Primary leiomyosarcoma of the stomach is rare, representing 1% of all malignant gastric tumours. Little is known about its symptomatology, and ultrasound endoscopy with a biopsy is the most effective way of making a diagnosis. Full surgical resection is the most common treatment for gastric leiomyosarcoma.We are reporting on a rare case of a massive leiomyosarcoma of the stomach, in a patient aged 40 years with no specific symptomatology, and in whom the diagnosis was made following an exploratory laparotomy. The patient was treated with a partial gastrectomy, extended to the spleen. 相似文献

Ureaplasma urealyticum comprises 14 serotypes. The existing serotyping methods all use polyclonal antibodies. These methods are time-consuming and labor-intensive, and they cannot always be performed on primary isolates; in addition, the results are difficult to interpret. We developed a new enzyme-linked immunosorbent assay (ELISA) method using serotype-specific monoclonal antibodies (MAbs) to enable the serotyping of U. urealyticum isolates from primary broth cultures. Each of the 14 serotype reference strains was tested against 14 selected MAbs. Homologous reactions were very strong, while heterologous reactions were negligible. Three cross-reactions were observed: MAb 5 cross-reacted with serotype 2, MAb 14 cross-reacted with serotype 3, and MAb 8 cross-reacted with serotype 13. Despite the cross-reactions observed, all the serotype reference strains of U. urealyticum could be identified and differentiated using a combination of MAbs. Reproducibility was analyzed with a fractionated antigenic preparation and with several freshly prepared antigens of the same strain. No significant interrun variation was found with the fractionated antigen, but significant variations in optical density (OD) values were found when freshly prepared antigens were tested. However, the variation in OD values did not influence the overall interpretation of the ELISA: reactions with homologous MAbs were always prominent compared to those of the negative controls. This newly developed ELISA using MAbs seems promising for serotyping of U. urealyticum clinical isolates. 相似文献

Behçet’s disease (BD) is a vasculitis characterized by oral and genital ulcers and uveitis. Involvement of the digestive tract is called entero-Behçet’s disease. The most frequent sites of gastrointestinal involvement are the colon and the ileocecal region. Gastric involvement is rarely seen. We report the case of a 45-year-old man with a history of Behçet’s disease, in whom an upper gastrointestinal endoscopy performed because of gastric pain revealed a large gastric ulcer which was diagnosed as related to Behçet’s disease. 相似文献

The authors report a case of giant retroperitoneal liposarcoma revealed by an abdominal mass and non specific digestive symptomatology. They discuss, through a review of the literature, the different clinical, radiological, anatomopathological, therapeutic and evolutive aspects of abdominal liposarcoma. 相似文献

Intraductal papillary mucinous neoplasms of pancreas (IPMN) are cystic lesions of the pancreas than can be associated with extra-pancreatics malignancies. We report a case of intraductal papillary mucinous neoplasm discovered incidentally during the staging of rectal adenocarcinoma. This observation illustrates the high frequency of IPMN incidentally discovered, for instance during the work-up of an extrapancreatic tumor. 相似文献
