Benign symmetric lipomatosis

Benign symmetric lipomatosis (also known as Benign symmetric lipomatosis of Launois–Bensaude, Madelung's disease, multiple symmetric lipomatosis and cephalothoracic lipodystrophy) is a cutaneous condition characterized by extensive symmetric fat deposits in the head, neck, and shoulder girdle area. The German surgeon Otto Wilhelm Madelung was the first to give a detailed description of the disorder. This condition is very rare with an estimated incidence rate of 1 in 25,000 and affects males up to 30 times more frequently than females.
