Chromoblastomycosis - A clinical mimic of squamous carcinoma.

Chromoblastomycosis is a chronic fungal infection of the skin and subcutaneous tissue caused by dematiaceous fungi. We report a case of chromoblastomycosis caused by Fonsecaea pedrosoi from a subtropical region of India that developed over the left foot of a 45-year-old male farmer and was provisionally diagnosed as squamous cell carcinoma. The patient presented with irregular warty growths over the left foot, which had started one year previously, and has gradually progressed over a year to involve the lateral aspect of left leg. The diagnosis of chromoblastomycosis was confirmed by histopathology and fungal culture.
