Plain-English summary
A cat was brought in because of a soft lump near the back of its jaw. After tests suggested it might be a serious tumor, the vet surgically removed the mass from the salivary gland. The lab results confirmed it was an oncocytoma, a type of tumor that can develop in salivary glands. This case is notable because it’s the first time an oncocytoma has been reported in a cat's salivary gland, and the cat did well after the surgery, surviving long-term.

Abstract
A cat was referred for investigation of a soft tissue mass caudal to the left mandible. Initial investigations suggested a malignant salivary gland tumour, and the mass was removed by extracapsular resection of the mandibular gland. Histopathology showed an oncocytoma within the salivary gland. An oncocytoma is a neoplastic transformation of oncocytes. Oncocytes are cells with a small nucleus and intense eosinophilic granular cytoplasm due to numerous mitochondria, which proliferate during ageing in exocrine and endocrine glandular tissues. Physiological proliferation occurs next to oncocytosis, oncocytoma, and oncocytic carcinoma. This is the first report of an oncocytoma in a feline mandibular salivary gland, and the first report of long-term survival after surgical removal.
