Abstract
A total of 752 soft tissue tumors were collected from surgical cases during the last ten years (348 males, 404 females) . They were classified into histological types according to the WHO International Classification. Of these materials, 380 lipoms comprised about 50 % of the entire series. Other common types were : neurinoma (68), ganglion (54), hemangioma (51), fibroma (23), giant cell tumor of the tendon sheath and P.V.S (23) . Malignant tumors included 31 cases of soft tissue tumors, 6 liposarcomas, 5 malignant fibrous histiocytomas, 4 leiomysar-comas, 4 rhabdomyosarcomas and 2 malignant schwannomas, among others. Soft tissue sarcomas were difficult to clasify. Electron microscopical and immuno-histological examination were considered to be significant for differential diagnosis of soft tissue sarcomas.
