妊娠中に判明した卵巣漿液粘液性境界悪性卵巣腫瘍の１症例

抄録

　A 26-year-old pregnant woman was referred to our hospital for examination of a right adnexal mass. Transvaginal ultrasound revealed a cystic tumor (approximately 8×7 cm) arising from the right adnexa. MRI revealed a suspected benign simple cyst of right ovary without any sign of nodules. We performed laparoscopic right ovarian cystectomy at 14 weeks and ６ days of gestational age (GA) to excise the tumor. The fluid inside appeared yellowish and mucinous, and the surface of the resected cyst was rough. Pathological diagnosis of the resected right ovarian cyst was right ovarian sero-mucinous borderline tumor. We recommended right adnexectomy and partial omentectomy as a secondary surgery. She consented, and laparoscopic right adnexectomy and partial omentectomy were performed at 16 weeks and ２ days GA with no operative complications. She was discharged ６ days after the operation. There was no evidence of residual tumor or metastasis. Her pregnancy course was generally good until emergency c-section surgery was performed because of placental abruption at 36 weeks and ２ days of GA. There has been no evidence of recurrence or metastasis until now.
