摘      要：BACKGROUND:Primary hepatic carcinosarcoma is a rare malignant tumor containing an intimate mixture of carci- nomatous and sarcomatous *** on risk factors, epidemiology,and pathogenesis of the tumor as well as the experience in its treatment are limited. METHOD:We present a case of primary carcinosarcoma of the liver in a 69-year-old man who complained of right hypochondrial pain and weight loss for two months. RESULTS:Magnetic resonance imaging revealed a 14×12 cm mass in segments 7-8 and 4 of the liver with vena hepatica *** ultrasonography-guided biopsy showed osteoid tissue without osteoblastic *** structures accompanied the osteoid *** patient underwent surgery after a diagnosis of *** frozen sections revealed a carcinosarcoma associated with an osteosarcoma and cholangiocellular carcinoma components. CONCLUSIONS:Preoperative diagnosis of this rare primary hepatic malignant tumor may be difficult by biopsy owing to intratumoral *** mature areas of the osteosarcomatous component may lead to misdiagnosis of metaplastic bone *** features of this rare entity are discussed.
