Abstract

In 52 cases of fibrohistiocytic sarcoma activity of alfa-1-antichymotripsin (ACT) in tumour cells was found in 47 cases and lysozyme in 16 cases. ACT was found in all types of tumour except angiomatous. Lysozyme was positive only in pleomorphic type, all these cases have also activity of ACT. Investigated enzymes are useful in diagnosis with correlation to others markers used in diagnostic procedure of soft tissue tumours.
