Appendiceal mucinous neoplasms are a rare malignancy, but it is an important diagnostic entity. Ultrasonography and CT scan represent useful method for diagnosis; however, diagnosis is often incidental or intraoperative finding at resection for suspicion of appendicitis. Appendiceal mucinous neoplasm is commonly misdiagnosed as acute appendicitis, adnexal mass, or retroperitoneal tumors. Our case represents the importance of developing a high index of suspicion of appendiceal malignancy and mucocele rupture in patients who are planned for appendectomy. There is risk of second malignancy mostly of ovary, breast, kidney, and gastrointestinal tract simultaneously in about 30% of patients of appendiceal mucinous neoplasm. Low-grade mucinous neoplasm has excellent prognosis after standard appendectomy. Advanced stage low-grade mucinous neoplasm involving periappendiceal area or with nodal metastasis is treated by appendectomy with right hemicolectomy and lymph node dissection. We report a case of low-grade appendiceal mucinous neoplasm in a 65-year-old female with past history of surgery for benign bilateral adnexal lesions.
阑尾黏液性肿瘤是一种罕见的恶性肿瘤，但它是一个重要的诊断实体。超声和 CT 扫描是有用的诊断方法；然而，诊断通常是偶然的，或在因怀疑阑尾炎而切除时发现。阑尾黏液性肿瘤常被误诊为急性阑尾炎、附件肿块或腹膜后肿瘤。我们的病例代表了在计划行阑尾切除术的患者中，对阑尾恶性肿瘤和黏液囊肿破裂保持高度怀疑的重要性。约 30%的阑尾黏液性肿瘤患者同时存在卵巢、乳腺、肾脏和胃肠道的第二恶性肿瘤风险。低级别黏液性肿瘤在标准阑尾切除术后具有极好的预后。累及阑尾周围区域或有淋巴结转移的高级别低级别黏液性肿瘤通过阑尾切除术加右半结肠切除术和淋巴结清扫术治疗。我们报告了一例 65 岁女性的低级别阑尾黏液性肿瘤病例，该患者有双侧附件良性病变手术史。
