Mucoepidermoid carcinoma, a malignant neoplasm of salivary gland, rarely arises within the jaws. Differential diagnosis should include an odontogenic cyst because the central mucoepidermoid carcinoma usually reveals either an unilocular or multilocular radiolucency with hyperostotic border. Long-term follow-up is needed due to late recurrence and clinical slow progress like other salivary gland tumors. We would like to report an unusual case of central mucoepidermoid carcinoma with a review of literature.
