Appendiceal neoplasms (ANs) are rare and often mimic acute appendicitis, complicating timely diagnosis. We report a unique case of a 57-year-old male presenting with right lower quadrant pain, found on imaging to have a ruptured appendiceal mucocele. He underwent open right hemicolectomy, and histopathology revealed concurrent moderately differentiated mucinous adenocarcinoma arising within a high-grade appendiceal mucinous neoplasm-the first such case documented in the literature. This case underscores the need for early detection, proper surgery, and long-term follow-up in managing rare concurrent appendiceal tumors.
阑尾肿瘤（ANs）较为罕见，常表现类似急性阑尾炎，致使及时诊断复杂化。我们报告了一例独特病例，一名57岁男性因右下象限疼痛就诊，影像学检查发现阑尾黏液囊肿破裂。他接受了开放性右半结肠切除术，组织病理学显示在高级别阑尾黏液性肿瘤内并发中度分化黏液腺癌——这是文献记载的首例此类病例。该病例强调了在处理罕见的并发阑尾肿瘤时早期检测、恰当手术及长期随访的必要性。
