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.

Malignant fibrous histiocytoma (MFH) is a pleomorphic soft tissue sarcoma. Three cases of MFH were reported in our study. The first case involved in the right infratemporal fossa of a 32-year-old female was presented. MR imaging revealed a 5.0 × 3.3 cm soft tissue mass of inhomogeneous high signal intensity. The second case was found in the right hard palate of a 66-year-old male. CT demonstrated bone destruction and MR imaging showed a 4 × 4 cm sized soft tissue mass of heterogeneous high signal intensity. The final case was found in the left masticator space of a 37-year-old male. The CT image showed a large mass with massive bone destruction of the left mandibular ramus, while the MRI displayed a soft tissue mass, 8 cm diameter. Our cases exhibited the general features of MFH. MRI is essential in the imaging of MFH, namely to depict tumor borders and demonstrate relationships with adjacent structures.

A total of 44 patients with extremity soft tissue sarcomas had received conservative surgery and radiation therapy in the Department of Radiation Oncology, Yonsei Cancer Center, Yonsei University College of Medicine between Jan. 1980 and Dec. 1990. Initial surgical treatment consisted of intracapsular excision in 33 patients $(75\%),$ marginal excision in 9 patients, and wide excision in two patients. Total radiation doses were between 40Gy and 65Gy (median 60 Gy). Median follow-up period was 47 months. Overall actuarial 5-year survival rate was $76.9\%$ and 5-year recurrence free survival rate was $39.3\%.$ There was no statistically significant prognostic factors but the 5-year survival rates tended to be decreased in the patients with high grade tumors and treated with narrow surgical extent. Sixteen patients recurred during fellow-up (16/31, $51.6\%).$ The incidence of initial local recurrence was $22.6\%$ (7/31) and distant metastasis was $29\%(9/31).$ Of the 7 who did not have metastasis at diagnosis of local recurrence, 5 were submitted to a salvage treatment. All of them achieved local control and distant metastasis appeared in three of them. In conclusion, conservative surgery and radiation therapy in the patients with extremity soft tissue sarcomas was the effective treatment modality.

The desmoid tumor has been reported as the most common histologic subtype of soft tissue sarcoma occuring in chest wall and it known to be highly recurrent. The treatment of choice is a radical wide resection including a safe margin of uninvolved structures around the grossly visible tumor. We report a case of chest wall reconstruction using Marlex sandwich and latissimus dorsi musculocutaneous flap after wide resection of desmoid tumor on the chest wall.

Malignant fibrous histiocytoma is the most common soft tissue sarcoma of late adult life. The tumor occurs principally in one of the extremities or in the abdominal cavity or retroperitoneum, but very rarely in the heart. We report a case of M.F.H. that arose from the posterior wall of the left atrium. A 50 years old woman was presented with signs and symptoms of severe congestive heart failure. On 2-D echocardiographic exam, a huge mass was found in the left atrium. The mass was excised under open heart surgery. Histologic examination revealed that the tumor was actually a malignant fibrous histiocytoma.

Extraskeletal myxoid chondrosarcoma is an unusual soft tissue sarcoma with distinctive histologic features. It once was called chordoid sarcoma because it resembles chordoma histologically. The lesion has been shown to be of chondroblastic origin. This lesion shown to have ultrastructural and molecular features distinct from that of myxoid chondrosarcoma of bone. We report a case of extraskeletal myxoid chondrosarcoma in forefoot.

Rhabdomyosarcoma is the most common soft tissue sarcoma in children, accounting for 4.5% of all cases of cancer in childhood. Although the head and neck are the most common sites of rhabdomyosarcoma, oral lesions are relatively rare and account for only 10% to 12% of head and neck rhabdomyosarcoma cases. This is a case report of a girl aged 2 years and 1 month who initially presented with an upper lip mass that invaded the oral mucosa, oral skin, and nostril skin, causing narrowing of the airway. Through our case, we show that rapidly growing small round cell malignancies, especially rhabdomyosarcoma, can be effectively diagnosed and treated at the same time using primary resection with intraoperative frozen section biopsy and that the time spent waiting for the results of preoperative biopsy can be saved in this way, particularly when the patient's symptoms are intensifying rapidly and require immediate operation.

Pediatric solid tumors have many histologic similarity. These tumors contained small round cell types, and cause frequent diagnostic problems in pediatric pathology. An important advance in the differentiation of these small round cell tumors has been the identification of consistent chromosomal translocations associated with several types of tumors. Eighteen patients with soft tissue sarcoma were available for review. Seventeen cell lines were also included in this study. The RNA from the specimens were analyzed by reverse transcriptase-polymerase chain reaction (RT-PCR). PAX3-FKHR fusion was present in four of five alveolar rhabdomyosarcoma and PAX7-FKHR fusion was detected in one of five alveolar rhabdomyosarcoma. None of the specimens expressed more than one chimeric transcript. EWS-FLI1 or EWS-ERG fusions were detected in all seven Ewings' sarcoma. No specimens showed EWS-WT1 fusion. These results corresponded well to the histopathologic diagnosis. There were no differences in the histologic appearances of tumors with the more frequent PAX3-FKHR or EWS-FLI1 fusions compared with those containing the variant PAX7-FKHR or EWS-ERG fusions. RT-PCR assay for chimeric transcript is a useful tool for rapid and objective diagnosis of pediatric solid tumors. Through these tools, we can approach genetically to the differential diagnosis of undifferentiated small round tumors.
