A case report of pelviscopic resection of invasive hydatidiform mole

Abstract

Rationale: Invasive moles occur in the fertile period, with about 95% occurring after previous mole removal and the remaining 5% occurring after several other pregnancies.

Patient concerns: A 27-year-old patient developed a rare invasive mole two months after a missed abortion.

Diagnoses: A transvaginal ultrasound scan revealed a 3.6 × 2.9 × 2.4 cm sized lesion with cystic vascular areas within it, within the myometrium of the right fundal posterior region of the uterus. There was no metastasis to other organs.

Interventions: After administration of methotrexate, the level of beta-human chorionic gonadotropin (ß-hCG) was elevated and liver enzymes were also markedly elevated. She wanted to retain fertility for future pregnancies. After laparoscopic removal of the myometrial invasive mole, the incision site was sutured with a 3-0 V-LocTM.

Outcomes: One year later, a natural pregnancy occurred and a cesarean section was performed at 36 weeks.

Lessons: This is the first reported case of its type. Our case demonstrated that pelviscopic removal of an invasive mole is possible if there are no other metastases, and that future pregnancy and childbirth are still feasible in women of reproductive age.
