Several histologic variants of lipomas, eg, fibrolipoma, angiolipoma, myelolipoma, SCL, and pleomorphic, myxoid, atypical, and infiltrating lipomas, have been described in the literature. In 1975, Enzinger and Harvey1 described SCLs as neoplasms of adipocytes. Thirteen percent of SCLs occur in the head and neck region, although SCLs account for only 1.5% of all lipomatous tumors.2 Classically, they occur in elderly men and are typically found on the posterior aspect of the neck, shoulders, and back. Fifteen cases, however, have been reported in the oral cavity. Reports of tongue involvement are even rarer, and to our knowledge, only 7 cases have been reported in the literature.3
