Laparoscopic treatment of ovarian granulosa cells tumor developed in the pelvic anterior preperitoneal space 20 years after laparotomic salpingo-oophorectomy: case report and review of literature.

Granulosa cells (GC) tumors are rare tumors which account for approximately 2-3% of all ovarian malignancies with a favorable prognosis. We report a case of a 54-year-old postmenopausal woman who developed an ovarian GC tumor in the pelvic anterior preperitoneal space 20 years after laparotomic salpingo-oophorectomy due to small part of the cyst could drop or remain entrapped into the abdominal wound during the closure of laparotomy 20 years before. Then, the patient underwent a second laparoscopic procedure with peritoneal washing, a type A radical hysterectomy, omentectomy, appendectomy, and pelvic and para-aortic lymphadenectomy. This rare case of ovarian GC tumor developing in the site of previous laparotomy demonstrates the importance of a correct and clean surgical procedure to avoid the risk of leaving even small portions of the cyst exposing the patients to either the risk of malignancy or additional surgical procedures.Precis: This rare case of ovarian granulosa cells tumor developed from residual ovarian tissue intrapped into the abdominal wound 20 years after laparotomic ovariectomy.
