Bathing suit ichthyosis: Two Burmese siblings and a review of the literature.

Bathing suit ichthyosis (BSI) is a subtype of autosomal recessive congenital ichthyosis (ARCI) characterized by the development of large platelike scales mainly limited to the trunk. It is caused by temperature sensitive variants in transglutaminase 1, encoded by the gene TGM1. We describe a rare case of intrafamilial variation in phenotypic expressivity in two Burmese siblings with BSI that demonstrates the heterogeneity of the disorder within the same family and even in the same individual across time. We also present a concise review of the genotypic spectrum of BSI from 54 cases reported in the literature as evidence that both environmental and additional genetic factors can significantly alter the clinical phenotype.

Atopic dermatitis made easy: The Schachner Ladder.

The vast majority of atopic dermatitis follows a mild, chronic relapsing course. In this article, we highlight the art and practice of treating atopic dermatitis based upon a foundation of maintenance care and a ladder of therapy that can teach patients and their families how to best tailor their pharmaceutical options to optimize the management of their disease.

Drug reaction with eosinophilia and systemic symptoms: Pediatric case series and literature review.

BACKGROUND: Pediatric Drug reaction with eosinophilia and systemic symptoms (DRESS) is an uncommon disease that can be difficult to diagnose. This case series and literature review highlights the clinical features of pediatric DRESS and underscores the differential diagnoses, culprit medications, and need for clinical follow-up to detect associated autoimmune sequelae. OBJECTIVE: To describe the clinical and laboratory features of pediatric DRESS, identify associated culprit medications, and discuss the natural history of disease. METHODS: Ten cases of pediatric DRESS were identified in the electronic medical record by searching the inpatient dermatology consultation list at Indiana University between 2013 and 2018. Clinical and laboratory data were collected including demographics, differential diagnoses, culprit medications, resolution of disease, and autoimmune sequelae. RESULTS: Pediatric patients with DRESS presented at a mean age of 11.5 years and demonstrated a mean time from drug initiation to onset of symptoms of 4 weeks. The most common inciting drugs included antibiotics (62.5%) followed by antiepileptics (37.5%). Rash and transaminitis resolved by 3 weeks, and 20% of patients, all female, developed autoimmune sequelae including Hashimoto's thyroiditis and an undifferentiated connective tissue disorder and occurred at an average of 14.5 weeks after diagnosis. LIMITATIONS: This was a small retrospective study of an uncommon clinical diagnosis at a single institution. CONCLUSIONS: Pediatric DRESS was most commonly caused by antibiotics which are being increasingly recognized in the literature as the predominant culprit medications. The development of autoimmune sequelae is a notable consequence that can present weeks after illness and may preferentially affect female patients.

Short anagen syndrome: Case series and literature review.

BACKGROUND/OBJECTIVES: Short anagen syndrome is a hair cycle disorder usually diagnosed in early childhood and characterized by short hair length due to short duration of the anagen phase. The objective was to review the presentation and demographic characteristics of short anagen syndrome and compare them with the most common differential diagnosis, loose anagen syndrome. METHODS: A retrospective review of eight children with short anagen syndrome was performed at the University of Miami Outpatient Dermatology Clinic. RESULTS: The diagnosis of short anagen syndrome was confirmed according to clinical findings and characteristic short telogen hairs with pointed tips on the hair pull test. CONCLUSION: This is the largest reported clinical series of short anagen syndrome thus far in the literature.

Ichthyosiform Pityriasis Rubra Pilaris-Like Eruption Secondary to Ponatinib Therapy: Case Report and Literature Review.

Tyrosine kinase inhibitors have revolutionized the chemotherapy arena as targeted therapies for a multitude of malignancies. They are more selective than conventional chemotherapy, and often elicit fewer systemic adverse events, however toxicities still exist. Cutaneous toxicities are common and their management presents a novel challenge to physicians and patients. Ponatinib is a third-generation tyrosine kinase inhibitor increasingly reported to cause cutaneous eruption. A 50-year-old woman with a history of chronic myelogenous leukemia presented with a 4-month history of worsening atrophic and ichthyosiform pink plaques involving the axillae, thighs and abdomen; red patches were also observed on the cheeks and forehead. She was started on the third-generation, ponatinib, 5 months earlier because of disease refractory to previous therapies including interferon, imatinib, dasatinib and bosutinib. A skin biopsy revealed perifollicular fibrosis, alternating orthokeratosis and parakeratosis, and a sparse perivascular lymphocytic infiltrate consistent with a pityriasis rubra pilaris-like reaction. Topical tretinoin 0.025% cream was initiated, resulting in resolution within 3 weeks without discontinuation of ponatinib. A review of previous reports identified significant similarities among the ponatinib-induced drug reactions. Here, we highlight not only that cutaneous eruptions occur on ponatinib therapy, but that the dermatologic manifestations are characteristic and unique, and benefit from retinoid therapy, without requiring interruption of vital chemotherapy.
