Chronic sclerosing sialadenitis of the submandibular and parotid glands: a report of a case and review of the literature.

Chronic sclerosing sialadenitis (also known as Küttner tumor) is a chronic inflammatory condition of the salivary glands, first described by Küttner in 1896. Clinically, the disease cannot be distinguished from a true neoplasm. The submandibular gland is affected more commonly than any other salivary gland. This report is of a case of widespread swelling of the salivary glands in which histologic features of chronic sclerosing sialadenitis were seen in the submandibular and parotid glands. The etiology, pathogenesis, and differential diagnosis of this disease and the clinical outcome of this case are discussed and presented.
