lipoatrophia semicircularis

German: Lipoatrophia semicircularis

Medicine. A rare, idiopathic condition characterized by semicircular impressions of the skin, mainly occurring on the thighs. It is characterized by atrophy of the subcutaneous fatty tissue at the location of the impressions. Skin and underlying muscles remain intact.
It is not yet clear what exactly causes semicircular lipoatrophy. Localized pressure on the thighs (e.g. by leaning on the edge of the desktop) or by electromagnetic fields of cables and computers in combination with low air humidity are discussed as possible causes. Spontaneous remission will occur within months without treatment.
