A Case of Phaeohyphomycosis Caused by Exophiala oligosperma in a Renal Transplant Patient Successfully Treated with Posaconazole

Phaeohyphomycosis is an uncommon mycotic infection caused by dematiaceous fungi. We report a 53-year-old male who presented with phaeohyphomycosis on his upper extremities, 6 months after renal transplantation. Biopsy revealed pigmented moniliform hyphae and cultures grew Exophiala oligosperma. The lesions completely resolved after 3 months of treatment with posaconazole.
