (AEs), including papulopustular eruptions, paronychia, acral fissures, xerosis, alopecia, and trichomegaly. Symmetrical drug-related intertriginous and flexural exanthema (SDRIFE) is a cutaneous reaction that has been uncommonly reported in association with EGFR inhibitors, though the optimal management strategy for this condition is unknown. We present 2 cases of SDRIFE secondary to EGFR inhibitor therapy in which the EGFR inhibitor was successfully continued while topical therapy was administered for effective control of symptoms...

Hereditary alpha tryptasemia (HaT) is a recently identified disorder that is associated with dermatologic manifestations such as urticaria, flushing, pruritus, and atopic dermatitis (AD), as well as a broad range of other symptoms affecting multiple systems. Given the potential cutaneous manifestations and the fact that dermato-logic symptoms may be the initial presentation of HaT, awareness and recognition of this condition by dermatologists are essential for diagnosis and treatment. This review aims to summarize cutaneous presentations consistent with HaT and various conditions that share overlapping dermatologic symptoms with HaT...

Cutaneous T-cell lymphoma (CTCL) is a chronic form of skin cancer. Skin-directed therapies rarely achieve complete clearance of lesions, and recurrences are frequent. In this case series, 9 patients with stage IA to IVA2 CTCL received intralesional (IL) therapy with 5-fluorouracil (5-FU) and imiquimod (IMQ) cream 5% daily to recalcitrant plaques and tumors. All 9 patients attained a complete response (CR) with no recurrences reported and no severe side effects. We find that combination IL 5-FU and IMQ cream 5% daily is a well-tolerated, effective, and durable skin-directed therapy for recalcitrant plaques and tumors in CTCL...

Dietary supplements, including vitamins and their derivatives, have been utilized within the field of dermatology to treat a variety of skin conditions. Antioxidants inhibit oxidation and decrease cellular damage caused by free radicals, potentially preventing DNA damage due to UV radiation. Laboratory studies have demonstrated promising results supporting the possible role of antioxidants for prevention of skin cancer related to UV exposure. We review the effects of frequently encountered antioxidants and vitamins suggested for the chemoprevention of melanoma and nonmelanoma skin cancer (NMSC) in humans...

Cutaneous surgery often is performed in areas of extremely thin skin. Traditionally, wound closure in thin skin is complicated because the skin tears easily and wound breakdown can occur. Consequently, healing becomes a challenge. Our group of dermatologic surgeons has developed a novel effective technique that minimizes these problems, which we present step by step.
