Abstract
- Gastric schwannoma is a very rare gastrointestinal mesenchymal tumor. Schwannoma in the gastrointestinal tract is usually not symptomatic, and preoperative abdominal CT or endoscopic evaluation cannot distinguish it from gastrointestinal stromal tumor. Surgical resection of this tumor is adequate to achieve a good prognosis. We performed laparoscopic gastric wedge resection in two patients who had the preoperative diagnosis of gastric gastrointestinal stromal tumor. In both cases, the postoperative immunohistochemistry staining was positive for S-100 protein and it was negative for CD34, which is consistent with gastric schwannoma. We report here on two cases of gastric schwannoma along with a review of the literatures.
