4. 양성종양은 신체전반 연부조직에 비교적 고르게 발생하였으나 악성종양은 하지에 호발하였다.
5. 악성종양 39예 중 13예(33.3%)에서는 입원당시 이미 전이를 보였으며 이 중 8예는 폐를 전이되어 있었다.
6. 대부분의 양성종양 환자는 국소 절제술로 완전 치유되었으며 악성종양은 광범위 절제술과 방사선 및 화학요법을 병행하였다.
7. 양성종양 환자 202예 중 12예(5.9%)에서는 국소 재발을 볼 수 있었으며 특히 혈관종, 신경섬유종과 섬유종증에서 비교적 재발율이 높았다.
8. 악성종양 39예 중 치료 후 추적관찰이 가능하였던 것은 19예였으며 그 중 1년이상 생존한 것은 13예, 5년이상 생존중인 예는 2예였다.

Soft tissues, which are wide stead in body, are derived from a common primitive mesenchyme and the tumors arising from them tend to the closely resemble the prototype tissues in varying degree.
Some soft tissue tumors have benign course, which can be cured by cured excision and the others have malignant course being resistant to therapy and resulting in recurrence or metastasis to other organs or tissues.
The author reviewed 241 cases of soft tissue tumors which had been received treatment at Department of Orthopedic Surgery in Severance Hospital, Yonsei University College of Medicine from January 1972 to December 1981.
The results were obtained as follows:
1. Among 271 cases of soft tissue tumors, 202(83.8%) were benign and 39(16.2%) were malignant.
2. The most common benign tumor was lipoma(68.7%) which was followed by hemangioma(8.4%), neurofibroma(6.4%), and schwannoma(5.0%) in decreasing order of incidence. Among malignant tumors, fibrosarcoma(35.9%) and rhabdomyosarcoma(33.3%)
were the two most common ones, liposarcoma(12.8%) and Kaposi's sarcoma(7.7%) being the next common group of tumors.
3. There was no apparent sex preference in benign soft tissue tumors, but in malignant tumors, male was affected about 3 times more common than female.
4. There was no predilection sites in benign tumors, which in malignant tumors, lower extremity was predominant site of occurrence.
5. Metastasis of the malignant tumors was taken placed 13 cases(33.3%) at the time of admission, and the lung was the most frequent site of metastasis.
6. Most of the benign tumors were treated by local excision, and maligent tumors were treated by wide excision with combination of chemotherapy and/or irradiation.
7. Local recurrence of benign tumors was developed in 12(5.9%) out of 202 cases.
8. Among 19 cases, on which follow up examination had been made, 13 survived more than 1 year and 2 cases longer than 5 years after surgery.
