An appendiceal mucocele is a dilatation of the appendix and it is the result of benign or malignant diseases, which cause the obstruction of the appendix and the consequent accumulation of mucus secretion. The preoperative diagnosis is difficult due to non-specific clinical manifestations of the disease. We present a case of an 83-year-old female patient with a history of breast cancer that was referred to our hospital for an evaluation of a right adnexal mass discovered during her yearly follow-up. The patient underwent an exploratory laparotomy with a provisional diagnosis of a right adnexal mass. A perioperative, appendiceal mucocele was diagnosed. She underwent a formal appendectomy and histopathology of the specimen revealed a low-grade mucinous neoplasm. Appendiceal mucinous neoplasms represent a rare form of pathology among all appendectomy specimens. A preoperative diagnosis is difficult due to the lack of specific symptoms and it is often misdiagnosed as an adnexal mass. The perforation of the appendix and subsequent extravasation of its contents into the abdominal cavity may lead to pseudomyxoma peritonei, which has a very poor prognosis if not treated properly.
阑尾黏液囊肿是阑尾的扩张，它是由良性或恶性疾病导致阑尾梗阻并继而引起黏液分泌物积聚的结果。由于该疾病临床表现不具特异性，术前诊断较为困难。我们报告一例83岁女性患者，有乳腺癌病史，因年度随访时发现右侧附件区肿物前来我院评估。患者接受了剖腹探查术，初步诊断为右侧附件区肿物。术中诊断为阑尾黏液囊肿。她接受了正规的阑尾切除术，标本的组织病理学检查显示为低级别黏液性肿瘤。阑尾黏液性肿瘤在所有阑尾切除标本中是一种罕见的病理类型。由于缺乏特异性症状，术前诊断困难，且常被误诊为附件区肿物。阑尾穿孔及其内容物随后渗入腹腔可导致腹膜假黏液瘤，若治疗不当，预后很差。
