Bilateral asymmetric tongue classic lipomas.

Lipomas are most common benign mensenchymal neoplasm composed of mature adipocytes. But they are relatively infrequent on the oral and maxillofacial regions. In the present report, we report a rare case of bilateral involvement classic lipoma of the tongue. The patient was a 71-year-old man with asymmetric soft tissue nodules in both lateral borders of the tongue. The magnetic resonance imaging T1- and T2-weighted images demonstrated homogeneous high intensities similar to that of normal subcutaneous fat. The lesions were hypointense on the fat-suppressed T1 image. The tumors were resected surgically, and they exhibited the histopathologic features of classic lipomas, composed of mature fat cells. This suggests that differential diagnosis of intraoral multiple lipomatous nodules should include not only lipomatosis, but also multiple classic lipomas, notwithstanding the rare incidence of the latter.
