目的:探讨原发性腹膜后黏液性囊腺瘤的临床及病理特点。方法:回顾性分析1例原发性腹膜后黏液性囊腺瘤患者的临床资料:患者女,29岁。19个月前体检时B超发现腹膜后右肾下极有3.5cm×2.4cm无回声占位性病变,内无明显血流信号。患者每6个月进行一次影像学复查,肿物体积未见明显变化。血清Ca199、Ca125、CEA等指标均在正常范围。患者在全麻下行腹腔镜腹膜后肿瘤切除术。并检索Pubmed和CBM数据库,对该疾病相关文献进行复习。结果:术后病理检查诊断为腹膜后交界性黏液性囊腺瘤。术后随访2个月,未见肿瘤复发。结论:腹膜后黏液性囊腺瘤是一种罕见的腹膜后肿瘤,诊断该病主要依靠术后病理检查。该肿瘤的体积及生长速度与肿瘤的恶性程度无确定关系。腹腔镜手术治疗腹膜后黏液性囊腺瘤安全有效。
Objective: To investigate the clinical and pathological features of primary retroperitoneal mucinous cystadenoma. Methods: The clinical data of one patient with primary retroperitoneal mucinous cystadenoma were retrospectively analyzed: The female patient, 29 years old. 19 months ago when the physical examination of B-found after the right retroperitoneal subrenal very 3.5cm × 2.4cm anechoic space-occupying lesions, no significant blood flow signal. Patients every 6 months for imaging review, no significant change in tumor volume. Serum Ca199, Ca125, CEA and other indicators are in the normal range. Patients underwent laparoscopic retroperitoneal tumor resection under general anesthesia. PubMed and CBM databases were searched to review the literature on the disease. Results: Postoperative pathological diagnosis of retroperitoneal mucinous cystadenoma. Follow-up 2 months after surgery, no tumor recurrence. Conclusion: Retroperitoneal mucinous cystadenoma is a rare retroperitoneal tumor. The diagnosis of this disease mainly depends on the postoperative pathological examination. The tumor volume and growth rate and the degree of malignancy of the tumor have no definite relationship. Laparoscopic surgery for the treatment of retroperitoneal mucinous cystadenoma is safe and effective.
