<unk>  is the most frequent lipogenic lesion of bone. Patients range in age from 5 to 85 years, with the lesions being most frequently discovered in the 4th and 5th decades of life. Males are slightly more commonly affected than females. Although<unk>  lesions may be discovered incidentally, pain has been reported in up to 66% of cases. Pain may be mechanical due to expansile remodeling of bone or it may be related to the ischemic changes that frequently accompany these lesions. Frequent locations include Intertrochanteric region (34% of cases), Calcaneus (8%), Ilium (8%), tibia (13%), fibula (10%), humerus (5%), and ribs (5%). Long bone lesions typically occur in the metaphysis. Typically are solitary lesions. Treatment of<unk> s is often not indicated with asymptomatic lesions or those discovered incidentally. Symptomatic<unk> s may be treated with curettage and bone graft placement.
