They are often incidental findings at endoscopy—especially in Japan due to mass screening for gastric cancer—or at surgery for other causes
Epidemiology More common in the middle-aged to elderly
DiffDx Leiomyoma, schwannoma, sarcoma, adenocarcionoma, ectopic pancreas
Management Most GISTs respond well to the tyrosine-kinase inhibitor imatinib mesylate (Gleevec/STI-571)
