Kuttner tumor: a report of an underdiagnosed entity.

Kuttner tumor (KT) is a benign tumor-like lesion predominantly involving the submandibular gland of middle aged individuals. Although described more than a century ago, this clinical entity which masquerades as carcinoma is underdiagnosed by many surgeons. KT is usually diagnosed by histopathologist when the lesion is surgically biopsied to confirm clinical diagnosis of malignancy.
