 A case of gastrointestinal tumor (GIST) neural type of stomach in a 41-year-old woman, detected by gastric endoscopy during a complete physical checkup was reported. X-ray examinations revealed a hemispheric submucosal tumor with central large ulcers, the surface of which was smooth and covered with gastric mucosa, in the greater curvature of the gastric angulus. Gastrectomy was performed. In the histological findings of the resected specimen, this tumor was showen to be composed of spindle cells, partly showing whorled or palisaded growth pattern. Immunohistochemically, tumor cells showed positive staining for S-100 protein and neuron-specific enolase (weakly), but were negative for α-smooth muscle actine. From ultrastructual evidence we conducted that it was a case of GIST, neural type.
