Primary liver sarcoma is rare and especially its coexistence with hepatocellular carcinoma is extremely rare. We have collected eight cases of their coexistence in the literatures. The patient was a 62-year-old male complaining of right hypochondralgia and general malaise for about one month. CT scanning revealed the liver tumor and right hepatic lobectomy was performed. The tumor was sized in 14 by 9 by 9 cm and composed of hepatocellular carcinoma and rhabdomyosarcoma, which were were collided. Apparent striations in the rhabdomyosarcoma cells was observed under light-microscope. Alphafetoprotein, of which serum level was extraordinarily high, was detected only in hepatocellular carcinoma by special stains. He discharged one month after operation. He was readmitted due to recurrence and received trans-arterial embolisation therapy and systemic chemotherapy. Though transient effect was obtained. He died forty-five days after operation. Autopsy revealed that recurrent liver tumors consisted of only hepatocellular carcinoma and that no other tumorous lesion was found in the other parts of the body. Rhabdomyosarcoma was proved to be primary tumor the liver.

Primary sarcomas of the thorax are rare. The diagnosis is established only after sarcomalike primary lung malignancies and metastatic disease have been excluded. Primary sarcomas of the thorax are classified according to their histologic features and constitute a large group of tumors that occur in the lung, mediastinum, pleura, and chest wall. Angiosarcoma, leiomyosarcoma, rhabdomyosarcoma, and mesothelioma (sarcomatoid variant) are the most common primary intrathoracic sarcomas. Ewing sarcoma, primitive neuroectodermal tumor, chondrosarcoma, malignant fibrous histiocytoma, osteosarcoma, synovial sarcoma, and fibrosarcoma usually arise in the chest wall. Although primary thoracic sarcomas commonly manifest as large, heterogeneous masses, they have a wide spectrum of radiologic manifestations, including solitary pulmonary nodules, central endobronchial tumors, and intraluminal masses within the pulmonary arteries. The different histologic types of sarcomas are frequently indistinguishable at radiologic analysis. However, differences in clinical presentation and the location of the tumor, as well as morphologic features such as calcification within the mass and rib involvement, can be useful in suggesting the appropriate diagnosis. For example, a large rib mass in a child with fever and malaise indicates a Ewing sarcoma, a mass with a calcified matrix is likely a chondrosarcoma or osteosarcoma, and a pulmonary artery mass is likely a leiomyosarcoma.
