Symmetric Lipomatosis of the Tongue: Report of a Case

A case of symmetric lipomatosis of the tongue is reported. The patient was a 72-year-old Japanese male who complained of a bilateral swelling of the tongue. The tongue of the patient was diffusely and markedly enlarged with somewhat nodular appearance in the lateral borders, presenting as a macroglossia. Histopathologically, the biopsy specimen showed adipose tissues which consisted of mature lipocytes. Partial glossectomy was performed. Adipose tissues were interspersed with the muscles fibers and distinct capsule formation was not found. The patient was finally diagnosed as having symmetric lipomatosis of the tongue based on the clinical, radiological and histopathological findings.
