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, but deep abscesses and cystic lesions have also been reported. We describe herein a case of cystic chromomycosis due to Wangiella dermatitidis that developed following a nonpenetrating injury to the thumb.
