The management of pineal region tumor remains controversial. This paper reports a case of pineocytoma which was attempted to improve treatment planning by the use of clinical features, computerized tomography, and markers for germ-cell tumor. A presumptive diagnosis could be made and this tumor less likely to respond to radiotherapy was subjected to primary surgery.

A 44-year-old female with cervical cord compression signs had myelographic and computerized tomographic evidence of extradural spinal cord compression without any tuberculous bony lesion or cold abscess. At surgery, cervical spinal cord was compressed by extraosseous extradural granulomatous tissue which was histologically proved a very rare localized extradural tuberculous granuloma.

The authors report a case of massive spontaneous intracerebral hematoma in a infant, caused by bleeding from cryptic vascular malformation associated with vitamin K dependant factor deficiency. The bleeding was initiated by vitamin K dependant factor deficiency, then 3 weeks later hematoma was expanded by rebleeding from malformed vessel after PT and PTT had been returned to normal values. The well circumscribed organized old hematoma with fresh expanded bleeding component within a huge rusty colored cystic fluid cavity was recognized in operative field and pathological ground.

During last 10 years we experienced 25 cases of C.N.S. cysticercosis. Now clinical analysis and evaluation of our cases were made and the results are followings; 1. Prevalence in man and women are nearly same and about 70% of cases are distributed between 20-50 years old. 2. According to Nieto's classification, mostly are ventricular (44%) and parenchymal type (36%). 3. Clinical manifestations were IICP (92%), focal neurological deficits (68%), seizure (48%), altered mental status (36%) and others listed on table 7. 4. In ventricular type, IICP and cerebellar dysfunction signs were predominated but seizure and focal neurological deficits were commonly seen in parenchymal type. 5. Subcutaneous cysticercus nodules were palpated in 32% of cases. 6. Positive stool ova was observed in 29% of cases. 7. Radiologic studies revealed as followings: 16% of cases showed abnormal findings on plain film, 84% on angiography, 94% on ventriculography and 100% on computed tomography and myelography. Computed tomography looks like most helpful diagnostic method for C.N.S. cysticercosis, they usually revealed lucent cystic lesion, hydrocephalic findings and contrast enhancement. 8. Suboccipital craniectomy, craniotomy with removal of parenchymal cyst or laminectomy were done according to location and types of lesion. 72% of operated cases revealed good results and mortality was 4% of cases.

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.

Histopathological diagnosis of brain stem glioma should be performed for the purpose of the determination of its management and clinical course, but its surgical biopsy has been followed by high mortality and morbidity. We performed the tissue sampling for histological examination with BRW stereotaxic system under local anesthesia successfully.

This study was designed to answer the question; (1) How does the DNA ploidy pattern change in hepatocarcinogenesis? (2) How does the nuclear morphology change in hepatocarcinogenesis? Diethylnitrosamine(DEN) (16.5 mg per kg) was subcutaneously injected to female Sprague-Dawley rats(150~200g) by weekly interval for 30 weeks. DNA ploidy and parameters of nuclear morphology were measured by image analyser(IBAS 200, Kontron, FRG). The DNA ploidy pattern was divided into three basic patterns(diploid, polyploid, and aneuploid modes). In 8 cases of saline-injected control rats, the DNA histograms showed all polyploid pattern. Inhepatocyte nodules(hyperplastic nodules), DNA diploidy was the most frequent pattern, being followed by polyploid and aneuploid DNA patterns, contrast to hepatocelular carcinomas in which polyploid DNA pattern was most frequently noted being followed by diploid and aneuploid DNA pattern. Although the nuclei of hepatocytes in hepatocyte nodules and hepatocellular carcinomas were larger and more pleomorphic than those of normal hepatocytes, they were as same as those of normal hepatocytes in regard to nuclear hyperchromasia. DNA content, which was increased in hepatocarcinogenesis, was significantly related to the nuclear area.

Atopic dermatitis is a common chronic inflammatory skin disease, associated with marked inflammatory cells (of mast cells and eosinophils) and severe itching, which leads to clinical problems in the pediatric population. This study was designed to investigate the inhibitory effects of luteolin liposome solution, that is entrapped the hydrophobic luteolin (one of the flavonoids) into ethosome to improve its stability, by using hapten-induced atopic dermatitis animal model (NC/Nga mice).The luteolin liposome treated mice showed anti-inflammatory effect as evidenced by the lowering of erythema and edema in clinical observation, reduction of inflammatory cell infiltration and epidermal thickness in histopathological examination, when compared with TNCB induced controls. Luteolin liposome solution also reduced the serum IgE level which played important roles in the atopic dermatitis model. These results suggest that luteolin liposome solution has some merit in this formulation showing inhibitory effects for the atopic dermatitis.
