Phaeohyphomycotic cyst in the Foot by Exophiala.

A 52-year-old male, presented to us with a swelling over plantar aspect of right foot following trauma. Clinically it was a cystic swelling diagnosed as an abscess; ultrasound showed thick walled multilocular collection with thick echogenic debris, following which complete excision of the swelling was done. A part of the swelling was sent for histopathological examination and cut section showed thick purulent material. Other part sent for culture sensitivity grew, Exophiala, which belongs to Dematiaceous group of fungi. Surgical excision with antifungal treatment is the management in general for fungal cyst, whereas in our case complete excision was done without antifungal treatment.
