[Giant atypical lipoma of the thigh. Case report and literature review].

Lipomas are benign tumors of mesenchymal origin which may localize in various sites, both superficial or deep. Among the benign tumors they have an incidence of around 10%; most of them have small size and low weight (about 30 g); huge masses (giants lipomas) are uncommon. The Authors report the case of a 73 years old woman, with a large swelling localized at the anterior-medial region of the left thigh, of about three years, completely asymptomatic, surgically excised, and by histological examination, proved to be a giant atypical lipoma.
