Appendiceal endometriosis is a rare condition that remains difficult to diagnose preoperatively. Herein, we present a case of appendiceal endometriosis presenting as a neuroendocrine tumor. A 34-year-old Caucasian woman was found to have an appendiceal mass with a small fluid collection on routine transvaginal ultrasound. The patient denied any symptoms. Features were consistent with those of a neuroendocrine tumour of the appendix. Laparoscopic appendectomy followed by histopathology revealed endometriosis with negative cytology for malignant cells. Preoperative characteristics of appendiceal tumours in women of childbearing age should be further investigated. Establishing clinical and surgical guidelines is the key to avoid invasive procedures and related adverse outcomes.
阑尾子宫内膜异位症是一种罕见的疾病，术前仍难以诊断。在此，我们报告一例表现为神经内分泌肿瘤的阑尾子宫内膜异位症病例。一名 34 岁的白人女性在常规经阴道超声检查时发现阑尾有肿块伴少量积液。患者否认有任何症状。这些特征与阑尾神经内分泌肿瘤一致。腹腔镜阑尾切除术及组织病理学检查显示子宫内膜异位症，细胞学检查未见恶性细胞。对于育龄期妇女的阑尾肿瘤的术前特征应进一步研究。制定临床和手术指南是避免侵入性手术和相关不良后果的关键。
