| Objective:11cases retroperitoneal tumors of the clinical characteristics areanalyzed and summarized,to improve the understanding of this kind of tumor, so as toavoid misdiagnosis of gynecological tumors.Methods:We collect the clinical data of11patients who first misdiagnosed asgynecologic oncology patients with retroperitoneal tumors in the First AffiliatedHospital Of Dalian Medical University from January2002to December2011.Theclinical characteristics, diagnosis, prognosis and recurrence were retrospectively clinicalanalysis.Results:11patients discovered pelvic mass in a physical examination oraccidentally. The one who diagnosed as metastatic carcinoma by ultrasound guidedpuncturing did not do the surgery.9patients diagnosed as retroperitoneal tumor in thesurgery. The other one was diagnosed by CT examination. The location of the tumorsare all in the pelvic retroperitoneal region, two beside the spine,two near the internal andexternal iliac artery and vein,one near the abdominal aorta and eight cases close to thebladder, rectum and uterus.In this group,6cases were benign,4cases were malignantand1case was borderline tumor. Pathological type included3cases of leiomyoma,2cases of benign schwannomas tumors,2cases of metastatic carcinoma, and1case ofteratoma, mucinous cystadenoma, neuroendocrine carcinoma, granule cell tumor each.In addition to one patient with systemic metastases who did not do surgery, the other10patients were completely resected in epidural anesthesia, without obvious transferringand operative death.4cases lost to follow.3cases of benign tumors (leiomyoma andschwannoma) were with good prognosis, no nerve function obstacle and withoutrecurrence. One cases of leiomyoma was done hysterectomy in November2011because of the recurrence of uterine myoma and recovery good.2cases of patients withmetastatic carcinoma were died because the whole body transferred.One case of granule cell tumor recovered well after operation in5months and no recurrence.Conclusion:Because retroperitoneal tumors rarely occur and the clinicalsymptoms often are not obvious,it is difficult to make location and nature diagnose andis easily misdiagnosed as gynecological tumors. We should collect a detailed medicalhistory, do meticulous physical examination and perfect auxiliary examination toidentify. Ultrasound, CT and MRI have high diagnostic value to retroperitoneal tumors,but they all need the clinical and radiographic doctors think highly of the disease toprevent the misdiagnosis.Surgical resection is the most effective treatment ofretroperitoneal tumor. It should be removed as clean as possible in order to reduce therecurrence rate. |
