Abstract:
We report a case of subcutaneous phaeohyphomycosis of foot, which is a mycotic disease that produces brown pigmented hyphae, pseudohyphae and yeast form in combination. The patient was immunocompetent and had injury 23 years before, and developed a non healing foot ulcer which was clinically suspected as tuberculous or carcinomatous etiology. Local wide excision was done and sent in formalin for histopathological examination. Microscopically pigmented septate, hyphae and yeast forms were identified on hematoxylin and eosin stained sections which were confirmed by special stains such as periodic acid-Schiff and Gomori's methenamine silver stains.
