An autopsy case of a huge tumor in the right thorax is reported. A 71-year-old man complained of dyspnea and died after three months of hospitalization. The tumor, consisting of a circumscribed mass measuring 24 X 24 X 8 cm and weight 3.7 kg, originated from the right diaphragm and had no metastasis. Histologically, the tumor comprised multiple mesenchymal elements of fibrosarcoma, rhabdomyosarcoma, osteosarcoma and chondrosarcoma, and there was no distinct border between these different components. This tumor fulfills the criterion of malignant mesenchymoma (Stout). The histogenesis of the tumor is discussed with a survey of literature.

A 71-year-old woman who presented with left abdominal pain was found to have a noncalcified renal mass with a perisplenic extension on imaging studies. Histologically, the tumor showed predominantly malignant spindle cells with extensive osteoid and chondroid matrix production. Various growth patterns resembling rhabdomyosarcoma, malignant fibrous histiocytoma, and fibrosarcoma were also observed. Immunohistochemistry showed positive staining of the neoplastic cells for cytokeratin and focally positive staining for CD10 and CD117 (c-Kit). Electron microscopic examination revealed a poorly differentiated neoplasm with both mesenchymal and epithelial features. The tumor was diagnosed as a sarcomatoid renal cell carcinoma with overgrowth of the sarcomatoid component (World Health Organization: renal cell carcinoma, unclassified). To our knowledge, sarcomatoid renal cell carcinoma with such a broad morphologic phenotype in a single case has not been documented. Furthermore, the CD117 expression in a sarcomatoid renal cell carcinoma that was observed in this case merits further investigation.

We report a rare case of a hepatic carcinosarcoma with rabdomyosarcomatous differentiation in its sarcomatous component. A 71-year old Caucasian female patient underwent a liver resection for a 4-cm lesion developed on an underlying HCV-related cirrhosis. Post-operative course was uneventful and the patient was discharged 5 days after surgery. At pathology, the tumor presented the features of hepatocellular carcinoma and rhabdomyosarcoma Three months later the patient experienced a liver recurrence, dying 2 months later for systemic disease. The reported case presents several peculiarities, i.e. the female gender, the HCV-related cirrhotic status, and the European origin of the patient. However, the outcome of our case confirms that this neoplasm pursues a highly aggressive course with poor prognosis.
