An unusual case of pancreatic and gastric neoplasms (2010: 12b). Malignant GISTs originating from the pancreas and stomach.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the digestive tract and are believed to originate from the neoplastic transformation of the interstitial cells of Cajal from their precursors. GIST can occur anywhere but mainly affects the stomach (60%), jejunum and ileum (30%), duodenum (4-5%), rectum (4%), colon, appendix and esophagus. Primary GISTs of the pancreas are very rare, with only five previous cases reported. This is an unusual case of multiple GISTs in the pancreas and stomach.
