Cystic chromomycosis due to Wangiella dermatitidis

Abstract

Chromomycosis is a chronic, slowly progressive disease of the skin and subcutaneous tissue produced by several species of dematiaceous or pigmented fungi, especially Phialophora gougeroti. Verrucous nodules and flattened annular plaques are the most frequently reported skin lesions in chromomycosis. Deep abscesses and cystic lesions were reported. A [human] case of cystic chromomycosis due to W. dermatitidis, which developed following a non-penetrating injury to the thumb, is described.
