Cutaneous chromoblastomycosis mimicking melanoma in a renal transplant recipient

Abstract

Chromoblastomycosis is a primary implantation mycosis caused by melanized fungi. It affects mainly populations from remote and rural areas, and may cause significant morbidity and mortality. A 69-year-old kidney transplant recipient woman presented with a dark nodule on the first left toe and a satellite lesion. Dermoscopic exam showed multiple clustered black dots, blackened homogenous area and chrysalides, which led to the diagnostic hypothesis of melanoma. Histopathological examination was compatible with chromoblastomycosis.
