An association of Alternaria alternata and Scopulariopsis brevicaulis in cutaneous phaeohyphomycosis.

Rare molds are increasingly emerging as a cause of deep and invasive fungal infections. We report here a rare case of cutaneous phaeohyphomycosis of the lower limbs due to Alternaria alternata associated with extra-ungual localization of Scopulariopsis brevicaulis. Diagnosis was made based on repeated, direct, microscopic mycological and histological examinations. The study revealed hyphae and fungal cells in a granulomatous dermal infiltrate. Identification of the molds was based on macroscopic appearance on culture of samples from the lesions on Sabouraud's dextrose agar and microscopic appearance on Lactophenol cotton blue following slide culture.
