Abstract
Canalicular adenoma is an uncommon benign salivary gland neoplasm that generally affects minor salivary glands. This lesion is more common in older women, located on the upper lip. It presents clinically as an asymptomatic swelling, blue colored, resembling a mucocele. A black female patient, 49 years old, attended the Oral Medicine clinic complaining of a mass located on the upper lip, with evolution of 3 years. Extraoral examination showed no abnormalities. Intraoral examination showed a nodular lesion at the midline of the upper lip, well defined, firm, about 3 cm in diameter. The diagnostic hypotheses were pleomorphic adenoma and lipoma. An excisional biopsy was performed and microscopic examination showed canalicular adenoma. After 5 months of follow-up no signs of recurrence were observed.
