Brenner tumors constitute about l.5~2.5% of all primary ovarian neoplasms and are almost always benign. It appears to derive from the surface epithelium of the ovary which undergoes metap1asia to form the urothelial-like components. we experienced a case of malignant Brenner tumor with adenocarcinoma and squamous cell carcinoma patterns in a 57-year-old woman. It was partly cystic tumor and contained a 4cm-sized gray yellow, lobulated or papillary solid mass, projecting from the cystic wall. Ultrastructurally, the solid mass was composed of malignant urothelial-like cells with focal glandular differentiation.

We report a case of angiosarcoma of the jejunum in a 65-year-old female. This angiosarcoma developed 20 years after postoperative irradiation for cervical carcinoma of the uterus. Grossly, the resected jejunum showed a 8 cm long segmental hemorrhagic lesion with multiple, small hemorrhagic nodules or cysts on its serosa and mesentery. Microscopically, the wall of jejunum was infiltrated by epithelioid or polygonal tumor cells arranged in solid nests or lining irregular vascular spaces. The case is of interest that the tumor occurred in the very unusal site for angiosarcoma and the patient had a past history of irradiation for uterine cervical carcinoma 20 years ago. In addition, the resected intestine showed histologic changes of chronic irradiation effect. Therefore, this case supports the view that there is cause and effect relationship between irradiation adn angiosarcoma.

Ascariasis is probably the most common helminthic infestation of man, but it seldom causes severe illness. Pathologic conditions of Ascaris may be caused by adult worms, eggs or larvae. We describe a case of Ascaris egg granulomas that were found incidentally on the surface of the liver in a 75-year-old woman who had undergone a segmentectomy for an intrahepatic stone. Grossly, there were several yellowish calcific nodules of 0.4 cm in diameter on the lateral surface of the left lobe of the liver. Microscopically, the lesions were located in the hepatic capsule and consisted of fibrocalific nodules with many eggs. The eggs were round to oval, thick-shelled and measured 50~75x30~50 um. Most of the morphologically preserved eggs were fertilized eggs, but they had smooth shells without external protein coats. This case is of interest for the unusual location of the lesion, the presence of eggs without mammillation, and the association with the intrahepatic stone.

Although the reported number of malignant lymphoma of the thyroid has been increased, primary malignant lymphoma of the thyroid associated with chronic lymphocytic thyroiditis has been sporadically reported since its first description by Graham in 1931. The apparent coexistence of these two conditions has undoubtedly been noted by other observers. And they suggested that malignant lymphoma of the thyroid might arise from the lymphoid tissue ina wide variety of preexisting thyroidal disease. This report was made to record a case of primary thyroid lymphoma recently seen in this department with special emphasis on the associated thyroiditic changes in the uninvolved portion of the gland, which suggest the antecedent presence of chronic lymphocytic thyroiditis.

We report a case of giant cell tumor of the tendon sheath involving the foot, in a 21-year-old female patient, who presented with an asymptomatic tumor on the dorsum of her right foot. Histopathologically the tumor is surrounded by thin fibrous connective tissue. The characteristic findings of the excised specimen revealed a typical mixture of abundunt round or polygonal histocyte-like cells with varying portions of spindle-shaped fibroblast-like cells and multinucleated giant cells. Variable amounts of hyalinized fibrous stromal tissue were also present. After excision, local recurrence has not been observed for 3 months.

Core decompression is still widely used in avascular necrosis of the femoral head but the results are unpredictable and the indications are not settled yet. The reparative process of the decompressed femoral head is poorly understood. Seven cases in 5 patients were undertaken THRA following failed decompression and these were studied for the radiological and pathological changes of the core tracts. The lesions of failed cases were involved more than 1/3 of femoral head on MRI and all cases were stage II A or B. The extent of the necrotic area in MRI was enlarged with crack, sclerosis and sometimes gas collection. Depression of the subchondral plates were also observed. Capillary ingrowth or neovascularization was not found at all and there were only fibrosis, inflammatory response and foreign body reactions.

PURPOSE: To describe the lived experience of nursing students when faced with clinical judgment in a nursing practicum at the hospital. METHODS: A descriptive research design was utilized. Participants were 79 students in the clinical practicum. Participant consent was obtained for ethical protection. Data were collected from August to December 2007 using a semi-structured questionnaire. Content analysis was utilized for data analysis. RESULTS: Two categories and 5 themes were extracted from the data for 'difficult' and 'easy' clinical judgments. For the student category, the two themes were 'knowledge' and 'skill', while the three themes for the clinical education environment category were, 'judgment of clinical symptoms and signs', 'differences between theory and practice' and 'human relationships'. For coping, 2 categories and 5 themes were extracted for the difficult clinical judgment situation, while one category and one theme were found for the easy clinical judgment situation. CONCLUSION: To develop students' clinical judgment, there is need to develop the method of clinical skills using simulation in clinical teaching. For future research, a study on factors affecting clinical judgment of nursing students in hospitals is needed.

V.parahaemolyticus or V.alginolyticus infections are usually associated with consumption of raw or undercooked shellfish, contaminated food, and exposure of wounds to warm seawater. V.parahaemolyticus causes gastroenteritis(the most common syndrome), wound infections, and septicemia. V alginolyticus occasionally causes extraintestinal infections in humans. so far, the authors have not found the report of V.parahaemolyticus and V.alginolyticus isolation from a patient. So, we report a case of concurrent isolation of V.parahaemolyticus and V.alginolyticus from a patient who had a history of intestinal diarrhea and vomiting.
