Primary appendiceal mucinous adenocarcinoma is a rare entity, while appendiceal carcinoma invading the urinary bladder is even rarer. The current study presents the case of a 54-year-old male with primary appendiceal mucinous adenocarcinoma, without gastrointestinal symptoms, presenting only with signs of bladder irritation. Abdominal computed tomography scans demonstrated a mass at the right anterior level of the bladder. During intraoperative exploration, the mass was detected to connect and adhere to the ileocecal junction, and normal appendix tissues were not found. The frozen section revealed a mucinous adenocarcinoma of the appendix and the patient immediately underwent a subsequent hemicolectomy. The present case indicates that a diagnosis of a primary appendiceal mucinous carcinoma must considered by radiologists and clinicians for patients who do not exhibit gastrointestinal symptoms, but show involvement of the nearest organs and the bladder wall.
原发性阑尾黏液腺癌是一种罕见的疾病，而侵犯膀胱的阑尾癌则更为罕见。本研究报告了一例54岁男性原发性阑尾黏液腺癌患者，该患者无胃肠道症状，仅表现出膀胱刺激症状。腹部计算机断层扫描显示膀胱右前水平有一个肿块。术中探查发现该肿块与回盲部相连并粘连，未发现正常阑尾组织。冰冻切片显示为阑尾黏液腺癌，患者随后立即接受了半结肠切除术。本病例表明，对于没有胃肠道症状，但显示最近器官和膀胱壁受累的患者，放射科医生和临床医生必须考虑原发性阑尾黏液癌的诊断。
