Pancreatic extragastrointestinal stromal tumor invading the duodenum

Abstract

Extragastrointestinal stromal tumors that arise in the pancreas are extremely rare and managing them can be difficult, particularly if located in the head of pancreas. This case report aims to contribute to the existing data in the literature regarding extragastrointestinal stromal tumors with rare and unusual locations. We present a 56-year-old man who presented with recurrentmild right upper quadrant abdominal pain. Abdominal computed tomography and magnetic resonance imaging revealed amass lesion with a diameter of 10 cm localized in the head of pancreas. Pancreaticoduodenectomy with complete tumor excision was performed. He was discharged on the postoperative day 14. Only 15 extragastrointestinal stromal tumors cases havebeen reported. Of these 15 cases, tumors were located in the head of pancreas in six cases. Here we report the seventh caseof pancreatic extragastrointestinal stromal tumor arising in the head of pancreas and also the largest of these seven tumors.
