Plain-English summary
A 14-year-old spayed female domestic shorthair cat was found to have a mass between her shoulder blades during a vet visit. Tests, including a CT scan and biopsy, showed that the mass was a fibrosarcoma, a type of tumor, located near her microchip implant site. While it's unclear if the microchip caused the tumor, this case is the first of its kind reported in cats. Vets recommend monitoring the area where microchips are implanted and following vaccination guidelines to help prevent potential issues. The cat's treatment plan would depend on the tumor's specifics and her overall health.

Abstract
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.
