Appendicular schwannomas are very rare condition with nonspecific clinical symptoms and frequently recognized during pathological examination. They arise less frequently in the gastrointestinal tract and comprise ~1% of all malignant gastrointestinal tumours. We presented a rare case of an appendicular schwannoma that was discovered incidentally in a 25-year-old student diagnosed with appendicular mucocoele with a suspected obstructing tumoural lesion based on computed tomography findings. A colonoscopy examination showed a bulging, nodular, erythematous lesion at the base of the caecum (appendiceal orifice). Biopsies showed mixed inflammatory infiltration in the lamina propria, with lymphoid-filled formations. No evidence of dysplasia or neoplasia. Tumour markers were negative. Appendicular neoplasms, such as schwannomas of the appendix, are rarely associated with nonspecific clinical symptoms and are frequently recognized during pathological examination of the resected appendix. Laparoscopic surgery with a clear resection margin is the cornerstone of treatment for appendicular schwannoma, and it is associated with a favourable prognosis.
阑尾神经鞘瘤是一种非常罕见的疾病，临床症状不具特异性，常在病理检查时才得以确诊。它在胃肠道的发生率较低，约占所有胃肠道恶性肿瘤的1%。我们报告了一例罕见的阑尾神经鞘瘤病例，该病例是在一名25岁的学生身上偶然发现的，该学生被诊断为阑尾黏液囊肿，根据计算机断层扫描结果怀疑存在阻塞性肿瘤病变。结肠镜检查显示在盲肠底部（阑尾开口处）有一个隆起、结节状、红斑样病变。活检显示固有层有混合性炎症浸润，伴有充满淋巴细胞的结构。未发现发育异常或肿瘤形成的证据。肿瘤标志物呈阴性。阑尾肿瘤，如阑尾神经鞘瘤，很少伴有非特异性临床症状，常在切除阑尾的病理检查时被发现。具有清晰切缘的腹腔镜手术是阑尾神经鞘瘤治疗的基石，且预后良好。
