Abstract
Opportunistic subcutaneous fungal infections are increasing nowadays due to the growing number of medical conditions causing immunosuppression, especially organ transplant. The incidence rate of subcutaneous phaeohyphomycosis is very low. Most studies found are case reports. They showed a wide variation of clinical presentations. Pyrenochaeta romeroi, a fungus from the Dematiaceae group is a saprophyte found in soil and plants and a possible causative agent of phaeohyphomycosis. We present a rare case of subcutaneous phaeohyphomycosis caused by P. romeroi mimicking a synovial cyst in a diabetic patient.
Highlights
Phaeohyphomycosis is a heterogeneous group of infections due to dematiaceous fungi with several clinical presentations, from superficial to deep infections (Borelli, 1979; Rinaldi, 1996)
Pyrenochaeta romeroi has been recently described as a causative agent of phaeohyphomycotic cyst in few cases while it was already known as an agent of mycetoma (Thammayya et al, 1979; Girard et al, 2004; Badali et al, 2010a; Khan et al, 2011)

Summary
Phaeohyphomycosis is a heterogeneous group of infections due to dematiaceous fungi with several clinical presentations, from superficial to deep infections (Borelli, 1979; Rinaldi, 1996). Pyrenochaeta romeroi has been recently described as a causative agent of phaeohyphomycotic cyst in few cases while it was already known as an agent of mycetoma (Thammayya et al, 1979; Girard et al, 2004; Badali et al, 2010a; Khan et al, 2011). This saprophytic fungus is widely distributed in the environment and found in soil, wood and plants in tropical area. Our patient showed signs of improvement after surgical treatment without any antifungal treatment
