[Subcutaneous phaeomycotic cyst of the ankle].
Phaeohyphomycosis is a rare mycotic opportunist disease witch usually affects immunodepressed patients. Infection follows a traumatic inoculation of fungi into the skin with formation of a subcutaneous cyst. We report the case of a 20-year-old woman presenting with a subcutaneous, painless, and recurrent cystic lesion on the right ankle for 9 years. A surgical excision was performed. Histopathologic examination showed a granuloma with central abscess surrounded by a thick fibrous tissue. After staining with PAS, septate hyphae and spores were found in the granuloma, consistent with a phaeomycotic cyst.
