Invasive hyalohyphomycosis caused by Scopulariopsis brevicaulis in a patient undergoing allogeneic bone marrow transplant.

Scopulariopsis brevicaulis is a common soil saprobic mould. Occasionally, S. brevicaulis has been reported as an etiologic agent of human disease. The spectrum of human mycoses includes toenail infection, hypersensitivity pneumonitis, fungus ball formation in a preformed pulmonary cavity, and, most recently, documented deep tissue infections in immunocompromised hosts. A case of invasive hyalohyphomycosis of the great toe caused by S. brevicaulis is reported in an allogeneic bone-marrow transplant recipient.
