Canalicular adenoma is a benign neoplasm of the minor salivary glands. The most common site is the upper lip, and the adenoma usually appears as a single lesion. Few cases of multiple foci of canalicular adenoma (CA) have been reported in literature. We report a case of a 78-year-old woman with CA of the nasolabial wrinkle on both sides of the nose, which occurred at the same time. The lesions recurred after about 1 year. This report adds to the literature another case of multiple, bilateral CA with synchronous occurrence.
