Chromoblastomycosis Caused by Fonsecaea monophora Mimicking Lichen Planus

Yasmine Oprea et al. Cureus. .

Abstract

Chromoblastomycosis is a rare fungal infection acquired by traumatic inoculation of pigmented fungi from an environmental source. The polymorphic presentation of chromoblastomycosis may mimic other dermatologic conditions, leading to delays in diagnosis. Thus, histopathology is critical in identifying the presence of fungi and confirming the diagnosis. We present a case of chromoblastomycosis caused by the organism Fonsecaea monophora mimicking a lesion of lichen planus to highlight the importance of histopathology in the diagnosis of this condition.

Keywords: chromoblastomycosis; dematiaceous fungi; fonsecaea monophora; fungal infection; lichen planus.
