Epidermodysplasia verruciformis (EV) is a rare genodermatosis characterized by abnormal susceptibility to cutaneous human beta-papillomavirus infections causing persistent flat warts or pityriasis versicolor-like lesions. This generalized verrucous skin disorder resembles generalized verrucosis, but these 2 conditions are distinguished by differences in clinical manifestation and the human papillomavirus types involved. A breakthrough in our understanding of EV was the discovery that homozygous inactivating mutations in TMC6 (EVER1) and TMC8 (EVER2) determine susceptibility to this disorder; however, they have not solved all EV cases fully...

BACKGROUND: The histopathologic differences among palmar psoriasis (PP), hand eczema (HE), and hyperkeratotic hand dermatitis (HHD) have been poorly described. OBJECTIVES: We sought to distinguish among PP, HE, and HHD on a histopathologic basis. METHODS: We retrospectively analyzed the histology of hematoxylin-eosin-stained sections obtained from 96 patients diagnosed with PP, HE, or HHD. RESULTS: The patients were divided into 4 subgroups: PP (n = 16, group A), HE without atopic or nummular dermatitis (n = 41, group B), HE with atopic or nummular dermatitis (n = 14, group C), and HHD (n = 25, group D)...

BACKGROUND: Neurofibromatosis type 1 (NF-1) predisposes individuals to the development of benign and malignant tumors. The association of NF-1, juvenile xanthogranuloma (JXG), and juvenile myelomonocytic leukemia has been described in the literature. It is unclear whether JXG alone constitute a risk factor for leukemia or other malignancies in children with NF-1. OBJECTIVE: To determine if there is an association between NF-1, JXG, and malignancy. METHODS: We conducted a retrospective case-control study comparing children with NF-1 and malignancy (cases) with sex- and age-matched children with NF-1 without malignancy (controls)...

REVIEW
William Damsky, Brett A King
New molecularly targeted therapeutics are changing dermatologic therapy. Janus kinase-signal transducer and activator of transcription (JAK-STAT) is an intracellular signaling pathway upon which many different proinflammatory signaling pathways converge. Numerous inflammatory dermatoses are driven by soluble inflammatory mediators, which rely on JAK-STAT signaling, and inhibition of this pathway using JAK inhibitors might be a useful therapeutic strategy for these diseases. Growing evidence suggests that JAK inhibitors are efficacious in atopic dermatitis, alopecia areata, psoriasis, and vitiligo...

BACKGROUND: Acetylcholine receptor (AchR) antibody levels significantly correlate with disease severity at initial pemphigus diagnosis and during follow-up. However, it is not clear if they are just an epiphenomenon or a potential trigger of the known pathogenic process in pemphigus vulgaris. OBJECTIVE: We sought to assess the changes in anti-muscarinic (M3) AchR and anti-desmoglein (Dsg) antibody titers with therapy. METHODS: This was a hospital-based cohort study involving 45 patients with active pemphigus...
