Gastrointestinal stromal tumor
Clinical manifestations include nonspecific symptoms such as early satiety and bloating. Often, GISTs are discovered on imaging performed for another purpose. GISTs may remain asymptomatic unless they ulcerate, bleed, or grow large enough to cause mechanical obstruction. Sites of metastases include the liver and peritoneum; lymph node metastases are not common.
