Primary intraosseous mucoepidermoid carcinoma of maxilla

Primary intraosseous mucoepidermoid carcinoma (PIOC) of the jaw bones is an extremely rare malignant salivary gland tumor, comprising 2-3% of all mucoepidermoid carcinomas reported. It is commonly seen in the posterior part of the mandible; its occurrence in the maxilla is rare. They have been reported in patients of all ages, ranging from 1 to 78 years, with the overwhelming majority occurring in the 4th and 5th decades of life. They are histologically low-grade cancers and radiographically seen as uniocular or multiocular lesions. We report a rare case of PIOC in posterior palatal region in 18-year-old male.
