Abstract

Progressive symmetrical erythrokeratoderma (PSEK) is a rare disorder of cornification characterized by epidermal hyperproliferation with predominantly autosomal dominant inheritance, and sometimes autosomal recessive transmission has been also observed. The molecular basis of PSEK in the vast majority of patients has not yet been established. Patients with PSEK usually respond to oral retinoid therapy. In this report, we describe the patient with PSEK. A 20-year old female with multiple hyperpigmented patches on neck, back and lower legs since birth. Histopathological finding is compatible with progressive symmetrical erythrokeratoderma.
