Simultaneous occurrence of primary carcinoma and chondrosarcoma in the liver. A case report and a review of the literature.

We treated a 67-year-old man with primary carcinoma and sarcoma arising from the different areas of the cirrhotic liver. Histologically the carcinoma was of hepatocellular origin and the sarcoma consisted mainly of poorly differentiated mesenchymal cells partly with a chondrosarcomatous component. Among nine similar cases reported in the literature, only one was a rhabdomyosarcoma and the others were described simply as of spindle cell variety without evidence of mesenchymal differentiation. In the present case, the sarcoma consisted of mesenchymal cells with distinctive areas of unequivocal chondrosarcoma.
