Methods: Clinicopathological data were retrospectively reviewed in a total of 31 patients with pure dysgerminoma who were treated at College Clinical Medicin, Chongqing Medical University from January 1983 to October 2002. Immunohistological staining for PLAP, NSE, PRL and WT1 was performed in all 31 tumor tissues. Results: The age of the patients ranged from 12 to 42 years old (average 25 yrs). According to the clinical staging, eighteen patients (58.1%) had stage I disease, 5 (16.1%) had stage II, 6(19.4%) had stage III, and 2 (6.4%) had stage IV disease. Of the 31 cases, the positive expression rates of PLAP, NSE, PRL and WT1 were 100% (31/31), 70.9%(22/31), 3.2%(1/31) and 12.9(4/31) respectively. There was a significant relation between NSE expression and clinical stages (P<0.05) and 5 years survival rate (P<0.05). The positive expression rate of WT1 was significantly related to histological types (P<0.05). Conclusion: Dysgerminomas in earlier stages (stage I/II) are associated with a favorable prognosis. NSE positive expression is closely related with advanced tumor stage (stage III/IV). PLAP and NSE can be considered as important markers of dysgerminoma tissues, and the tumor tissues are the main resources of serum PLAP and NSE. WT1 expression correlates with poorer differentiation of dysgerminoma. The importance of PRL in dygerminoma was not certified in this study, and remains to be defined.展开更多

This is a case of comprehensive laparoscopic surgical stage of an ovarian dysgerminoma in a 10-year-old girl described. This patient was referred to the gynecology oncology unit status post left salpingo-oophorectomy through a midline incision when the histopathology showed pure dysgerminoma. We then performed the laparoscopic stage including peritoneal washing;resection of the left infundibulopelvic ligament;systematic pelvic, common iliac, and infrarenal bilateral paraaortic lymphadenectomy;and omentectomy. The uterus and right adnexum were spared to preserve future fertility. The final histopathology showed no metastatic disease (stage ovarian dysgerminoma), and patient has no evidence of recurrence after 52 months follow up. Conclusion: This is the youngest patient reported in the literature with a comprehensive laparoscopic surgical stage for ovarian neoplasm. A full laparoscopic staging for ovarian cancer in a 10-year-old girl is safe and might be considered as an alternative to the stander of care.展开更多

She had laparotomy two years earlier for a suspected fibroid. A repeat laparatomy discovered a huge left ovarian tumour;which are multilobulated and hard. She had Total Abdominal Hysterectomy and Salpingectomy with Lumpectomy on both breast. Histology report turned out as Dysgerminoma, breast, Subcutaneous Tissue and Skin Metastatic Dysgerminoma.展开更多
