胃神经鞘瘤较少见，仅占胃良性肿瘤的１０％左右。我院近１０年发现７例。本病多发生于中老年人，发展缓慢，病程可达２０余年。其临床表现与合并症有关，肿瘤多位于胃底、胃体部的粘膜下，肉眼与其它良性肿瘤无法鉴别，合并大溃疡者易误为胃癌。肿瘤切面呈灰红色或灰白色，镜下瘤细胞呈旋涡状、栅栏状或编织状排列。若胃有巨大肿瘤，而临床上无明显转移征象，应想到胃神经鞘肿瘤，本病预后良好，即便恶变也不转移到区域淋巴结，手术疗效较好。
Gastric schwannomas are rare, accounting for only about 10% of benign gastric tumors. In our hospital, 7 cases have been found in the past 10 years. The disease occurs mostly in the middle-aged and elderly people, and its development is slow. The disease course can reach more than 20 years. The clinical manifestations are related to complications. The tumors are located in the submucosal area of the stomach and stomach body. The naked eye and other benign tumors can not be identified. The merger of large ulcers is easy to mistaken for gastric cancer. The tumor surface is grayish red or grayish white, and the tumor cells are vortex-like, palisade-like, or braided. If there is a large tumor in the stomach and there are no clinically significant signs of metastasis, a gastric nerve sheath tumor should be considered. The prognosis of this disease is good. Even if the malignant transformation does not metastasize to the regional lymph nodes, the curative effect is better.
