Lipomatous tumors represent a common group of neoplasm in adult life usually presented as a mass. Authors reviewed 872 benign liopmatous tumors and 39 liposarcomas in the Department of pathology, SNUH during last 10 years (1978-1987). Among the benign lipomatous tumors, the ordinary lipomas consisted of 80.8%, followed by angiolipomas (11.4%), fibrolipomas (2.3%), intramuscular lipomas (1.8%), and angiomyolipomas (1.4%). Most of the benign lipomatous tumors occurred at adult life and were rare in infancy and childhood except for lipoblastoma. In our series, the peak age of liposarcoma at the time presentation was 50 to 60 years, and the youngest age was 17 years. The myxoid type was the most common and it accounted for 38.5% of the cases. The two major sites were the extremities and retroperitoneum. Thirteen cases out of 39 liposarcomas had recurred and 2 cases had lymph node metastases at the time of presentation.

BACKGROUND: The FcgammaRII receptor, the only kind of Fc receptor in the platelet, plays important role for immune-complex mediated platelet activation, which occurs in Heparin induced thrombocytopenia(HIT) or antiphospholipid syndrome. The purpose of this research is to find out the role of gamma-subunit in FcgammaRII signal transduction of platelets. METHODS: After cross-linking the FcgammaRII receptors with IV.3 anti FcgammaRII specific antibody and Rabbit anti mouse antibody, we made the platelet lysate in the RIPA EDTA lysis buffer condition, and performed anti gamma-subunit immunoprecipitation. After polyacylamide gel electrophoresis and Western transfer, we probed the nitrocellulose membrane of gamma-subunit immunoprecipitate with anti gamma-subunit antibody. RESULTS: The mobility shift of gamma-subunit was observed upon FcgammaRII cross-linking. CONCLUSION: The gamma-subunit is activated upon FcgammaRII cross-linking, which means the gamma-subunit is involved in FcgammaRII signal transduction of platelet.

Clinical observation was made on 6 cases with Acromioclavicular separation who were treated conservatively at the Department of Orthopaedic Surgery, Pusan National University Hospital. 1) The authors experienced good functional results in those cases with conservative treatment. 2) Closed method is desirable for grade I & II acromioclavicular separation as primary treatment and also, even for grade III depending upon the situation. 3) The authors recommended the convenient Kenny-Howard sling halter as a conservative treatment in Koreans who refuse operation.

Histopathologic and immunohistochemical analysis using antibodies for S-100 protein and keratin has been conducted on 21 cases of malignant schwannomas. The 21 cases were divided into the following three groups Group A: tumors originating from the nerve trunk or neurofibroma; Group B: tumors related to von Recklinghausen's disease; and Group C: other tumors not belonging to the above groups but histologically diagnosed as malignant schwannoma. The commonest histological pattern consisted of either closely packed or loosely arranged interlacing fascicles of slender spindle cells with wavy fibrillar cytoplasm, followed by myxoid change, perithelial pattern, hyaline change of the blood vessels, and hyalinlzed cords or nodules. Nine out of 12 cases of malignant schwannomas in group A and B, and 7 out of 9 cases of group C were positive for S-100 protein. None of the above cases showed positive staining reaction for keratin. Since 7 of 9 malignant schwannomas in Group C stained with S-100 protein, we can conclude that careful histological analysis supplemented by immunohistichemical study can make a conclusive diagnosis in most of the cases of malignant schwannomas even in cases that do not fulfil the traditional strict criteria.
