Abstract：
Gastric schwannomas (GS) are rare mesenchymal tumors from Schwann cells in the gastrointestinal (GI) tract, representing 2-6% of such tumors. We report a 52-year-old woman who experienced abdominal pain, hematemesis, and melena, initially suspected of having a GI stromal tumor through ultrasound and computed tomography abdomen. Despite no active bleeding found during an upper endoscopy, she underwent a successful open subtotal gastrectomy, with histopathology confirming GS. The diagnosis of GS, which may mimic other GI conditions, relies heavily on imaging and histopathological analysis due to its nonspecific symptomatology, including the potential for both upper and lower GI bleeding. This case underscores the diagnostic challenges of GS and highlights surgical resection as the preferred treatment, generally leading to a favorable prognosis.
摘要：
胃神经鞘瘤（GS）是胃肠道（GI）中来自雪旺氏细胞的罕见间质肿瘤，占此类肿瘤的2-6%。我们报道了一名52岁的女性，她经历了腹痛，呕血,还有Melena,最初通过超声和计算机断层扫描腹部怀疑患有胃肠道间质瘤。尽管在上内窥镜检查期间没有发现活动性出血，她接受了一次成功的开腹胃大部切除术,组织病理学证实GS.GS的诊断，可以模仿其他胃肠道条件，由于其非特异性症状在很大程度上依赖于影像学和组织病理学分析，包括上消化道和下消化道出血的可能性。该病例强调了GS的诊断挑战，并强调了手术切除是首选治疗方法。通常导致良好的预后。
