Case report. A case of chromoblastomycosis effectively treated with terbinafine. Characteristics of chromoblastomycosis in the Kitasato region, Japan.

A 38-year-old male with history of trauma in the left gluteal region 20 years ago presented with a dark red skin eruption at the traumatized area. It gradually grew to form an erythematous plaque with a well-defined border. Clinical findings and mycological cultures resulted in the diagnosis of chromoblastomycosis due to Fonsecaea pedrosoi. After initial administration of 5-fluorocytosine and local heat an almost complete cure was achieved with terbinafine combined with local heat therapy. A review is given on the chromoblastomycosis cases observed in the Kitasato region in Japan.
