Lipoatrophia semicircularis is a peculiar variety of localized lipoatrophy, characterized by horizontal, band-like, semiannular depressions, simmetrically distributed on the anterolateral aspects of the thighs. It occurs predominantly in young women in their twenties and thirties. The lesions develop quickly and usually resolve within 9 months to 4 years, although long-lasting cases and recurrences are possible. A case of lipoatrophia semicircularis in a 23-year-old female secretary is reported. She presented with two asymptomatic, horizontal, semicircular depressions on her left thigh, that had been first noticed 4 months before. The overlying skin was normal. When carefully inquired about trauma, she realized that the skin depressions coincided precisely with the edge of a desk, where she pushed her left thigh every time she stood up or crossed her legs. The lesions disappeared 9 months later, avoiding trauma. The current literature on the subject is reviewed, pointing out the clinicopathological features of the disease and its differential diagnosis. Finally, recent data on etiology are reported and discussed.
