Canalicular adenoma of the palate: case report and literature review.

Canalicular adenoma is a rare benign salivary gland tumor of the oral cavity, typically located in the upper lip and buccal mucosa and infrequently found on the palate. The tumor is usually confined to soft tissue and rarely presents with bone erosion. A case of a large and locally-aggressive palatal canalicular adenoma is presented. The lesion presented herein was an asymptomatic ulcerated mass with significant bone erosion. The tumor was managed surgically with excision and reconstruction of the resulting palatal defect with a full temporalis muscle flap.
