May also cause onychomycosis as well as dark grain mycetoma and phaeohyphomycosis at various sites, including subcutaneous tissue and deep tissues. Keratitis, sinusitis, cutaneous and subcutaneous infections, peritonitis, onychomycosis, endocarditis, endophthalmitis, and pneumonia as well as disseminated disease have also been reported.
