<unk>  is a rare genetic disorder in which subcutaneous angiolipomas form around the wrists, knees, and ankles. The syndrome was first described by Sveln<unk>  et al. in 1980.<unk>  is also known as "anomalous insertion of extensor tendons of fingers". This name derives from the condition that the tendons of the fingers are attached in such a way that the fingers cannot open or close normally. Though the tumors extend deeply into the muscle tissue, joints, and tendons, the tumors did not invade these structures.
