Hypersensitivity myocarditis is an inflammatory disease of the myocardium usually related to drug allergy. The clinical manifestation may be nonspecific, and the diagnosis is seldom suspected or established during the life. So in most of the reported patients, the diagnosis was made at autopsy. Although, retrospectively, more than 90% of the patients described have had clinically recognizable cardiac involvement before death, tole clinical suspicion of hypersensitivity myocarditis is rare. The presence of nonspecific cardiac finding in a patient receiving any drug associated with hypersensitivity should alert the clinician to the possibility of drug related myocarditis. We experienced a case of hypersensitivity myocarditis accompanying allergic skin lesion in a 58 years old man with a history of taking cefadroxil. Fortunately, the outcome was favorable, therefore we do not have histologic confirmation of the diagnosis.

Inflammatory pseudotumor of the urinary bladder is a proliferative spindle cell lesion that microscopically may suggest a sarcoma but that are benign without a recent history of an operation. The first such case was reported by Roth, in 1980, and thereafter about seven more cases were reported in medical literatures. We reported a case of inflammatory pseudotumor of the urinary bladder mimicking leiomyosarcoma. Patient was a 36-year-old woman with complaint of painless total and gross hematuria for 3 weeks. Partial cystectomy specimen showed a well-demarcated nodular mass of yellow white color, involving the submucosal and muscular layers. Microscopic examination revealed proliferating bundles of spindle cells interspersed with infiltration of many inflammatory cells including eosinophils. Spindle cells were positive for vimentin on immunohistochemistry and corresponding to myofibroblasts on the electron microscopic examination.

Strumal carcinoid of the ovary is a rare turkor characterized by an intimate mixture of thyroid follicles and carcinoid. Herein is reported an ovarian strumal carcinoid in a serous cystadenoma from a 27-year-old pregnant woman. The thyroid follicular epithelial cells had immunohistochemically thyroglobulin and carcinoid tumor cells contained neuron-specific enolase, chromogranin and carcinoembryonic antigen. In addition, carcinoid cells showed neuroendocrine granules ultrastructurally. Calcitonin and amyloid were not found. This tumor may be originated from pluripotent endodermal germ cells on the basis of morphologic, immunohistochemical and ultrastructural studies.

PURPOSE: This study investigated the effect of reducing cisplatin induced nephrotoxicity with DWP-04 that is the compound of Schizandrin C derivative biphenyldimethyl dicarboxylate (DDB), glutathione and selenium. For the purpose of observation is that how DWP-04 has influence on mechanism of reducing cisplatin induced nephrotoxicity with renal function test, free radical formation and detoxification enzyme system in renal tissue. METHODS: Five groups of rats were dosed with vehicle, cisplatin (2 mg/kg i.p.), cisplatin+DWP-04 (100, 200 mg/kg po), or cisplatin+sodium thiosulfate (200 mg/kg i.p.) daily for 4 weeks. RESULTS: Serum creatinine, lactate dehydrogenase and activity of hydroxy radical increased in the cisplatin group and suppressed in the cisplatin+DWP-04 group compared to the cisplatin group. The renal tissue concentration of lipid peroxidase and lipofuscin were increased in the cisplatin group compared to the other groups. The activity of aminopyrine N-demethylase, aniline hydroxylase, aldehyde oxidase and xanthine oxidase, of which free radical formation system in kidney was also decreased in the cisplatin+DWP-04 group compared to the cisplatin and cisplatin+sodium thiosulfate group. The activity of detoxification system of free radical, such as glutathione S-transferase, superoxide dismutase, catalase and glutathione peroxidase were markedly increased in the cisplatin+DWP-04 group than the cisplatin and the cisplatin+sodium thiosulfate group (p<0.05). CONCLUSION: It can be concluded that the mechanism of decreasing cisplatin-induced nephrotoxicity by DWP-04 is that the decreasing of the amount of lipid peroxide and lipofuscin in the renal tissue by increasing activity of the antioxidant defense system and the decreasing of reactive oxygen species by increasing detoxification enzyme activity.

We present a case of retroperitoneal teratoma in a 4-year-old girl in which a Wilms' tumor-like element was predominant, unlike the usual pattern of the immature or malignant teratoma. Mature elements were composed of adipose tissue, neural plexus and ganglia, cartilage, smooth and skeletal muscles, and glandular epithelium of the respiratory and gastrointestinal types. Three months after complete excision of the mass, a recurrent tumor developed. It consisted of only nephroblastomatous elements without teratomatous components. Theories for the histogenesis of this rare tumor are discussed.

Thirty cases of gastric adenocarcinoma were examined immunohistochemically for expression of transforming growth factor-beta(TGF-beta) in order to analyze significant correlation with clinical stage and pathologic grade of gastric adenocarcinoma. Specific immunostaining was clearly detected in the cytoplasm of the neoplastic cells. The TGF-,6 expression in the gastric adenocarcinoma is closely related to the depth of invasion, the degree of invasiveness and the presence of metastasis. Thus, we observed the stronger immunohistochemical. expression of TGF-beta in the deeper portion of invasion and in the invasive gastric adenocarcinomas with the lymph nodal metastasis than in the superficial portion of invasion and in those without the lymph nodal metastasis. There results suggest that the transforming growth factors expression in carcinoma cells may play an important role in the carcinomatous invasion resulting in metastasis.
