Primary osteoliposarcoma of bone.
Radiologic and pathoanatomic findings in two patients with the very rate primary osteoliposarcoma of bone are reported. In one case, there was a manifestation on the left femoral shaft which led to pathologic fracture. Amputation of the femur was followed by a 2.5-year tumor-free interval. In the second case, there was a manifestation in the region of the right upper part of the ilium. After radiation and cytostatic therapy, pronounced intratumoral ossifications occurred and the patient's condition was good up to exitus lethalis 3 years after diagnosis. Osteoliposarcoma thus shows a markedly more favorable prognosis than the osteosarcoma and rather corresponds to that of a liposarcoma. Typical clinical and radiologic symptoms are lacking.
