Abstract
The first report of a case of feline phaeohyphomycosis due to Fonsecaea pedrosoi is presented. Fonsecaea pedrosoi is an aetiologic agent of both human phaeohyphomycosis and chromoblastomycosis. In our cat, the lesion was confined to the skin and appeared as a firm swelling on the bridge of the nose. Diagnosis was based on histological examination of a cutaneous biopsy and fungal culture of a tissue sample on Sabouraud’s dextrose agar. Further diagnostic tests failed to reveal an underlying immunosuppression. Two treatment cycles with itraconazole, at the oral dose of 5 mg kg−1 given twice daily, induced complete clinical remission, but relapses occurred.
