Appendicular schwannoma is a rare tumor originating from Schwann's cells in the Auerbach plexus. The preoperative diagnosis is difficult because the clinical features are nonspecific, and it is mostly found accidentally via a radiologic image as a tumor, mimicking malignancy. We report a case of an appendicular schwannoma coexisting with an adenocarcinoma in the lung. A laparoscopic appendectomy was done with a clear resection margin, and the immunohistochemical staining showed positive S-100 protein, which confirmed the schwannoma. The patient also underwent a left upper lobectomy of the lung. The patient has been free of recurrence for the 6 months since the operation. The laparoscopic approach could be available for treatment of an appendicular schwannoma, thus avoiding an unnecessary laparotomy.
阑尾神经鞘瘤是一种罕见的肿瘤，起源于奥尔巴赫神经丛的施万细胞。术前诊断困难，因为其临床特征不具有特异性，大多是在影像学检查时偶然发现为肿瘤，类似恶性肿瘤。我们报告一例阑尾神经鞘瘤与肺腺癌并存的病例。行腹腔镜阑尾切除术，切缘清晰，免疫组化染色显示S-100蛋白阳性，确诊为神经鞘瘤。患者还接受了左肺上叶切除术。术后6个月患者无复发。腹腔镜手术可用于治疗阑尾神经鞘瘤，从而避免不必要的开腹手术。
