Synchronous adenocarcinoma and gastrointestinal stromal tumors of the stomach treated laparoscopically.

Gastric adenocarcinomas account for approximately 95% of primary gastric tumors, and gastrointestinal stromal tumor (GIST) is the most common gastrointestinal mesenchymal tumor, accounting for 1%-3% of primary gastric tumors. However, the synchronous occurrence of GIST and gastric epithelial tumor is rare. We herein report a case of synchronous occurrence of gastric adenocarcinoma and two GISTs of the stomach. All lesions were resected laparoscopically. We discuss this case and review the literature.
