Metastatic ovarian disease following surgical management of grade 1 endometrial endometrioid adenocarcinoma confined to the endometrium; a case report and review of the literature.

Endometrial endometrioid type cancer is a common gynaecological cancer for which the standard surgical management includes hysterectomy and bilateral salpingo-oophorectomy. The value of oophorectomy is to remove occult ovarian disease. It is estimated that 5 % of low grade endometrioid adenocarcinoma will have concurrent ovarian involvement (3 % synchronous tumours, 2 % ovarian metastases), of which only 1 % will be microscopic. Ovarian preservation at the time of surgery can be considered, especially in early-stage disease or premenopausal women. We describe a case of metastatic ovarian disease following surgical management of grade 1 endometrial endometrioid adenocarcinoma confined to the endometrium (FIGO stage 1a), in a postmenopausal woman who declined primary oophorectomy. This case was without genetic predisposition and recurred 12 months after initial surgical treatment. This case is incongruent with what has previously been understood for FIGO stage 1a endometrial endometrioid adenocarcinoma and highlights that even disease seemingly confined to the endometrium can metastasise microscopically to the ovaries.
