The clear cell variant of ependymoma is a rare, recently described, intracranial tumor which is composed of clear neoplastic ependymal cells. Clear cell ependymomas may share characteristic histologic features of oligodendrogliomas or central neurocytomas; striking nuclear uniformity, perinuclear halos, and numerous angulated capillaries. In contrast to oligodendrogliomas, however, clear cell ependymomas are noninfiltrating tumors with sharp boundaries. Perivascular pseudorosette formation is frequent. Oligodendrogliomas are usually nonreactive for GFAP compared to diffuse immunoreactivity of clear cell ependymoma. Central neurocytomas may also be differentiated by their immunoreactivity for synaptophysin. This is a case of clear cell ependymoma in a 40-year-old man. By computed tomography and magnetic resonance imaging scans, a well circumscribed cystic tumor with mural nodule was demonstrated in the right frontal lobe. It was 6cm in diameter and well enhanced. Histologically, it was sharply demarcated from the brain parenchyma. The cystic wall was lined by atypical ependymal cells, which "transformed" to clear cells in the solid area. The cells had uniform nuclei and perinuclear halos. Mitotic figures and necrotic foci were focally present. The cells were immunoreactive for glial fibrillary acidic protein (GFAP), while synaptophysin was negative. Electron microscopy revealed densely packed polyheadral cells with scant organelles and well developed intercellular junctions.

We treated three cases of bone tumors-giant cell tumor, chondroblastoma and malignant fibrous histiocytoma-with a custom-made prosthetic replacement. The patients were followed from 10 months to 18 months, postoperatively. The results of these study are as follows: 1. Satisfactory anatomic restoration 2. Early ambulation 3. Good function 4. Biomechanically sound reconstruction

One hundred eighty-six cases of ovarian common "epithelial" tumor including 28 endometriosis were reviewed, from the pathology file of the department of pathology of the National Medical Center during a period of 8 years and 6 months from January 1976 to June 1984. The study consisted of 14 cases(77.4%) of benign tumor including 28 cases of ovarian endometriosis, and 21 cases(11.3%) of borderline malignancy and 21 cases(11.3%) of invasive malignant tumors. Among benign common "epithelial" tumors, mucinous cystadenoma(69 cases) was the most frequent tumor, followed by serous cystadenoma (42 cases) and Brenner tumor (5 cases). Of borderline tumor, borderline mucinous tumor (18 cases) was more frequent than serous tumor (3 cases). Serous cystadenocarcinoma(9 cases) was the most frequent malignant tumor, followed by mucinous cystadenocarcinoma(6 cases), endometrioid carcinoma(3 cases) and undifferentiated carcinoma(3 cases). Most ovarian common "epithelial" tumors were prevalent during the reproductive age, but malignant tumors were more prevalent after the age of 40. Although right side was more frequently found (85 vs. 67) there is no significant site predilection. Bilaterality was the most common in undifferentiated carcinoma(66.7%), followed by serous cystadenocarcinoma(44.4%) and Brenner tumor(40%). The size of tumor tended to be larger in malignant tumor than benign. Mucinous tumor were usually larger than serous tumor. There were 7 intrauterine and 1 ectopic tubal prognancy which were associated with ovarian common "epithelial" tumors. Three cases of tumors were excised during Cesarian section. In summary these findings are comparable to other reports in Korea and English literatures. Histologic analysis of borderline and malignant epithelial tumor was done to emphasize their biologic behavor. Further study is required to compare their histological grading and clinical staging with thier survival rate.

The adequate treatment of tibia fracture is one of the most difficult due to severe commiuntion, open wound, delayed union, angulation deformity and infection. We treated 38 fractures of the tibia by Interlocking intramedullary nail from Feb. 1983 to Mar. 1993. 35 cases of the tibia fracture were fresh, 13 cases of fracture were open. The other 3 cases were delayed union and nonunion. The Mean follow-up was 14.0 months. The results were as followings. 1. Of the 38 fractures, 37 fractures united and the mean union time was 18.7 weeks. 2. Interlocking intramedullary nail could be used to the majority of fractures of the proximal & distal tibia shaft. fractures. 3. The Im erlocking nail had rigid rotational stability and was appropriate for the treatment in severe unstable fractures, commninution and open-with bone loss. 4. Delayed union or nonunion was a good indication for intramedullary nailling. 5. The major-complication were valgus deformity of 2 cases, varus deformity of 1 case, 1 case deep infection. 6. Interlocking intramedullary nailing provided rigid fixation of . fracture and then made early joint motion exercise and ambulation.
