Canalicular adenoma

Canalicular adenoma is most common in patients age 70 to 80, with females affected about four times as often as males. Most growths present in the upper lip; some also occur in the a few present in palate or buccal (cheek) tissue as a slowly enlarging mass. The growths will often arise in multiple places at the same time or develop multiple nodes, despite not being clinically invasive or malignant. ==Diagnosis==

Canalicular adenoma growths are usually small at the time they are noticed, with an average size of about 1.6 cm. Although it is a benign tumor, a positive diagnosis of canalicular adenoma may be necessary to exclude the existence of other medical conditions such as a basal cell adenoma, pleomorphic adenoma, adenoid cystic carcinoma, and polymorphous adenocarcinoma. ==Treatment==

Most instances of canalicular adenoma are treated with conservative surgery. ==References==
