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

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.

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.

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 radio-therapy.
