RESUMO
A 13-year-old, domestic shorthair cat was presented for evaluation of a right tarsal mass. Physical examination revealed a 5 cm × 5 cm × 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.

A 14-year-old spayed female domestic shorthair cat presented with an interscapular mass. A computed tomography scan, biopsy, and histological examination revealed a fibrosarcoma adjacent to a pet identification microchip. Because the cat was previously vaccinated at this site, it is not possible to establish definitive causation of the fibrosarcoma, but this is the first report of a tumor in the vicinity of a microchip in a cat. Microchip-associated tumors have been reported in rodents and dogs. Veterinarians should be aware that because inflammation may predispose felines to tumor formation, separation and observation of vaccination and implantation sites are indicated. Adherence to American Association of Feline Practitioners (AAFP) vaccination guidelines and monitoring of microchip implantation sites are recommended.
