Extraskeletal Ewing`s sarcoma was first reported by L. Angervall and F.M. Enzinger in 1975. Clinically the tumor affects mainly young adults and children The extraskeletal Ewing`s sarcoma are mainly involved the soft tissues of the trunk and lower extremity. Microscopically. extraskeletal Ewing`s sarcoma is indistinguishable from the Ewing`s sarcoma of bone. We recently experienced a case of extraskeletal Ewing`s sarcoma of the anterior chest wall in a 13-year old female. The patient underwent local wide excision and postoperative radiation and combind chemotherapy were done. This group of tumors has been rarely reported in Korea. We presented a case of extraskeletal Ewing`s Sarcoma in the anterior chest wall with reviw of world literature.

The Ewing`s sarcoma is the primary malignant bone tumor but the tumor also occurs as a primary soft tissue neoplasm without involvement of bone. Here is presented a case of extraskeletal Ewing`s sarcoma in the posterior and superior mediastinum with review of literature. To our knowledge, this is the first case report of extraskeletal Ewing`s sarcoma in Korea.

Ewing's sarcoma usually arises from skeletal bone, but rarely may have an extraskeletal origin. However, Ewing's sarcoma that originates around the spinal column, especially, the intradural extramedullary type is extremely rare. We report a rare case of primary intraspinal extraskeletal Ewing's sarcoma.

Ewing's sarcoma는 청소년기에 대퇴골, 척추주변부, 골반골 등의 뼈에서 흔히 발생하며 드불게 골외에서도 발생하는 종양으로서 특히 흉벽에서의 Ewing's sarcoma의 발생은 흉부 종격동 종양의 감별진단으로 고려해야 할 것으로 사료되며 광범위한 국소적인 절제와 더불어 화학요법 및 방사선 요법으로 좋은 치료 성적을 보이고 있어 골외 Ewing's sarcoma에 대한 정확한 발생부위, 예후 및 치료 방침에 대한 계속적인 연구가 필요할 것이다.

Ewing's sarcoma is an uncommon malignant neoplasm of the long bone and it has a poor prognosis due to its early metastasis and aggressive local spread. It is mostly found before the age of 30 and it is rare in extraskeletal sites. Extraskeletal Ewing's sarcoma has been reported to occur in various sites including the larynx, scalp, nasal fossa, neck, chest wall, lung, pelvis, perineum, arm, finger, leg and toe, but it is extremely rare as a primary epidural tumor of the spine. We experienced a case of extraosseous epidural Ewing's sarcoma arising in the lumbar spinal canal at L3-L5 level in a 9-year-old boy. Following total laminectomy from L3 to L5 with a lumbar vertebrae and mass excision, he received chemotherapy with complete remission.

Recently we experienced four cases of soft tissue Ewing sarcoma, developed in the calf muscles in two cases, and one case each in the foot and suprascapular region. We also found that the clinical course in all cases was rather rapid, because of local recurrence and metastatic lesions developing within a few months, followed by the patients' death in about 2 years after the primary tumor was excised. These cases were improperly treated initially as some kind of benign soft tissue tumor. The delay led to missed early accurate diagnosis and was thought to be one of the main causes for the rapid local recurrence and metastasis after tumor excision. The pulmonary metastasis was the most common cause of death.

The traditional methodology in Ewing's sarcoma was chemotherapy and radiotherapy. Recently surgery is reemerging as an important therapeutic tool and some paper report increased survival with it. The purpose of this nonrandomized study is to evaluate our result of Ewing's sarcoma with surgery, retrospectively. We experienced 30 cases for seven years and among them 6 were extraskeletal. In location, axial was 10 cases and peripheral was 20. By Enneking's classification, state IIB was 26 cases and IIIB was 4. Eighteen patients took operation, chemotherapy and/or radiotherapy, and remaining twelve took chemotherapy and/or radiotherapy only. Type of operation was limb salvage in 16 cases and amputation 2. Average dosage of radiation was 45.1Gy. Six kinds of chemotherapeutic regimen were used, but among them main protocols were Ifosfamide-Adriamycin(17 cases) and IESS(Cytoxan, Adriamycin, Methotrexate, Vincristine:8 cases). Complications were as follows. In operation group, there were 3 local recurrence and one case of nonunion. In nonoperated group, one local recurrence and one pancytopenia resulting in death. Average follow up was 29.7 months. Kaplan-Meier's ten year actuarial survival rate for the whole 30 cases was 26.8%. Significant difference in survival exists between central and peripheral lesions(p=0.05, by log rank test). Types of chemotherapy and surgery itself showed no significance. But surgery is important in function and local control. More intensive chemotherapeutic regimen to prevent distant metastasis and combined surgery and radiotherapy may be needed in Ewing's sarcoma.

Purpose: Coverage of full-thickness large flank defect is a challenging procedure for plastic surgeons. Some authors have reported external oblique turnover muscle flap with skin grafting, inferiorly based rectus abdominis musculocutaneous flap, and two independent pedicled perforator flaps for flank reconstruction. But these flaps can cover only certain portions of the flank and may not be helpful for larger or more lateral defects. We report a case of large flank defect after resection of extraskeletal Ewing's sarcoma which is successfully reconstructed with reverse latissimus dorsi myocutaneous flap. Methods: A 24-year-old male patient had $13.0{\times}7.0{\times}14.0$ cm sized Ewing's sarcoma on his right flank area. Department of chest surgery and general surgery operation team resected the mass with 5.0 cm safety margin. Tenth, eleventh and twelfth ribs, latissimus dorsi muscle, internal and external oblique muscles and peritoneum were partially resected. The peritoneal defect was repaired with double layer of Prolene mesh by general surgeons. $24{\times}25$ cm sized soft tissue defect was noted and the authors designed reverse latissimus dorsi myocutaneous flap with $21{\times}10$ cm sized skin island on right back area. To achieve sufficient arc of rotation, the cephalic border of the origin of latissimus dorsi muscle was divided, and during this procedure, ninth intercostal vessels were also divided. The thoracodorsal vessels were ligated for 15 minutes before divided to validate sufficient vascular supply of the flap by intercostal arteries. Results: Mild congestion was found on distal portion of the skin island on the next day of operation but improved in two days with conservative management. Stitches were removed in postoperative 3 weeks. The flap was totally viable. Conclusion: The authors reconstructed large soft tissue defect on right flank area successfully with reverse latissimus dorsi myocutaneous flap even though ninth intercostal vessel that partially nourishes the flap was divided. The reverse latissimus dorsi myocutaneous flap can be used for coverage of large soft tissue defects on flank area as well as lower back area.
