title: En bloc resection of the pancreatic head and second part of duodenum for a duodenal gastrointestinal stromal tumor: a multi-media report.
abstract: Duodenal gastrointestinal stromal tumors are rare tumors. When these tumors arise from the second part of the duodenum they can easily be misdiagnosed as a pancreatic head cancer. A case of a 37-year-old female presenting with a one-year history of right upper quadrant pain is described here, who was subsequently found to have a mass in the head of the pancreas. Computed tomography scans showed a 2 cm hypervascular lesion lying between the head of pancreas and the second part of the duodenum, suggestive of a neuroendocrine tumor, and confirmed by endoscopic ultrasound scan. She underwent a pancreatic head resection with duodenal segmentectomy. Histopathological and immunohistochemical analysis revealed the tumor to be peri-ampullary duodenal gastrointestinal stromal tumor not invading the pancreas. Duodenal gastrointestinal stromal tumor can have a wide spectrum of clinical presentation. The accurate diagnosis of duodenal gastrointestinal stromal tumor is essential for determining the appropriate surgical intervention. In our case, a conservative surgical approach was utilised therefore avoiding a formal pancreaticoduodenectomy.
