Is lipoatrophia semicircularis induced by pressure?

Abstract

Ten patients suffering from lipoatrophia semicircularis are reported. It is suggested that pressure from a chair on the posterior aspect of the thighs, possibly in combination with direct pressure from a desk on the anterior aspect, caused the condition in these patients. Lipoatrophia semicircularis may be quite common, but most patients do not present to a dermatologist.
