All authors agree on the poor prognosis of such an association, with an increased potential for evolution towards a gestational trophoblastic tumour with sometimes a molar invasion engaging the maternal and foetal prognosis. We report the case of a patient admitted for metrorrhagia at 16 weeks of amenorrhoea, and whose obstetrical ultrasound showed a twin pregnancy associating a molar pregnancy and an evolving singleton pregnancy, and whose evolution was marked by a late abortion at 20 weeks of amenorrhoea, with an early post-abortal evolution towards a non-invasive gestational trophoblastic tumour.
