Comprehensive laparoscopic surgical staging of ovarian dysgerminoma in a 13-year-old girl: a case report.

A case of comprehensive laparoscopic surgical staging for ovarian dysgerminoma in a 13-year-old girl is described. A 20-cm pelvic mass, rising from right adnexum, was incidentally diagnosed, and the patient underwent laparoscopic right salpingo-oophorectemy. Pathologic findings were consistent with diagnosis of pure dysgerminoma. We then performed laparoscopic staging including peritoneal washing; resection of right infundibulopelvic ligament; systematic pelvic, common iliac, and infrarenal paraaortic lymphadenectomy; appendectomy; and infracolic omentectomy. Uterus and left adnexum were spared to preserve future fertility. Currently, the patient is alive and free of disease after 21 months of follow-up. To our knowledge, this is the first reported case of comprehensive laparoscopic surgical staging for ovarian neoplasm in a 13-year-old patient.
