Küttner’s tumour of the submandibular gland

Küttner’s tumour of the submandibular gland. Küttner’s tumour (chronic sclerosing sialadenitis) is a chronic inflammatory disease of the salivary glands that produces a firm and relatively painful swelling of the glands. Although Küttner’s tumour is a common submandibular disease, many clinicians and pathologists have under-recognized this entity because of its superficial resemblance to neoplasia and the presence of only a few reports in the English literature. We report a case of Küttner’s tumour in a 41-year-old male who presented with a painless submandibular mass, and discuss its histological and clinical characteristics.
