Abstract Unusual fat distribution of the lower part of the body is clinically characterized by massive symmetric and diffuse fat deposition in the trochanters, groins, buttocks, hips, and lower extremities, which contrasts sharply with the normal upper part of the body. The massive lipomatoses of the lower part of the body can be classified into 3 types: type 1, the familial symmetrical lipomatosis that affects the groins, trochanters, hips, buttocks, and thighs; type 2, the bilateral peritrochanteric familial lipomatoses; and type 3, the unilateral peritrochanteric lipomatosis. This unusual adiposity runs in families and predominantly exists in the Mediterranean region, and seems, however, to be common in North Africa. It is rarely reported in the literature. In this regard, a differential diagnosis is presented regarding the lipomatosis and lipodystrophies-described syndromes to familiarize plastic surgeons with these unique deformities. Between 2000 and 2006, 50 women with abnormal diffuse fat deposits in the lower part of the body were investigated and treated with conventional liposuction; patients' ages ranged between 20 to 46 years. Laboratory examination includes the serum concentrations of lipoprotein, cholesterol, triglycerides, uric acid, fasting glucose, and other routine laboratory tests. Endocrinologic tests include serum estradiol and testosterone levels, and thyroid function tests. Histologic examination of the lipoaspirate was performed. All cases were treated with liposuction. For type 1 cases liposuction was performed in stages; the maximum amount of lipoaspirate per setting was 3,000 to 4,000 mL, and for type 2 and type 3 a single stage liposuction was undertaken. Laboratory examination showed normal values and routine parameters were within normal limits. Endocrinologic investigations revealed no abnormalities and histologic examination of lipoaspirate showed normal subcutaneous fatty tissue. The esthetic outcome of all individuals was satisfactory. Abnormal swelling of the lower half of the female body caused by deposition of subcutaneous fat is determined by heredity and seems to be common in North Africa. It is often accompanied by a psychological reaction due to the disturbed body image. A clinical classification is reported in the current study. The traditional liposuction is the treatment of choice for these esthetic deformities.
