Abstract:
We reported two cases of pelvic retroperitoneal schwannomawe occurred in the young unmarried female successfully resected by laparoscopic surgery.One was a 16-year-old girl presented with secondary amenorrhea.Ultrasound and MRI found the existence of an ovarian cystic and solid mass,5.3 cm × 4.5 cm in size.Laparoscopic exploration found pelvic mass completely located in the left retroperitoneal obturator fossa and complicated with rudimentary horn of the uterus.The other was a 25-year-old female and asymptomatic.Ultrasound showed a mass in the right ovary.During operation a pelvic mass was discovered in the anterior of right sacral retroperitoneum,8 cm× 6 cm in size.Two cases of retroperitoneal lesions were preoperatively misdiagnosed as ovarian mass and had densely adhered to the surrounding tissues.Histopathologic examinations confirmed to be benign schwannoma and resected radically by laparoscopy without any complications.The operation time was 120 min and 166 min,respectively.The intraoperative bleeding was 150 ml and 600 ml,respectively.The S-100 protein on pathological immunohistochemistry showed strong positivity.We deem that laparoscopic resection is necessary for diagnosis and treatment of pelvic retroperitoneal schwannomawe,being safe and effective.Complete excision is benefical to prevent recurrence.
