Cutaneous phaeohyphomycosis in renal allograft recipients: report of 2 cases and review of the literature.

Dematiaceous molds are increasingly recognized as important human pathogens. We report 2 cases of cutaneous phaeohyphomycosis in renal allograft recipients, caused by Alternaria alternata and Curvularia spp., respectively, which demonstrate the diversity in clinical presentation, the different therapeutic strategies, and the clinical importance of azole antifungal-induced drug-drug interactions with immunosuppressive therapy.
