A rare case of retroperitoneal ganglioneuroma incidentally found during an annual health examination is presented. The patient was an asymptomatic female, age 26. Physical examination and routine laboratory studies gave normal results. The plasma concentrations and 24-h urinary excretion of catecholamine and its metabolites were within the normal range. The patient was diagnosed as having a left supra-renal mass (6.3 X 3.6 cm) by abdominal ultrasono graphy, although by image diagnosis the paraadrenal mass could not be discriminated from an adrenal tumor. Operation was performed under the suspicion of a nonfunctioning adrenal tumor. The tumor removed was 8 X 6 X 4cm, 98g and was encapsulated. Histopathological diagnosis of retroperitoneal ganglioneuroma was confirmed. Forty-one cases of retroperitoneal ganglioneuroma in the Japanese literature including the present case are reviewed.

A case of a 6Q-year-old Japanese woman with small cell lung cancer involving skin and stomach is reported. She was diagnosed as primary small cell lung cancer accompanied by extensive cutaneous metastases. Three months after the last chemotherapy, she complained of nausea and vomiting. Brain CT scan showed no evidence of central nervous system involvement. Upper gastrointestinal study and upper gastrointestinal fiberscopy revealed multiple metastatic gastric tumors. Skin and stomach are uncommon metastatic sites for any malignancy. Furthermore, only a few cases with gastric metastasis could be diagnosed during their lifetime.
The combination of cisplatin and CPT-11 had definite activity against malignant pleural mesothelioma and was well tolerated. The intravenous administration of CPT-11 produced adequate distribution of CPT-11 and its active metabolite SN-38 into the pleural fluid and allowed a higher concentration of the more active SN-38 to make contact with mesothelioma cells in the thoracic cavity. These results warrant further clinical evaluation of this combination chemotherapy for the treatment of malignant pleural mesothelioma in a confirmatory Phase II trial.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
