Malignant fibrous histiocytoma of soft tissue

ABSTRACT

Malignant fibrous histiocytoma is a common soft tissue sarcoma characterised by mixed fibro-histiocytic cells and storiform pattern. Its frequency in Egypt to other soft tissue sarcomas has not been previously reported. A retrospective study was done on 70 cases of soft tissue sarcomas registered at the Department of Pathology, National Cancer Institute of Cairo University. The records as well as the pathologic material of this series were revised. Out of these 70 sarcomas, twelve showed the morphological, features of malignant fibrous histiocytoma; a relative frequency of 17.1. Ten cases were previously mistyped as fibrosarcoma, rhabdomyosarcoma and other sarcomas. The tumors were located at the lower limb [8], retroperitoneum [3] and head and neck regions [1] .Their sizes varied from 1 cm. to 15 cm. The average patient's age was 50.6 years, and the male sex predominated [11 1]. The management and prognosis of this recently recognised tumor is outlined
