The 5 year-survival rates were examined to evaluate the prognositic significance of the expression of the p53 protein and the positivity of the PCNA in 108 cases of advanced gastric carcinoma. The p53 protein and PCNA were stained by immunohistochemistry in the tissue of the gastrectomized specimen. The results were as follows. 1) The overall 5 year-survival rate of advanced gastric carcinoma was 42.3 % and the significant prognostic factors were a pathologic stage and p53 protein(p<0.005). 2) The expanding or infiltrating type by Ming's classification and the intestinal or difftise type by Lauren's classification had similar prognosis. 514_ @@l %R-t 3) The 5 year-survival rate of the p53-positive group was 25.1% and that of p53-negative group was 56.1%(p<0.005). 4) The 5 year-survival rate of the PCNA low-grade tumors by PCNA stain(<50%)was 48.7% and that of the high-grade tumor(>=50%)was 29.9%(p>0.1). 5) There was a tendency to have a good prognosis in the p53-negative group and low grade tumors in the stage 11, III, and IV. There was a significant difference between p53 protein positive and negative groups in the stage III(p<0.005), but no significant differences were found in the other groups. The above results indicate that the p53 protein is an another useful tool for prediction of the prognosis in advanced gastric carcinoma.

This study aimed to differentiate gastric mucosal lesions such as the inflammatory gastric mucosa, gastric dysplasia and adenocarcinoma, using the CEA(carcinoembryonic antigen), AgNORS(Nucleolar organizer regions) and PCNA(proliferating cell nuclear antigen) stains. The tissue samples were taken from 30 cases of inflammatory gastric mucosa (19 gastritis and 11 regenerative hyperplasia), 28 cases of gastric dysplasia (9 mild dysplasia, 10 moderate dysplasia and 9 severe dysplasia) and 21 cases of gastric adenocarcinoma. The CEA was expressed in 16 of 21 adenocarcinomas(76%), but in neither inflammatory nor dysplastic gastric mucosae. The mean number of AgNORs per nucleus was 1.54 in inflammatory gastric mucosa, 1.80 in gastric dysplasia, and 1.88 in adenocarcinoma. The number of AgNORs was increased in dysplasia and adenocarcinoma compared to the inflammatory gastric mucosa without statistical significance. The percentage of the PCN A positive cells was 35.2% in inflammatory gastric mucosa, 44.1 % in gastric dysplasia, and 69.0% in gastric adenocarcinoma. The positivity of the PCNA was significantly increased in adenocarcinoma compared to the inflammatory gastric mucosa and dysplasia. In conclusion, the frequency of the CEA positive staining was increased in the gastric adenocarcinoma, and so CEA stain will be able to provide an additive method for the differential diagnosis between severe dysplasia and adenocarcinoma of the stomach.

A case of carcinoma of the parathyroid gland causing hyperparathyroidism was experienced at the department of orthopaedic surgery, C.A.F.G.H. This patient, a 23 years old male, had complained of a left shoulder pain during the past 3months. And weakness of the lower extremities causing walking disturbance, multiple bone pain, and polyuria had occurred sinoe one month before admission. Physical examination revealed a hard palpable mass in the right anterior region of the neck. Radiologic examination revealed subperiosteal bone resorption in phalanges of the hands and feet, generalized osteoporosis and cystic lesions, and pathologic fracture of the ribs, left humerus, and left femur. Laboratory studies demonstrated hypercalcemia, hypophosphatemia, increased alkaline phosphatase and PTH, hypercalciuria, and hyperphophaturia. Sonogram and C-T scan of the neck revealed a mass in the right inferior portion of the thyroid. Rib biopsy revealed the findings of ostitis fibrosa cystica, and parathyroid gland and regional lymph node biopsy revealed a parathyroid carcinoma with regional lymph node metastasis.

Multilocular cystic renal cell carcinoma appears to be a distinct and rare subtype of renal cell carcinoma with characteristic gross and microscopic features. Multilocular cystic renal cell carcinoma should be separated from multilocular cyst, multilocular cystic nephroma, and renal cell carcinoma with cystic degeneration. We present a case of multilocular cystic renal cell carcinoma. A 61-year-old man presented with right flank pain for 4 years. The computerized tomography revealed multilocular cystic mass in the upper pole of right kidney. The cystic mass measured 4.5x4 cm. The cyst was multilocular and locules not communicated with each other. The solid area was not present. Microscopically, the locules were lined by flat or cuboidal neoplastic clear cells. The clear cells were focally aggregated in the septa. The nephron was not present in the septa.

