Abstract

Canalicular adenoma (CAD) is an uncommon benign tumor of minor salivary glands with predilection for the upper labial mucosa. An 80-year-old female presented with nine submucosal nodules of the upper labial mucosa and bilateral buccal mucosa. Histopathologic examination revealed multifocal circumscribed tumor islands with a tubular growth pattern within a loose hypocellular myxoid background stroma. Interconnecting rows of columnar tumor cells imparted a canalicular morphology. In addition to the characteristic histopathologic findings, a comprehensive immunohistochemical panel supported a final diagnosis of multifocal CAD. Synchronous multifocality in CAD is an infrequent finding and this sine qua non clinicopathologic correlation article exemplifies such a case.
