Of 259 hemophiliacs bone pseudotumors were diagnosed in 11 (4.3%); they were localised in the femur (6 cases), calcaneus (4) and in the iliac bone (3). Two cases of combined femoral and calcaneal lesions and 4 cases of bone fracture were observed. As a rule, pseudotumors developed in hemophiliacs with severe disease. An x-ray picture of a pseudotumor depended on its site and was characterized by a large soft tissue tumor shadow, often with calcinosis, and serious destructive changes in bones in the form of round foci of 7 cm in diameter with clear-cut contours. An edge defect of the cortical layer was defined in the diaphysis of the femoral bone (15 cm long). Destructive changes were often accompanied by osteosclerosis and periostitis.
