Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal (GI) tract. These tumors are frequently small, asymptomatic and found incidentally. GI bleeding is a common complication of these tumors, but small sized, very low risk GIST rarely complicated with fatal bleeding. In this report, we describe a 42-year-old woman with a jejunal GIST accompanied by severe GI bleeding. She presented with melena and an angiographic embolization was performed for a jejunal mass with bleeding. However, rebleeding was suspected after an angiographic embolization and an emergent segmental resection for the bleeding mass was performed. She was finally diagnosed as a 1.8 cm sized very low risk GIST in jejunum. In conclusion, physician should consider that even very low risk GIST can be the cause of GI bleeding when there is severe bleeding.

Surgery is the primary treatment for adenocarcinoma originating from the esophagogastric junction. However, many physicians attempt various endoscopic treatments for the cases of early adenocarcinoma and high-grade dysplasia of esophagogastric junction in order to avoid the high risk of complications associated with surgical resection. Recently, there is an increasing tendency to use endoscopic mucosal resection for the management of early esophageal cancer due to low morbidity and mortality rates. We report here on a case of early adenocarcinoma at esophagogastric junction successfully treated with endoscopic mucosal resection.
