Intraosseous mucoepidermoid carcinoma: report of two cases.

Intraosseous mucoepidermoid carcinoma is a rare tumor which affects women more than men and is more common in the mandible. The radiological examination reveals a well-defined unilocular or multilocular radiolucent lesion. This tumor may resemble a glandular odontogenic cyst, particularly in incisional biopsies. The accurate diagnosis of these lesions is imperative because the subsequent treatment of each lesion would be different. The purpose of this study is to report two cases of intraosseous mucoepidermoid carcinoma and explicate the differentiating criteria of this lesion from the glandular odontogenic cyst.
