[Malignant soft tissue tumors]

This article is a survey of actual aspects. With regard to frequency, the malignant fibrous histocytoma comes first, followed by lipo- and fibrosarcoma, synovial sarcoma, malignant schwannoma, malignant tumours proceeding from arteries and veins and the unstriated musculature. Staging and grading of these tumours are difficult. Until now their overall TNM-classification was not possible due to insufficient hard criteria.
