Lipomatous infiltration of the canine salivary gland.

Benign connective tumours of the canine salivary glands are rare. This report describes lipomatous infiltration of parotid or submandibular salivary glands in seven dogs in which the glands were enlarged as a result of infiltration by fat cells; they appeared to have been successfully treated by local excision. The precise cause of the lipomatous infiltration in the dogs is unclear but different causes of similar lesions in humans are discussed.
