The lesion is characterized by a band-like semicircular depression, 2-4cm in width on the anterolateral aspects of the thighs. The overlying skin is normal. Usually, there are no subjective symptoms. There is no treatment, but most cases resolve in a few years. We experienced a typical case of semicircular lipoatrophy in a 43 years old woman. The patient showed an unilateral semicircular depressed lesion on the anterolateral aspect of the right thigh. Histopathologically, the lesion exhibited decrease in size of the individual adipocytes.
