Küttner's tumour: a case report.

Küttner's tumour (chronic sclerosing sialadenitis) is a chronic inflammatory disease of the salivary glands. It is a totally benign lesion. However, because of its clinical features, the clinical diagnosis is often that of a salivary gland neoplasm. We present a case of unilateral Küttner's tumour in the left submandibular salivary gland and discuss clinical, imaging and histological features.
