A live birth after bilateral salpingo-oophorectomy for seromucinous borderline ovarian tumor

Borderline ovarian tumors primarily affect younger women and are associated with favorable prognosis, making fertility-sparing surgery a viable option. However, owing to recurrence and malignant transformation risks, careful monitoring is required. Seromucinous borderline ovarian tumors, a rare subtype that is often associated with endometriosis, lack standardized guidelines for fertility-sparing surgery or infertility management following bilateral salpingo-oophorectomy with uterine preservation. We present a case of bilateral seromucinous borderline ovarian tumors stage IC3 managed with bilateral salpingo-oophorectomy, without observed recurrence, resulting in a live birth after frozen–thawed embryo transfer using embryos preserved before surgery. This case highlights the feasibility of bilateral salpingo-oophorectomy with uterine preservation and hormone replacement therapy-assisted frozen–thawed embryo transfer for seromucinous borderline ovarian tumors, emphasizing the importance of long-term surveillance and multidisciplinary management. Further research is required to establish evidence-based guidelines for seromucinous borderline ovarian tumor treatment and infertility care post-bilateral salpingo-oophorectomy.
