[Massive localized lymphedema]. / Lymphœdèmes massifs localisés.

BACKGROUND: Massive localized lymphedema (MLL) is a benign soft-tissue lesion that usually presents as a large and isolated mass in morbidly obese adults. PATIENTS AND METHODS: We report the case of a 39-year-old woman presenting obesity and multiple MLL. There was a large tumor in the left groin and two smaller lesions on the backs of the thighs. DISCUSSION: MLL is a benign tumor that must be removed wherever possible because such tumors may degenerate into angiosarcomas in 13% of cases. MLL is probably secondary to a prolonged obstruction of lymphatic vessels due to marked excess of adipose tissue.
