Embarazo gemelar con feto sano y mola completa como origen de enfermedad trofoblástica gestacional persistente: caso clínico

We describe and analyse the case of a multiple dizygotic pregnancy, formed by a genotypically and morphologically healthy foetus with a complete hydatidiform mole that ended in a preterm birth in the 2nd trimester due to maternal hypertension complications; after the evacuation of both foetus and the molar tissue, the patient developed a post-gestational Trophoblastic Neoplastic disease. We would like to focus on this pathology, looking at cases where the disease occurs in a twin gestation, explaining the diagnostic procedure and subsequent medical management of the persistent phase of gestational trophoblastic disease.
