A rare case report of intraosseous adenoid cystic carcinoma of the mandible

Adenoid cystic carcinoma (ACC) is an uncommon malignant tumor of the salivary glands. It generally involves the minor salivary glands, and the hard palate is the most common site. ACC presents as a slow growing mass with mild pain and usually demonstrates perinueral invasion. An intraosseous occurrence of ACC is a very rare and when it occurs the mandible is more commonly involved than the maxilla. A Pubmed search has revealed only 26 case reports of intraosseous ACC involving the mandible until date. Hence, reporting one such rare case of intraosseous ACC in a 49-year-old male patient involving the mandible.
