[Primary retroperitoneal tumors (clinical findings in yolk sac tumor, vascular leiomyosarcoma and extraosseous chondrosarcoma)].
Primary retroperitoneal tumors (PRT) constitute about 0.02 per cent of all tumors examined in the Department of Pathology of our hospital. We report 3 cases of malignant PRT - yolk-sac tumour, vascular leiomyosarcoma and extraskeletal chondrosarcoma - selected for their histological rarity and clinical features. Recent techniques available for the diagnosis of these neoplasms and surgical treatment are discussed. The role of radio-chemotherapy is also dealt with.
