Although it can affect any part of the gastrointestinal system, signet ring cell carcinoma (SRC) is a common malignant entity stomach cancers. We discuss case patient who had prior history gastric adenocarcinoma with cells, for which he underwent partial gastrectomy gastro-jejunal anastomosis. Four months after surgery, presented an acute postoperative blockage. Operative findings and pathology...

The eastern oyster (Crassostrea virginica) developed neoplastic disorders when experimentally exposed both in the laboratory and field to chemically contaminated sediment from Black Rock Harbor (BRH), Bridgeport, Connecticut. Neoplasia was observed in oysters after 30 and 60 days of continuous exposure in a laboratory flow-through system to a 20 mg/L suspension of BRH sediment plus postexposure...

Introduction: Gastrointestinal stromal tumors (GISTs) are rare neoplasms of the gastrointestinal tract associated withhigh rates malignant transformation. Most GISTs present asymptomatically. They best identified by computedtomography (CT) scan and most stain positive for CD 117 (C-Kit), CD34, and/ or DOG-1. There have been many riskstratification classifications systems which calculated based ...

The frequency of detection stromal gastrointestinal tumors in children and adolescents is about 0.4% the total number diagnosed GISTs. These can occur throughout tract. During instrumental research, misinterpretation tumor origin possible. For this reason, consistent use a variety non-invasive diagnostic methods extremely important preoperative period. We present case report rare GIST pediatric...

They may rarely arise in the urinary bladder, where this can be eventually miscued as any other commoner bladder neoplasms. The current study was conducted to connote an uncommon clinicopathological presentation by a carcinoid tu...
