(92-94) Rotellini et al (95) examined 101 benign and malignant salivary gland tumors, including 36 pleomorphic adenomas, 8 myoepitheliomas, 3 basal cell adenomas, and 1 canalicular adenoma among the benign tumors; 16 mucoepidermoid carcinomas, 10 adenoid cystic carcinomas, 8 acinic cell carcinomas, 8 polymorphous low-grade adenocarcinomas, 7 salivary duct carcinomas, and 4 epithelial-myoepithelial carcinomas among malignant tumors.
(65-69) Curran et al (70) reported that 96% of canalicular adenomas demonstrated weak to strong cytoplasmic staining for GFAP, which was confined to a row of cells at the tumor/connective interface.
INTRODUCTION: Canalicular adenoma is an uncommon benign salivary gland tumor almost exclusively occurring in intra-oral glands.
FEATURES ARE CONSISTENT WITH CANALICULAR ADENOMA OF SALIVARY GLAND
Only two other intra-mandibular canalicular adenoma cases have been reported up till now.
Canalicular adenoma of the palate: case report and literature review.
Canalicular adenomas are benign neoplasms with a unique predilection for the upper lip (~80% of cases).
Canalicular adenomas are typically smaller than 2 cm.
Based on this month's Pathology Clinic, by Penner and Thompson, approximately what percentage of cases of canalicular adenomas
occur in the upper lip?
