A case of cutaneous Exophiala spinifera infection.
A 66-year-old female had a solitary dark-red nodule measuring 1 cm in diameter on her left forearm. She often had trauma to her hands and arms. A histopathologic examination demonstrated granulomatous changes in the dermis. Under the high-power magnification yeast-like cells and short toruloid hyphal elements were observed in the granuloma. A few giant cells contained fungal elements. No sclerotic cells were found. On the basis of the histopathologic and mycologic findings, the lesion was diagnosed as a dematiaceous fungal infection caused by Exophiala spinifera. She was treated with oral itraconazole (200 mg/day) and topical heat therapy. The lesion was clinically improved within 58-days. However, E. spinifera was still isolated from the excisional specimen 92-days later. We believe that surgical excision is the choice of therapy if the lesion is small.
