Erythema dyschromicum perstans in early childhood

Erythema dyschromicum perstans (EDP) is a rare disorder characterized by asymptomatic, slowly progressive, ash-gray macular pigmentation of the skin which usually occurs from age 5 through adult life. We have experienced two cases of EDP in children aged 2 and 3, both exceptionally younger than the previously reported cases. We therefore suggest that EDP should be included in the differential diagnosis of pigmentary disorders occurring at an early age.
