Spontaneously ruptured gastrointestinal stromal tumor (GIST) of the jejunum mimicking acute appendicitis

Gastrointestinal stromal tumors (GISTs) are characterized with diverse clinical presentations, including acute and chronic gastrointestinal bleeding, abdominal pain, presence of an intra- abdominal mass, anorexia, and intestinal obstruction. A 60-year-old obese woman presented as an acute abdominal emergency with right lower quadrant (RLQ) pain and tenderness, nausea and leukocytosis, all mimicking acute appendicitis. Laparotomy revealed a spontaneously ruptured GIST of the jejunum, which was localized to the RLQ due to postoperative adhesions following previous two cesarean sections and cholecystectomy. Complete surgical resection was performed, followed by an uneventful early postoperative course.
