We report herein the case of a 71-year-old-Japanese woman who was admitted to hospital for surgical treatment of a lower abdominal tumor. At laparotomy the tumor was found to be pedunculated and growing extramurally from the greater curvature of the stomach. Thus, a wedge resection of the stomach, including the mass, was performed. The tumor measured about 9 x 8 x 7 cm and histological examination of the resected specimen showed that the main elements consisted of wavy, long-spindled cells, which crossed irregularly, indicating that it was palisading negative. Immunohistochemically, the specimen was positive for both S-100 protein and Alcian blue. From these findings, the tumor was histologically diagnosed as a neurofibroma. The patient had an uneventful postoperative course and no signs of recurrence have been recognized in the 3 years since her operation.
我们在此报告一例71岁的日本女性病例，该患者因下腹部肿瘤入院接受手术治疗。剖腹手术时发现肿瘤有蒂，从胃大弯处向壁外生长。因此，对包括肿块在内的胃进行了楔形切除术。肿瘤大小约为9×8×7cm，对切除标本进行组织学检查显示，主要成分是波浪状的长梭形细胞，这些细胞不规则交叉，提示栅栏状排列阴性。免疫组织化学检查显示，标本的S-100蛋白和阿尔辛蓝均呈阳性。根据这些发现，该肿瘤在组织学上被诊断为神经纤维瘤。患者术后恢复顺利，术后3年未发现复发迹象。
