Lung A malignant tumour having a mixture of carcinoma and sarcoma, the latter containing heterologous elements such as malignant cartilage, bone or skeletal muscle (WHO 1999).
Urology A rare malignant tumour that is more common in older males—70 cases reported in the world literature. It presents in advanced stage, is a rapidly growing polypoid tumour and has a poor prognosis. The epithelial component is usually a high-grade transitional cell carcinoma with epidermoid and/or glandular differentiation. The heterologous component consists of chondrosarcoma, malignant fibrous histiocytoma, osteosarcoma, leiomyosarcoma, fibrosarcoma, or rhabdomyosarcoma
