Zosteriform cutaneous leishmaniasis diagnosed with the help of dermoscopy.

Cutaneous leishmaniasis is usually easy to recognize; however, several atypical features exist, which may pose a diagnostic challenge. Here we report a 55-year-old female patient, who presented with an itchy and painful eruption localized in a dermatomal distribution along the right upper chest. Although the clinical appearance of the lesions suggested the diagnosis of herpes zoster, dermoscopic evaluation revealed erythema, hyperkeratosis, burst star whitish appearance and hairpin vessels, compatible with the diagnosis of cutaneous leishmaniasis.

Atypical "allergic crease".

Background: The allergic crease (nasal crease) is a transverse line, common among patients who suffer from allergic rhinitis. Although it is a very prevalent condition, the skin manifestations which accompany this condition have been only sparsely reported.

Main Observation: We describe an 18-year-old man with allergic rhinitis, who developed cornified papules along an allergic crease.

Mutations in lipase H cause autosomal recessive hypotrichosis simplex with woolly hair.

Background: Mutations in lipase H (LIPH) are a rare cause of autosomal recessive hypotrichosis (HT) simplex.

Objective: In this study, we investigated the clinical and molecular basis of HT simplex with woolly hair in 3 nonrelated families.

Methods: Three families of Jewish, Arab Muslim, and Italian origin that presented with HT with woolly hair were studied.

Genomewide scan for linkage reveals evidence of several susceptibility loci for alopecia areata.

Alopecia areata (AA) is a genetically determined, immune-mediated disorder of the hair follicle that affects 1%-2% of the U.S. population.
