ABSTR 0917 – Proffered Oral Presentation: Pancreatic Extra-Gastrointestinal Stromal Tumor: An Unusual Presentation of a Rare Diagnosis

摘要

Background:Gastrointestinal stromal tumors (GISTs) rarely develop outside the digestive tract and such tumors are designated extra-GISTs (EGISTs). The majority of EGISTs are located in the mesentery, omentum, and retroperitoneum, and the primary localization in the pancreas has been reported in only about six cases. We describe a patient with a large metastatic pancreatic EGIST that had metastasized to the liver at time of presentation.
