A case of symmetrical lipomatosis of the tongue presenting as macroglossia

Lipomas are the most common benign soft tissue mesenchymal tumours composed of mature adipose tissue. They are uncommon in the oral and maxillofacial regions, with 15-20 % of cases involving the head and neck region and less than 5% of all benign oral lesions. Multiple symmetric lipomatosis is rare and characterized by diffuse growth and nonencapsulated lipomas. It is usually found in the posterior neck and upper trunk and they are relatively infrequent on the oral and maxillofacial regions like Madelung disease. In the report, we describe a rare case of symmetrical lipomatosis of tongue with OSAS and Dysartria. This lesions were resected under general anesthesia. Intraoperative findings revealed only adipose tissues with replacement of lingual muscles and no capsulation. The lesion was finally diagnosed as symmetric lipomatosis of the tongue based on clinical radiological and histologic examination. SLT (Symmetrical lipomatosis of the tongue) is an extremely rare case that appears like a macroglossia. Partial glossectomy is the treatment of choice because of the improvement of symptoms and the low rate of recurrence.
