title: [Gastric schwannoma].
abstract: A rare case of gastric schwannoma is reported. A 36-year-old woman whose endoscopy showed a mucosa tumor, biopsy findings were suggestive for leiomyoma. Diagnosis was made only with postoperative histology that revealed the benign schwannoma. Immunohistochemical staining showed positivity for S-100 protein and the neuron specific enolase, schwannoma is often associated with Von Recklinghausen's disease. Surgical resection is recommended as their malignant potentiality. Gastric and small intestine localizations are often with bleeding. They also represent almost the 24% of all gastrointestinal stromal tumors (GIST) and the 4% of all primary retroperitoneal tumors.
