A giant jejunal gastrointestinal stromal tumor misconceived as pancreatic cystic neoplasm: A case report.

Introduction: Gastrointestinal stromal tumors (GISTs), although not common in gastrointestinal (GI) tumors, constitute the most frequent mesenchymal tumors of the GI tract. This report describes a patient with a large sporadic GIST at proximal jejunum that mimicked the pancreatic cystic neoplasm.

Case Presentation: We report a 59-year-old female patient with unexplained weight loss and palpable left upper quadrant abdominal mass for 6 months.
