Central mucoepidermoid carcinoma radiographically mimicking an odontogenic tumor: A case report and literature review

Central mucoepidermoid carcinoma (CMC) of the jaw bones is a rare malignant salivary gland tumor of unknown pathogenesis, comprising about 4% of all mucoepidermoid carcinomas (MECs). Most cases are histologically classified as a low-grade tumor and radiographically appear as a well-defined unilocula...

Description
Summary:Central mucoepidermoid carcinoma (CMC) of the jaw bones is a rare malignant salivary gland tumor of unknown pathogenesis, comprising about 4% of all mucoepidermoid carcinomas (MECs). Most cases are histologically classified as a low-grade tumor and radiographically appear as a well-defined unilocular or multilocular radiolucent lesion. Block resection or wide local excisions are the treatment of choice and patients usually show a good overall prognosis although a long-term follow-up is necessary. This report describes a case of a 28-year-old male with MEC in the posterior region of the mandible and discusses its clinical, radiographic and histopathological findings. Although rare, CMC may be considered a differential diagnosis in cases of proliferative and osteolytic lesions in the oral cavity even when its clinical and/or radiographic findings do not suggest malignancy.
