Abstract
Purpose To study the clinical characteristics of disease development,pathology,treatment and prognosis in ovarian growing teratoma syndrome (GTS).Methods The clinical and pathological data of 1 cases of ovarian GTS were analyzed retrospectively,and the special course of disease and pathological changes were summarized.Results Ultrasound examination revealed a mass measuring 93 mm × 72 mm in the right ovary.Grossly,the tumor was cystic and solid,and solid area was mainly cauliflower like,with soft texture and small amount of hair and grease.Histopathological examination showed there were multifocal immature primitive neural tube in the solid area.Immunohistochemical staining showed the tumor cell were positive for NSE and focal positive for Syn,S-100,CD99,and CD56.In the preoperation,AFP and CA125 were 48.7 ng/mL and 84.2 U/mL.The right ovary mass and uterus,bilateral appendages,omentum and appendix were resected by radical operation,and two courses of chemotherapy postoperative were given.After 17 months,a solid peritoneal mass mesauring 47mm ×35mm × 24mm,was found in the original position by gynecological ultrasound.Grossly,it was solid and soft with some bone tissue.Histopathological examination showed a few immature cartilage and mesenchymal tissue.Tumor markers were within the normal range,the peritoneal mass and bilateral pelvic lymph nodes were excised thoroughly.A slight elevated in CA125 one month after surgery.After successive five courses of chemotherapy,no tumor recurred for 19 months follow up.Conclusion The diagnosis of GTS requires a combination of the overall course of the disease.The pathologic diagnosis of mature teratoma on postoperative recurred tumor are important indications for the differential diagnosis of GTS.Therefore,the tumor markers and abdominal and pelvic ultrasonography should be checked regularly,and reasonable treatment should be carried out aceording to the individual condition of the patient to avoid unnecessary chemotherapy.Keeping the fertility of young patients and preventing postoperative complications is the key to ensure a good prognosis.关键词
