A case of canalicular adenoma of the maxillary gingivolabial fold in a Japanese 47-year-old woman is reported. The tumor was approximately 10 mm in diameter, elastic soft, freely movable, and painless. It was excised under local anesthesia.
Histologically, the tumor was entirely encapsulated. Small ducts were formed, chiefly by bilayered, columnar epithelial tumor cells. The stroma was loose and relatively highly vascular. Canalicular adenoma was the histopathological diagnosis according to the revised WHO classification (1991).
The postoperative course was satisfactory. The clinicopathological findings of this tumor were discussed briefly, referring to the literature.
