Epidermodysplasia verruciformis: report of two patients with autosomal dominant inheritance.

Dermatol Online J 2021 Feb 15;27(2). Epub 2021 Feb 15.

Department of Dermatology, University of São Paulo Medical School, São Paulo/SP.

Epidermodysplasia verruciformis is a rare genodermatosis associated with mutations in the EVER1/TMC6 and EVER2/TMC8 genes. The inheritance is considered to be autosomal recessive, but reports suggesting an autosomal dominant inheritance indicate disease genetic heterogeneity. Its onset occurs in early childhood and presents as a combination of pityriasis versicolor-like, flat wart-like and seborrheic keratosis-like lesions, with a potential for malignant transformation, mainly squamous cell carcinoma.
