title: Gastric adenocarcinoma and GIST (collision tumors) of the stomach presenting with perforation; first report.
abstract: Gastrointestinal stromal tumors are very rare tumors of stomach. To our knowledge there are a few reported cases of synchronous occurrence of epithelial and gastrointestinal stromal tumors of stomach. Also, tumor perforation is very rare. This is the first case of gastrointestinal stromal tumor synchronous with primary gastric adenocarcinoma presented with perforation (Fig. 1, Ref. 6).
