Dermoscopy of chromoblastomycosis

Abstract

Chromoblastomycosis is a chronic cutaneous fungal infection commonly caused by Fonsacea and Cladophialophora spp. Dermoscopy is a non-invasive, real-time diagnostic tool for rapid bedside diagnosis of various inflammatory and non-inflammatory disorders and can be an excellent modality for evaluation of cutaneous mycosis, for which it shows characteristic brown dots, crust, scales and yellow orange structures.

Keywords: chromoblastomycosis; dermoscopy.
