Abstract
BACKGROUND: Numerous etiologic agents of subcutaneous phaeohyphomycosis have been reported. Colletotrichum spp, common plant pathogens, have been reported as a cause of ocular keratomycosis, but only one previous case of cutaneous disease (hyalohyphomycosis) has been attributed to this genus. OBJECTIVE: Our purpose was to describe 3 cases of subcutaneous phaeohyphomycosis due to Colletotrichum spp occurring in patients undergoing chemotherapy for hematologic malignancies. METHODS: Three cases of Colletotrichum-induced phaeohyphomycosis are reviewed. The clinical and histologic features of this infection are presented, the antifungal susceptibilities are reported, and treatment options are discussed. RESULTS: We describe the first report in which C coccodes and C gloeosporioides are implicated as etiologic agents of subcutaneous phaeohyphomycosis. Despite treatment, one patient died after the onset of visceral fungal disease. CONCLUSION: Colletotrichum spp may cause life-threatening phaeohyphomycosis in immunosuppressed patients. Prompt recognition and intervention with surgical and antifungal treatment may result in decreased morbidity and mortality associated with these infections.
