Germ cell tumors(GCT) are not infrequently encounted tumor in pediartic age group. In order to study the clinical behaviors of the disease, we reviewed 29 cases of GCT diagnosed and treated at Kosin Medical Center in the period of 7 years form Jan. 1984 to Dec. 1991 and the results are summarized as follows: 1) The age distribution is the highest between 10 and 15 years(45%) and girls have 1.9 times higher frequency than that of boys. 2) The most frequent primary site of GCT was ovary(15). The next common primary site was testis(5), pineal body(4), sacrococcygeal region(2), retroperitoneum(1), soft palate(1), anterior mediastinum(1) in descending order of frequency. 3) In the pathological analysis of tumors, the most frequent type was mature teratoma(12). The next common type was endodermal sinus tumor(6), immature teratoma(5), dysgerminoma(3), mixed type(2), and choriocarcinoma(1)in descending order of frequency. 4) All the 5 cases of EST have elevated serum levels of alpha-fetoprotein. Two of the three dysgerminoma, one of the two mixed type tumors both of which have germinoma components, and one choriocarcinoma have elevated serum levels of beta-HCG above the age related physiological levels. 5) Among 17 cases of malignant GCT, 9 cases have metastatic areas such as regional lymph nodes, scrotum, pleura, retroperitoneum, omentum and lumbar spine. 6) All except on case of immature teratoma in the anterior mediastinum underwent surgery. Chemotherapy was given to 12 of 17 malignant GCT and radiotherapy was given to 4 of 17 malignant GCT. 7) Among the 4 expired cases within 12 months of follow up, three were originated from pineal body, which had been underwent simple V-P shunt or incomplete resection, and one case was metastatic immature teratoma of anterior mediastinum to the pleura which had not been undergone surgery. Finally, in review of literature and or cases, the survival of properly managed GCT except some of those difficult surgical access is relatively good. To continue the survival of children of GCT to be impoved, we should use all the treatment modalit properly with more positive outlook about the disease.

Lymphomatous involvement of the heart, occurring at initial diagnosis and presentation, is extremely rare. We report here a case of 58 year old man who presented with generalized edema, pericardial effusion, and a large right atrial mass detected by transesophageal echocardiography. There is no other evidence of disseminated lymphoma in this patient. Tumor removal and pulmonary embolectomy was done. Pathologically, the mass was malignant lymphoma, diffuse large cell type. Unfortunately, we have no chance to perform the intensive chemotherapy. The patient discharged in moribund state.

Maintaining the blood supply of the interdental alveolar bone is crucial for preserving the interdental papilla. Rebuilding the interimplant papilla between adjacent implants is more difficult than rebuilding the interdental papilla between the natural tooth and implant. Therefore, preserving the interimplant tissue is necessary when adjacent implants are closely placed. In this case report, three effective methods for maintaining the surrounding tissue, namely strategic serial extraction, immediate implantation, and provisionalization of adjacent maxillary central incisors, were performed. The marginal gingiva and interimplant papilla were well maintained for 24 months.

Adenoid basal cell tumor of the prostate is a rare tumorous lesion that can be misdiagnosed as adenocarcinoma of the prostate. The malignant potential of adenoid basal cell tumor remains uncertain due to small number of reported cases. This 66-year-old man presented with symptoms of urinary tract obstruction. Under the impression of benign prostatic hyperplasia, a transurethral resection of the prostate (TURP) was performed. The patient was alive with no evidence of recurrence or metastasis 15 months after TURP. Microscopically, most of the lesions were composed of nodular collections of small nests of basaloid cells with peripheral palisading, and clusters of tumor cells forming cribriform pattern. Multiple areas of basal cell hyperplasia and atypical basal cell hyperpalsia were also observed. The coexistence of basal cell hyperplasia, atypical basal cell hyperpalsia, and adenoid basal cell tumor with cribriform pattern in this case supports a morphologic continuum from the benign hyperplastic lesion to malignant neoplasia.

The purpose of this study was to investigate whether the Bone Mineral Density (BMD) in a postmenopausal women has affected by a long-term swimming exercise. Swimming exercised 9 female and non-exercised 13 female were involved in this study. All of them were accepted by selection criteria through a questionnaire and personal interviews. Experimental group performed regularly swimming exercise while over a 8 year, but control group never taken part in any activities periodically. Bone densities were measured at Lumbar 2-4 and Femur's 3 sites (neck, ward's triangle, and trochanter) with DEXA method (Lunar DPX). There are no significant differences between two groups on the ages, body weights, heights, % fats, and menopausal durations. Bone densities on the neck and ward's triangle of Femur were 1.7% and 2.7% higher in the control group than in the swimming group, not significant between two groups. In the case of Femur trochanter and Lumbar 2-4 sites, swimming group however were nonsignificantly higher 2% and 5.3% than control group, respectively. In conclusion, it was recognized that a long-term swimming exercise may be ineffective to intensify local density, stiffly lowering in a postmenopausal women.

Recent investigations have revealed that autocrine growth factors and their receptors are closely related and play an important role in controlling cancer cell growth. We performed an immunohistochemical study on the expression of epidermal growth factor (EGF), transforming growth factor-alpha (TGF-alpha), epidermal growth factor receptor (EGF-R), c-erbB-2, and PCNA labelling index in 60 cases of human gastric carcinomas. TGF-alpha was detected in 38 cases (63.3%), EGF in 26 cases (43.3%), EGF-R in 44 cases (73.3%), and c-erbB-2 in 18 cases (30%). These growth factors, EGF-R and c-erbB-2, were found more often in advanced gastric cancers. The PCNA labeling index was significantly higher in tumors with the expression of EGF-R or c-erbB-2. Tumors with simultaneous expression of EGF, TGF-alpha, EGF-R and c-erbB-2 was associated with a high PCNA labeling index. A correlation was observed between the synchronous expression of growth factors and its receptors and histological differentiation. The results suggest that the expression of EGF, TGF-alpha, EGF-R and c-erbB-2 are closely related and plays an important role in the growth and progression of human gastric carcinoma.

In the present study, immunohistochemical detection of p53 oncoprotein was performed to determine whether the grade of differentiation and the histologic type of gastric adenocarcinoma, and the degree of atypia accompanied with adenoma can be related to p53 mutation. Paraffin sections of 22 gastric adenomas and 56 gastric adenocarcinomas were examined for the overexpression of p53 oncoprotein with the avidin-biotin peroxidase complex staining procedure. The obtained results were as follows; 1. All the 22 cases of adenomas and 16 cases of well differentated adenocarcinomas showed uniformly negative staining. 2.Seven of 18 cases of moderately differentiated adenocarcinomas(39%), and five of 30 cases of poorly differentiated adenocarcinomas(17%) exhibited p53 protein expression. 3. Three of 29 cases of diffuse type (10%) and 9 of 19 cases of intestinal type(47%) exhibited p53 protein expression. These results suggest that p53 mutation is important in carcinogenesis of the intestinal type of gastric adenocarcinoma, and there is no correlation between the differentiation of gastric adenocarcinoma and the degree of p53 oncoprotein overexpression.
