Background. Partial hydatiform mole (PHM) with an alive foetus is exceptional (0,005% to 0,01% of all pregnancies).Case presentation. here we report a case of a 33-year-old multiparous woman. The diagnosis of PHM was suspected late, at 28 weeks gestational age. After a spontaneous initiation of the labour, at 34 th weeks gestational age, she gave birth to a normal living baby. Histopathology of the placenta confirmed the PHM while the karyotype of the new-born was 46XX. The level of beta chorionic gonadotropin (βHCG) was negative after three weeks post-delivery. Currently, the child is two years old with normal psycho-motor development.Conclusions. despite the multiple and serious complications that may arise in patients with PHM, a favourable outcome is possible.
