Central Mucoepidermoid Carcinoma with Non-Hodgkin Lymphoma: A Case Report

Introduction: central mucoepidermoid carcinoma (cmec) is a rare primary intraosseous bony lesion. the mandible is more commonly affected than the maxilla. cmec is frequently misdiagnosed radiographically and clinically as a benign odontogenic tumor or cyst. case presentation: we present a rare case with a secondary malignant neoplasm. a male patient was initially diagnosed with b-cell non-hodgkin lymphoma. three months after his initial diagnosis, he presented with a large painless mass in the anterior region of his mandible. histopathological examination revealed low‐grade cmec. conclusion: we reported a very rare case of cmec in a patient treated for non-hodgkin lymphoma without radiotherapy. previous cases of secondary cmec have demonstrated an increased risk in patients with leukemia/lymphoma after radiotherapy.
