Both mucinous cystadenoma of the appendix and intestinal schistosomiasis are rare lesions. We report a rare case of simultaneous giant mucinous cystadenoma of the appendix and intestinal schistosomiasis. A 64-year-old man from China presented with a one-year history of pain in the right lower quadrant of the abdomen. There were no other pertinent historical findings, other than schistosomiasis. Imaging showed a large, tubular, mesenteric cystic structure extending downwards from the inferior wall of the cecum. Right hemicolectomy was performed for the appendiceal tumor. The final pathological diagnosis was mucinous cystadenoma with calcified Schistosome eggs within the mucosa and submucosa of the appendix, small intestine, colon, and lymph nodes. We deduced that the pathogenesis of appendiceal mucinous cystadenoma in our case was Schistosome eggs causing luminal obstruction, finally resulting in intraluminal accumulation of mucoid material. Postoperatively, the patient recovered well.
阑尾黏液性囊腺瘤和肠道血吸虫病均为罕见病变。我们报告一例阑尾巨大黏液性囊腺瘤与肠道血吸虫病同时存在的罕见病例。一名来自中国的64岁男性，有右下腹部疼痛1年的病史。除血吸虫病外，无其他相关病史。影像学检查显示一个巨大的、管状的、肠系膜囊性结构，从盲肠下壁向下延伸。因阑尾肿瘤行右半结肠切除术。最终病理诊断为阑尾、小肠、结肠及淋巴结黏膜和黏膜下层有钙化血吸虫卵的黏液性囊腺瘤。我们推测本例阑尾黏液性囊腺瘤的发病机制是血吸虫卵导致管腔阻塞，最终导致腔内黏液物质积聚。术后患者恢复良好。
