Core Tip
Core tip: Gastrointestinal stromal tumors (GISTs) tend to arise with a higher frequency in the stomach and the small bowel. In fewer than 5% of cases, they originate primarily from EGISTs. Among them, pancreatic GIST is very rare, with only 14 previous cases reported. Here, we report two cases of malignant pancreatic GIST and review the cases previously reported in the literature.
