Tumorous Type of Chromoblastomycosis: A Case Report

Background: Chromoblastomycosis (CMB) is a chronic cutaneous and subcutaneous mycosis caused by dematiaceous fungi, characterized by hyperproliferation of the tissues involved and by the presence of sclerotic bodies. Tumorous type of CMB maybe progress as result of late of seeking for treatment. If not recognized at an early stage, this disease might develop into complication and refractory to antifungal therapy. Case report: A case of 52-year-old male a farmer with history of erythematous lump with rough surface on the right foot that slowly felt pain and itchy that increasedsince15 years ago, working diagnosed as chromoblastomycosis. Dermatology state: There was tumor sized 3x4x4cm on the sole of right foot, accompanied with excoriation, superficial ulcer and reddish crusts on the top of tumor. Dermoscopic finding was the presence irregular black dots and yellowish orange ovoid structure. Direct light microscopy of skin scrapings samples using potassium hydroxide 20% showed multiple sclerotic bodies Histopathological examination showed pseudo-epitheliomatous hyperplasia, granulomatous reaction and sclerotic bodies. The examination was confirmed by culture of fungi found Fonsecaeapedrosoi. Discussion: Clinical appearance, potassium hydroxide 20%, histopathology examination and tissue culture supported the diagnosis of chromoblastomycosis. Uncomplianceoftreatmentmay lead several problems, such as difficulty in managing therapy because of the recrudescent character of the disease, potential association with the growth of epidermoid carcinoma in affected regions, and poor quality of life.
