Subcutaneous infection of a cat by Colletotrichum species

A 13-year-old, domestic shorthair cat was presented for evaluation of a right tarsal mass. Physical examination revealed a 5 cm x 5 cm x 5 cm, soft, fluctuant, subcutaneous tarsal mass. Thoracic radiographs revealed several discrete lung parenchymal lesions. Abdominal ultrasound revealed abnormal architecture to both kidneys. Fungal culture and sensitivity from the subcutaneous mass revealed a uniform growth of Colletotrichum species that was susceptible to itraconazole. Colletotrichum species infection was confirmed in the subcutis and suspected to be disseminated. Colletotrichum species fungal infections in cats have not been previously documented.
