The carcinoma of uterine cervix is the most common malignant neoplasm in Korean women. Nearly all invasive cervical carcinomas are preceded by a intraepithelial stage. The cervical intraepithelial lesion(CIN) is subdivided into I, II, and III, depending on the severity of the changes. To evaluate the histologic characteristics of the CIN, we studied the CIN III by mapping of the uterine cervix. The results were as follows. 1. The CIN III without I or II was 54.8%(17/31 cases). 2. The multifocal CIN III was 12.9%(4/31 cases). 3. The horizontal growth of CIN III was 38.7%(12/31 cases). These results indicate that the CIN III is unifocal and CIN III without I or II is more common.

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.

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.

Evaluation of a fever of unknown origin (FUO) is complex. Recently, PET scanning has been approved for screening in FUO evaluation. We treated three cases of FUO associated with increased FDG uptake in the bone marrow of the femur and tibia on the fusion PET/CT; all three had the same pattern of uptake. Bone marrow biopsies revealed mature lymphocyte and histiocyte infiltration and myxoid changes in one case, and cortical bone involvement in another case. The cases were all young females who had fever with neutropenia and relative lymphocytosis that lasted for several weeks and then remitted spontaneously. Even though the results of the studies were not diagnostic, the unique uptake pattern on PET/CT and the histology might be related to the cause of the illness and should be studied further to assess the association with classic FUO.
