A case of pantaloon obesity

A 79-year-old woman presented with an unusual form of obesity limited to the lower half of the body from the waistline down but sparing the lower legs and feet. The patient was massive (360 lbs) and symmetrical. The superior half of the body was normal with no morbid obesity or lipoatrophy. These findings do not correspond to any classic form of lipodystrophy. The fat distribution is reminiscent of a pair of knickers and qualifies for the name "pantaloon obesity."
