title: [A case report of gastrointestinal stromal tumor of the small intestine presenting with liver abscesses caused by Streptococcus constellatus].
abstract: A 49-year-old woman visited a local hospital in October 2007 with complaint of fever and melena. Abdominal ultrasonography and abdominal computed tomography revealed an irregular mass in the lower abdomen, together with multiple masses in the liver. She was admitted because of anemia, and the high fever was determined to be an inflammatory response. Blood tests revealed elevated biliary enzyme levels. Percutaneous biopsy of the liver mass was performed, which revealed liver abscesses caused by Streptococcus constellatus. On abdominal angiography, the mass was suspected to be a tumor of the small intestine. In late November 2007, laparoscopy-assisted partial small bowel resection was performed, and pathological examination of the surgical specimen confirmed gastrointestinal stromal tumor (GIST) of the small bowel. Because reports of small intestinal GIST with liver abscesses caused by Streptococcus constellatus are rare, this case description could provide valuable information.
