Abstract

Chromoblastomycosis, a chronic cutaneous mycosis caused by pigmented fungi, is typically associated with trauma in the exposed parts of the body. We report a 68-year-old male farmer diagnosed with chromoblastomycosis clinically mimicking a cutaneous abscess on the back, an unusual location. Histopathological and mycological examination identified Fonsecaea pedrosoi. Treatment with itraconazole and cryotherapy showed improvement after 4 months. High suspicion index and biopsy are imperative for early diagnosis of chromoblastomycosis. This case adds to the limited cases reported in Korea, emphasizing the importance of considering chromoblastomycosis in diverse clinical presentations.
