A HELLP syndrome complicates a gestational trophoblastic neoplasia in a perimenopausal woman: a case report

BACKGROUND: HELLP syndrome is a combination of symptoms described as hemolysis, elevated liver enzymes and low platelets, that complicates 0.01–0.6 % of pregnancies. HELLP syndrome has been scarcely reported associated with partial moles, another rare complication of pregnancy. This manuscript describes the only reported case of HELLP syndrome associated with a complete invasive hydatiform mole. CASE PRESENTATION: We report a perimenopausal patient in prolonged remission from an uncommon high-risk invasive complete mole. The diagnosis was set in a context of early onset preeclampsia and HELLP syndrome. The development of life-threatening complications required primary hysterectomy. Postoperative hCG quickly returned to normal with EMA/CO multi-agent chemotherapy. CONCLUSION: Our patient is in prolonged remission from a complete mole complicated with EOP and HELLP syndrome. This exceptional case of complicated gestational trophoblastic neoplasia reflects a very rare condition in which several risk factors for placental ischemia are associated. Emergency hysterectomy should be considered as salvage initial treatment in such life-threatening situations.
