Abstract
A case of neurilemmoma of the stomach is described. An abnormality of the stomach was detected in an asymptomatic 53-year-old female at a mass screening survey.
Upper GI series as minute examination revealed a submucosal tumor with a central ulceration of the gastric upper corpus measuring about 5×4 cm in diameter. The lesion was confirmed as group 1 by biopsy and we could not have a definitive diagnosis. We performed proximal gastrectomy with lymphnodes curettage because it was not completely ruled out that the lesion might be a malignant neoplasm. The resected specimen showed a submucosal tumor, 3.8×3.1 cm in size, at the anterior wall of the upper corpus. An ulceration was present at the top of the tumor.
Histopathological examination including hematoxylin-eosin staining (spindle shaped cells with a pattern of streaming in inconstant directions and lymphoid cuffs) and immunohistochemical staining (positive S-100 protein and negative desmin) led to the diagnosis of neurilemmoma.
Generally, it is very difficult to confirm a correct diagnosis of the submucosal tumor of the stomach preoperatively. It can not be said that the most appropriate surgical interventions have been adopted in accordance with malignant degrees of each case. We wish to emphasize that efforts must be made to accomplish a reliable and qualitative diagnostic method gaining an accurate histopathological diagnosis of the submucosal tumor of the stomach at the latest during operation. The efforts will lead to more satisfactory results in treating patients with submucosal tumor of the stomach.
