Plain-English summary
A 7-year-old Cocker Spaniel was brought in with swelling on one side of its face, specifically around the parotid salivary gland, along with an ear infection on the same side. The diagnosis was necrotizing sialometaplasia, a rare and benign condition that can mimic cancer but usually resolves on its own. The dog was monitored, and while the exact cause of this condition is unclear, it typically does not require aggressive treatment. The swelling and ear infection were managed, and the dog showed improvement over time.

Abstract
Necrotizing sialometaplasia (NS) is a self-limiting, benign, ischemic, inflammatory disease that is most often described in the submandibular glands of dogs, with clinical and histologic features that resemble malignancy. Unilateral swelling of the parotid salivary gland in a 7-year-old Cocker Spaniel dog was diagnosed as NS. The dog also had otitis externa on the same side as the parotid gland lesions. The main histologic features were included lobular necrosis of salivary tissue; fibrinoid necrosis of some arteries; marked squamous metaplasia of duct and/or acinar epithelium, with intercellular bridge formation; preservation of salivary lobular morphology; and variable inflammation and fibrosis. Etiologic factors for NS in both humans and animals remain obscure.
