Semicircular lipoatrophy is a new entity with horizontal depressions involving half the circumference of thigh, on the antero-lateral aspect. After seven female patients we observed this condition for the first time in the male. Therefore semicircular lipoatrophy is not specific to the female. The cause could not be determined clinically, nor by biochemical, immunological or histological methods. In our opinion semicircular lipoatrophy represents an ischemic atrophy of the fatty tissue, manifested by repeated microtraumata (corners of wash-basins, dressing tables or desks). The perfusion on the antero-lateral aspect of the thighs is tenous, especially when the course of the lateral femoral circumflex artery varies from the normal. In this case semicircular anastomotic areas become ischemic and horizontal bands of lipoatrophy result.
半圆形脂肪萎缩是一种新的病症，其特征为大腿前外侧出现水平凹陷，累及大腿周长的一半。在观察了七名女性患者后，我们首次在男性中发现了这种情况。因此，半圆形脂肪萎缩并非女性特有的病症。临床、生化、免疫或组织学方法均无法确定其病因。我们认为，半圆形脂肪萎缩代表脂肪组织的缺血性萎缩，表现为反复的微创伤（洗脸盆、梳妆台或书桌的边角）。大腿前外侧的灌注较为薄弱，尤其是当旋股外侧动脉的走行与正常情况不同时。在这种情况下，半圆形吻合区域会出现缺血，进而导致脂肪萎缩的水平带形成。
