Abstract

By Enzinger and Weiss classification, 664 cases of soft tissue tumors, which were confirmed histologically at the department of pathology of Hangang Sacred Heart Hospital from Janusry 1979 to December 1988, were analyzed statistically. The results were as follows : 1. Of the 664 cases, 261 cases (39.3%) were consulted at the Department of General Surgery, 124 cases (18.7%) were consulted at the Department of Orthopedic Surgery, 115 cases (17.3%)were consulted at the Department of Dermatology. 2, Of the 664 cases, 631 cases (95%) were benign and 33 cases (5%) were malignant. 3. The most common benign tumor was lipoma, which was followed by hemangioma and lymphangioma. Among malignant tumors liposarcoma was the most common one, followed by malignant fibrous histiocytoma. 4. The distribution of age of benign tumor was relatively even from childhood to old age but that of malignant tumor showed highest prevalence in 7th decade. 5. The distribution of sex of benign tumor showed male to female ratio of 1: 1.1 but that of malignant tumor showed male to female ratio of 1.5: l. 6. The predilection sites of benign tumors were head, neck and trunk, but those of malignant tumors were lower extremities and trunk. 7. Kinds of soft tissue tumors consulted at the Department of Dermatology were hemangioma, neurofibroma, lipoma, dermatofibroma, ymphangioma, leiomyoma, juvenile xanthogranuloma, xanthoma, keloid and neurilemmoma.
