Cutaneous phaeohyphomycosis caused by Pyrenochaeta unguis-hominis in a diabetic patient: A case report

Phaeohyphomycosis, caused by opportunistic rare fungi, has increasingly been reported in diabetic and immunosuppressed patients. Pyrenochaeta unguis-hominis (P. unguis-hominis), a member of the dematiaceae group, has been identified to cause human nail infection. We report a rare case of cutaneous phaeohyphomycosis in a diabetic female caused by P. unguis-hominis.
