Plain-English summary
An 8-year-old female spayed dog had a large, non-painful swelling in her left jaw area, which led her owner to seek veterinary help. A CT scan revealed an unusual mass near her salivary gland that was affecting nearby structures. During surgery, the vet removed the mass along with the affected salivary gland, and tests confirmed it was a rare type of tumor. Fortunately, the surgery was successful, and the dog was treated for recovery.

Abstract
A carcinoma ex pleomorphic adenoma was diagnosed in the left mandibular salivary gland of an 8-year-old female spayed dog. The animal presented with a large nonpainful swelling in the left submandibular region. A computed tomography scan detected an irregularly enhancing soft tissue mass that was closely associated with the left external ear canal and extended to the left wing of the atlas. On surgical exploration, the mass was intimately associated with the left mandibular salivary gland. Both the mass and the adjacent gland were removed, and the diagnosis was determined by histopathology. The tumor was comprised of basaloid and low columnar epithelial cells, many glandular units formed by well-differentiated sebocytes, and multifocal regions of necrosis, mineralization, and hemorrhage. Salivary gland tumors with sebaceous differentiation are very rare in animals, with one previously reported case in a cat.
