Lipomas are common soft tissue that are usually located in the subcutaneous tissue. And intramuscular lipomas commonly arise in the upper and lower extremities, where they usually involve the large muscles. Intramuscular lipoma, also referred to as an infiltrating lipoma, is an unusual benign slow growing tumor composed of mature fat cell interdigitating with skeletal muscle. However, intramuscular lipomas are exceedingly rare in the face. We have been experienced a case intramuscular lipoma that located in the malar area. Because of the rarity of these tumors and their propensity to recur without adequate surgery, the case report is presented here. Achievement of surgical margin is essential as the recurrent rate may be as high as 15% to 62.5% without complete excision.

Computed tomographic (CT) scans of 46 jaundiced patients were studied to determine the value of CT in the diagnosis of biliary pathology. AII ofthe 12 cases of medical jaundice had positive CT correlation. Of the 34 cases of proven surgical jaundice, 97 .8% were correctly identified by CT. In detecting the level of obstruction, the cases were divided into four groups by anatomica l segments, according to the number of visualized low density ringlike structures produced by dilated bile duct. All of the correctly diagnosed surgical jaundice was 91.2%. The presence of stones or mass, the level of obstruction and the relative size and shape of visualized distal ring had proved to be the most important variables in etiological diagnosis of surgical jaundice. The results indicate that CT is useful and highly accurate in differenting between surgical (obstructive) jaundice and medical (non-obstructive) ajundice, and determining the level of obstruction and the etiology of surgical jaundice.

Although many invasive studies in the biliary tract disase are replaced by noninvasive techniques such asultrasonography and CT, PTC does still play an important role indiagnosis of obstructive jaundice. Authors hadperformed 42 patients of PTC with Chiba needle at the department of radiology, Han Gang Sacred Heart Hospital for4 years from Jan. 1978 to April 1982. And we reviewed literatures. The results were as follows; 1. Forty twopatients of PTC were 22 males and 20 females. The success rate was 90.5%(38/42). The failed 4 cases of PTC werenonobstructive hepatobiliary diseases. 2. The PTC diagnosis of 38 cases were biliary stone (21 cases),cholangiocarcinoma(7 cases), pancreatic carcinoma (2 cases), hepatoma (2 cases), ascariasis(2 cases), andclonorchiasis(1 case), and the remainders were normal. 3. We made 2 cases of misdiagnosis on the basis of PTCfindings. They were one case of distal CBD stone with severe cholangitis diagnosed as ampullary carcioma andanother case of proximal CBD stone with cholangitis diagnosed as pancreas carcinoma. 4. We experienced 2 cases ofcomplication such as sepsis and severe hypotension, but they were recovered.

The total knee replacement is an excellent method for the treatment of osteoarthritis, rheumatoid arthritis, etc. of the knee joint. The tendency of the use of total knee prosthesis is increasing now in Korea. But domestic production of the prosthesis is not avaliable and all are imported from abroad. Moreover, these prosthesis are not well adapted to Korean people, and in occation, the custom-made prosthesis should be needed. So, domestic production of the prosthesis is required. For production of new prosthesis, in cooperation with KAIST(Korea Advanced Institute of Science and Technology), we developed the new alloy 15-57 for total knee prosthesis. We conducted an animal experimental study to confirm the biocompatibility of the new alloy. In this experiment, the Zimmer® company vitallium was compared with this new alloy as control study. The results are as follows: 1. Biocompatibility of the new alloy 15-57 is similar than that of Zimmer® company vitallium in histological study of metal-bone interspace area. 2. Surface corrosion of both metal was nearly absent. 3. In summary, the new alloy 15-57 is suggested as an acceptable metal for the production of total knee prosthesis.

Pathologic fracture is a bresk of bony continuity within an abnormal bone. The abnormslity ma be due to systemic skeletal disease, infection, primary benign and malignant tumor, or metastati carcinoms. Among these, metastatic carcinoma to bone is most common cause of pathologic fractur excluding those due to osteoporosis. When considering the msnagement, pathologic fractures due to systemic skeletal disease usually heal with conservative treatment, while others often require operative treatment. We have experienced 20 cases of pathologic fracture in long bones for 8 years from 19 to 1987. The results were as follows ; 1. The average sge was somewhat different according to underlying diseases Malignant tumorous lesion; 53 years Benign tumorous lesion ; 17 years Chronic osteomyelitis, 42 years 2. The most common cause was malignant tumorous lesion, 8 cases(40%). 3. The most frequent site was femur, 17 cases(85%). 4. Surgical treatment was done in 17 cases(85%), and conservative treatment was done in 3 cas(1sw). 5. In 3 cases of pathologic fractures due to metaststic tumor, the pain was markedly relieved and essy nursing care was possible immediately after operation.

In this retrospective study, 49 patients who were treated by surgical resection of colorectal cancer, confuted to proper muscle and confirmed histologically from 1979 to 1996 were included. To examine the significance of growth pattern in terms of polypoid growth(PG)(n=26; m,sm 5, pm 21) and non-polypoid growth(NPG)(n=23; m,sm 3, pm 20), we analyzed several clinocopathologic variables by x2 test and unpaired t-test, 5-year survival rate by Kaplan-Meier method and Log-Rank statistics according to growth type comparatively: 1) In the PG tumor, muscle elevation(P<0.0117) and association with adenoma(P<0.0001) were more frequent than in the NPG. 2) The NPG type showed smaller size(P<0.0172) and higher rate of lymph node metastasis(P=0.025) and higher tendency of lymphatic invasion(P=0.07) and poor differentiation(P=0.0693) and deeper invasion(P=0.0972) and worse 5-year survival(P=0.0607). 3) Otherwise there was no difference in inflammation, fibrosis, and angioinvasion. 4) The mean thickness of Outer Longitudinal Muscle(OLM) was thicker in rectum than colon(rectum 1.62 mm, colon 0.74 mm, p<0.0059) and pm cancer was more in rectum than in colon(rectum 10.3%, colon 4.0% , p=0.0057). In the view of results, NPG in early colorectal cancer may suggest the possibility of de novo cancer. NPG type was smaller in the size but more aggressive in lymph node metastasis, lymphatic invasion, invasion depth, tumor differentiation, 5-year survival rate. So it needs more thorough follow up. The higher incidence of pm cancer in rectum than in colon, is probably due to thicker OLM of rectum than that of colon.
