A Rare Presentation of Canalicular Adenoma of the Parotid Gland

A Rare Presentation of Canalicular Adenoma of the Parotid Gland

Canalicular adenoma is an uncommon benign neoplasm of the salivary glands. It occurs almost exclusively in the upper lips, next common site being the buccal mucosa. Parotid gland is a rare site for its occurrence. It is most likely to occur in the elderly.
Although canalicular adenoma is a rare entity, especially when it is not located on the upper lip, it is important to consider this tumor type when differentiating between pleomorphic adenoma, basal cell adenoma, Warthin’s tumor, and especially adenoid cystic carcinoma, when this occurs in the parotid gland. Histopathological biopsy is required for accurate diagnosis, because it may be difficult to differentiate canalicular adenomas from other diseases using FNACs alone.
Here we report a case of a 43-year-old male, who presented with a history of a swelling below the right ear. The patient was subjected to a fine needle aspiration cytology (FNAC) and the diagnosis of pleomorphic adenoma was made. The lesion was subsequently excised and sent for histopathology.
