[Madelung's disease. Clinical case and review of the literature].

Symmetrical benign lipomatosis (Madelung's disease) is extremely rare. Approximately 200 cases have been reported in the literature. SLB is a syndrome characterized by the occurrence of symmetric lipomas of the neck. No clear etiology has been recognized while a frequent association with systemic metabolic abnormalities has been described. The only effective therapy is the palliative surgical removal of the fatty tissue by lipectomy or liposuction. Experience with surgically treated patients shows the tendency of this disease to recur.
