title: Spontaneous intraperitoneal hemorrhage as the initial presentation of a gastrointestinal stromal tumor: a case report.
abstract: BACKGROUND
  Spontaneous hemoperitoneum is rare. The most common etiologies are gynecologic, splenic, and hepatic. Gastrointestinal stromal tumors (GISTs) are commonly associated with intraluminal bleeding, but rarely with spontaneous hemoperitoneum. We report a case of spontaneous hemoperitoneum caused by a gastric GIST.
  
  
  METHODS
  A 54-year-old male presented with the acute onset of abdominal pain and a drop in hemoglobin. Subsequent evaluation, including a CT, MRI, and EUS, revealed a 1.2-cm mass along the greater curvature of the stomach and associated hemoperitoneum. The patient was taken electively to the operating room for laparoscopic removal of the mass. Pathology confirmed that it was a GIST.
  
  
  CONCLUSIONS
  GIST is a rare clinical entity that infrequently presents with spontaneous hemoperitoneum. Emergent treatment should be guided towards treating the spontaneous hemoperitoneum.
