Primary ovarian adenocarcinoma developing in ovarian remnant tissue ten years after laparoscopic hysterectomy and bilateral salpingo-oophorectomy for endometriosis.

Ovarian remnant syndrome is a rare but known complication of bilateral salpingo-oophorectomy associated or not with hysterectomy. This complication is frequently related to a history of multiple surgery, pelvic inflammatory disease, or endometriosis. Here we report the eighth documented case of a primary ovarian adenocarcinoma developing in an ovarian remnant but, to our knowledge, the first case to occur after laparoscopic hysterectomy and bilateral salpingo-oophorectomy. We discuss the management of pelvic masses suspected of malignancy after bilateral salpingo-oophorectomy and the possible role of endometriosis in the development of malignancy in ovarian remnant syndrome.
