Purpose: Lipomatous tumor occurred in hand is very rare. There is a broad spectrum of lipomatous tumors including lipomas, variants of lipomas, lipomatosis, liposarcomas and so on. We report the clinical features of 11 cases of lipomatous tumor which occurred in hand. Materials and Methods: Between 1992 and 2008, 11 cases were histologically diagnosed as lipomatous tumor in hand. We reviewed all medical records and clinical photographs retrospectively and ascertained recurrence by telephone interview. Results: Eight cases were ordinary lipomas. Three cases were angiolipoma, fibrolipoma and atypical lipoma respectively. Four cases occurred in finger, two cases in thenar area, two cases in hypothenar area, one case in palm, two cases in wrist. All cases were situated on volar surface. All patients complained of palpable masses. One patient with subungal angiolipoma felt pain. There was no neurologic sign or vascular symptom preoperatively. In one case, postoperative complication (hypoesthesia in $5^{th}$ finger) was developed. There was no local recurrence. Conclusion: In our study, lipomatous tumors occurred in hand did not recur. Patients mainly complained of feeling of lump. Pain was uncommon symptom. Postoperative complication was rare if operation was performed carefully.

지방종은 아주 흔한 양성종양이지만 흉막에서 발생한 지방종은 드물다. 대부분 무증상이며 우연히 발견되는 경우가 많다. 단순 흉부 X-선 사진상 양성종괴의 모습을 보이며, 전산화 단층촬영에서 특징적인 균질한 지방으로 구성된 종양의 모습을 보인다. 흉막의 지방종의 경우 다른 종양이나 악성 종양을 배제하기 위하여 개흉술을 통한 종양의 제거를 해왔으나 수술 후 통증이 적고 회복이 빠른 흉강경으로 지방종을 제거한 53세 여자환자 1례를 경험하였기에 보고하는 바이다.

It is well understood that liposarcoma is most common in soft tissue sarcomas. It usually develop proximally in the extremities and most patients are older than 50 years. We report a case of huge liposarcoma which develop on left thigh of 67-year-old man. There was no evidence of metastasis and the tumor was successfully removed by marginal resection. Patient's height is 153 cm and weight is 43 kg, but the tumor's size is $34{\times}20{\times}9\;cm$ and weight is 2.82 kg. The Mass is severely huge in compare with patient's height and weight. But, There are few reports regarding the correlation between tumor-size and pathologic differentiation. Pathological examination reveals a well differentiated liposarcoma. The patient is still asymptomatic at 6-months follow up.

지방모세포종은 태생기 지방조직에서 기원하는 드문 양성종양으로 대부분 소아기에 발생하는데 이 종양의 약 70%는 사지에서 나타나고 간혹 다른 부위에서 보고되기도 한다. 저자들은 좌측 후종격동과 좌측 쇄골상부에 양성 지방모세포종을 보인 3세된 남아를 치험한바 있다. CT 소견상 지방을 함유한 종괴가 정상적인 흉강내 구조물을 누르고 있었고, 쇄골상부 및 종격동으로부터 합병증없이 절제되었다. 종괴는 황색을 띠었으며, 병리조직검사상 지방모세포종으로 진단되었다.

Forty-two preoperative CT scans with renal cell carcinoma were reviewed and compared with pathologic findings to evaluate the differential points between stage I and II. Regardless of whole body staging, perirenal fat infiltrations were seen in 9 cases and the other 33 cases showed no infiltration onto perirenal fat tissue. We retrospectively reviewed them by comparing tumor size and CT findings, following three view points, lobulating contour of tumor margin, thickening of Gerota's fascia and strands in perirenal fat tissue. The size of them was 2-15 cm, size of the stage I tumors was 2-15 cm and that of stage II was 6-15 cm. In stage I(n=33), 25 cases(76%) showed smooth margin, and the others(n=8) showed lobulating contours. Thickening of Gerota's fascia was observed in 7 cases(21%) and strands in perirenal fat tissue in 14(42%). Of these, only one positive finding was seen in 7 cases(21%), 2 findings in 6(18%), 3 findings in 3 (9%) and nothing in 17cases(51%). In stage II(n=9), 3 cases(34%) showed smooth margin, and the others(n=6) showed lobulating contours. Thickening of Gerota's fascia were observed in 5 cases(55%) and strands in perirenal fat tissue in 9(100%). Of these, one finding was seen in 2 cases(22%), 2 findings in 3(33%), 3 findings in 4 (44%). In conclusion, it is insufficient to evaluate the perirenal fat infiltration in renal cell carcinoma with only one positive finding of 3 view points; lobulation of tumor margin, thickening of Gerota's fascia, strands in perirenal fat tissue. But if all these findings are shown, it is helpful to determinate perirenal fat infiltration of renal cell carcinoma.

The primary mediastinal liposarcoma is a very rare tumor. It mainly causes respiratory symptoms, but can be asymptomatic. The most favorable treatment of primary mediastinal liposarcoma is a surgical removal, whether it is complete or not, regardless of the size or histologic type of the tumor. The survival is determined by the histologic type of tumor. A 34-year- ld man was admitted because of asymptomatic mediastinal tumor which was progressively growing over 6 years. The tumor was completely resected and the microscopic findings of the tumor were compatible with well-differentiated liposarcoma. The patient recovered and discharged without complication on the 7th postoperative day.

Myxoid liposarcoma is an extremely rare malignant breast tumor. We report the case of a 44-year-old woman who had myxoid liposarcoma of the breast with a history of phyllodes tumor and describe the imaging findings on US, mammography, and MRI. Before surgery, the mass was considered to be a recurrent phyllodes tumor. However, using US, we retrospectively identified some differences between myxoid liposarcomas and phyllodes tumors.

Lipomas are the commonest soft tissue tumor. However, those arsing in the hand are infrequent. Lipomas in the hand that exhibit a size of more than 5 cm call giant lipoma, these are very rare only case reports and small series of this entity have been described. We could experience a case about giant lipoma of the hand which cannot easily contact, we report a case including review of literatures.

Purpose: We analyzed disease free survival and the prognostic factors of liposarcoma in the extremity. Materials and Methods: Between 1994 and 2005, of 44 patients who were diagnosed and treated for liposarcoma of the extremity, 40 patients were restrospectively analysed. 13 out of 40 patients got postoperative radiotherapy. We examined local recurrence, distant metastasis and disease free 5-year survival rate. We also analyzed clinical prognostic factors, such as age, gender, size of tumor, prior unplanned excision, histologic type, surgical excision margin and postoperative radiotherapy respectively. Results: There were 3 cases of local recurrence and 4 cases of distant metastasis. The disease free 5-year survival rate was 85.0%. 26 patients presented with myxoid, 8 well differentiated, 4 round cell, 1 pleomorphic and 1 dedifferentiated histology. The disease free 5-year survival rate of mixoid, well differentiated and round cell liposarcoma were 100.0%, 84.6% and 75.0% (p=0.419). The 5-year disease free survival rate was 90.6% in negative surgical margin (n=25) and 62.5% in positive surgical margin (n=15) (p=0.003). Conclusion: Our study suggests that surgical excision margin is significant prognostic factor for 5-year disease free survival rate.

Chondrolipomas, which are lipomas with chondroid metaplasia, are rare benign soft tissue tumors with no relevant epidemiological reports or radiological information. A limited number of lipomas with osteo/chondroid differentiation have been reported in the literature between 1960 and 2008. Moreover, only few studies have described the radiologic findings of chondrolipomas. Herein, we present a case of chrondrolipoma arising from the left supraclavicular region in a 77-year-old female.
