Placenta succenturiate is a morphological anomaly of the placenta where one or more of the lobes are present at a distance, which can be of different sizes and are connected by blood vessels to the main placenta. The accessory lobe develops from the chorionic villi that did not involute from the mild chorion. The estimated incidence worldwide is 1.04%. This entity has been associated with two main risk factors, advanced maternal age and women who have undergone in vitro fertilization. We report the case of a finding of placenta succenturiate in the postpartum period, in an 18-year-old woman in her first pregnancy, with vaginal delivery, eutrophic and apparently healthy newborn was obtained. During the third period of labor the patient presented placental retention, for which manual delivery was performed, obtaining a complete placenta that upon inspection was observed the presence of an accessory lobe in the membranes, which had vascular connections with the main placenta. In conclusion, placenta succenturiata is a relatively rare morphological abnormality, diagnosed in the postpartum period, but it can be diagnosed intentionally by color Doppler ultrasound in the prenatal period. This variety of placenta carries many risks that can compromise the health and life of both the fetus and the mother.
