Canalicular adenoma of the hard palate: A rare case report

Canalicular adenoma (CA) is a rare, benign salivary gland tumor that has special tendency to occur in the upper lip. Buccal mucosa is the second most common site. It occurs more often in older patients with peak prevalence in the seventh decade of life. A definitive female predominance has been reported. According to the latest English published literature, 531 cases of CA have been reported. We present a case of CA of the hard palate that presented in a 29‑year‑old female patient. The histopathological and immunohistochemical findings showed typical features of CA and intense expression of pan‑cytokeratin and S‑100 protein. We also review its differential diagnosis from other salivary gland tumors.