It is important to predict the prognosis of patient with cancer. Well known parameters predicting the prognosis are staged and degree of differentiation. Recently, the prognostic and diagnostic significance of silver-stained nucleolar organizer regions(Ag-NORs) and flow cytometric DNA analysis are introduced. This study aims to detect the diagnostic significance of Ag-NORs in breast lesions, and to correlate the number of Ag-NORs and cellular ploidies in breast carcinoma. In addition, the existence of heterogeneity according to the sample in the same patient is studied Sixty six paraffin blocks(two primary lesions and the two metastatic lymph nodes in 13 patients, and one primary lesion and one metastatic lymph node I 10 patients) of breast carcinoma, 30 paraffin blocks of fibroadenoma and 23 paraffin blocks of normal breast are studied. The numbe of Ag-NORs increase from normal breast(mean 1.45) through fibroadenoma(mean 1.60) to carcinoma(mean 2.43). It was significantly different between each lsions(P<0.0005). The number of Ag-NORs increased in the aneuploidy carcinoma than that in the euploidy one(P<0.05). But, there was difference between the number of Ag-NORs and DNA index according to the sample area in the same patient with carcinoma. In conclusion, the number of Ag-NORs is diagnostically significant in breast lesions and is correlated with cellular ploidies in breast carcinoma. In addition, Ag-NORs and cellular ploidies are heterogenous in the same patient.
Neoplasm Metastasis

Epstein-Barr virus (EBV) has been known to be associated with a wide variety of neoplastic conditions including nasopharyngeal carcinoma, Hodgkin's disease, and non-Hodgkin's lymphoma. Recent studies reveal the presence of EBV in certain subtypes of gastric carcinoma in which EBV appears to be pathogenetically related. To evaluate the relationship between EBV and gastric adenocarcinoma, we examined EBV DNA using direct in situ polymerase chain reaction, and expression of p53 protein and bcl-2 protein using immunohistochemical staining method on paraffin embedded tissues. The materials consisted of one hundred twenty-eight gastric adenocarcinomas and twenty benign peptic ulcers. EBV DNA was detected in 14 of 128 gastric adenocarcinomas (10.9%). p53 protein was positive in 10 of 14 EBV positive adenocarcinomas (71.4%) and in 61 of 114 EBV negative adenocarcinomas (53.5%). Bcl-2 protein was positive in 2 of 14 EBV positive adenocarcinomas (14.3%) and in 19 of 114 EBV negative adenocarcinomas (16.7%). The above results indicate that EBV is associated with gastric adenocarcinoma, and p53 protein may play a role in carcinogenesis of EBV in gastric adenocarcinoma.

Maligant melanomas of the oral or nasal cavity, and the vulvovaginal area are relatively common among the melanomas of non-ocular mucosa. But, primary malignant melanoma arising in the mucosa of the palatine tonsil is rare. We present a case of primary malignant melanoma arising in the mucosa of the palatine tonsil. A 36-year-old male was admitted for evaluation of a recurrent sore throat. Tonsillectomy was performed on the basis of clinical suspicion of chronic tonsillitis. Grossly, the left tonsil was focally dark. Microscopically, the tonsillar mucosa was diffusely infiltrated with tumor cells. Tumor cells revealed numerous melanin pigments. Intraepithelial nests of tumor cells were noted, but pagetoid spread of tumor cells was not found. Tumor cells were positive for S-100 protein and HMB45 stain. There was no evidence of melanoma in the skin or eye.

Osteoblastomas were originally thought to be lesions that could be controlled with minimal local therapy, including curettage. However, at least some of the osteoblastomas with an unexpectedly active clinical course had histologic features which differed from ordinary osteoblastomas, and the term aggressive osteoblastoma was given to these lesions. In the aggressive osteoblastoma the osteoblasts are cytologically atypical. In addition, the well organized trabecular patterns of typical osteoblastoma is partly lacking, especially in the areas that are rich in atypical osteoblasts. The case report deals a case of aggressive osteoblastoma of the left iliac wing in a 44 year old male. The interesting radiologic manifestationa(plain x-ray CAT and radionuclide bone scan) and characteristic histologic findings are presented along with review of pertinent literatures.
