Abstract

Chronic sclerosing sialadenitis also known as ‘Küttner’s tumour’ (KT) is a benign chronic inflammatory condition first described by Küttner, clinically presenting as a firm swelling, often simulating a neoplasm. The condition is usually misrecognised and the correct diagnosis is made after the excision of the gland. Recent evidence suggests that Küttner’s tumor may be characterized by IgG4-related inflammation. An accurate preoperative diagnosis can be made by awareness of the condition, imaging and histopathopathology features, thereby potentially avoiding excision of an otherwise benign condition. Küttner’s tumour most commonly affects submandibular gland. Küttner’s tumour of the parotid and minor salivary glands are extremely rare. We report a case of a 69 year old man with this interesting and uncommon entity affecting the parotid gland.
