ABSTRACT
Resumen: En la clasificación actual de las lesiones placentarias, se describen más de un tipo de infarto placentario y otras lesiones de mala perfusión placentaria tanto maternas como fetales. Estas distintas lesiones (procesos vasculares, inflamatorios, inmunes, etc) están incorporadas a los criterios diagnósticos del Grupo de Trabajo Placentario de Amsterdam 2014. En las mismas debe considerarse el estudio de trombofilias adquiridas, sin embargo no existe suficiente evidencia para el estudio de las trombofilias hereditarias. Se realiza una revisión sobre las mismas vinculadas a esta patología.
Abstract: In the current classification of placental lesions, more than one type of placental infarction and other maternal and fetal placental malperfusion lesions are described. These different lesions (vascular, inflammatory, immune processes, etc.) are incorporated into the diagnostic criteria of the Amsterdam Placental Working Group 2014. In them, the study of acquired thrombophilias must be considered, however there is not enough evidence to study the hereditary thrombophilias. A review is carried out on them related to this pathology.

ABSTRACT
We reported a case of subchorionic placental cyst with maternal floor infarction in 32-year-old multigravida. In this case the infant without growth retardation was delivered at fuU term by repeat cesarean section. A 5.8*5cm placental cyst detected prenatally by ultrasound was shown subsequentty to be a subchorionic cyst without thrombohematoma. The cyst was unilocular and attached near the cord insertion, and it contained straw-colored fluid. There was no other placental abnormalities except placental inFarction on matemal floor with fibrin deposition. It is necessary to differentiate placental cystic lesions by ultrasonographic and pathologic examination because placental abnormalities could be associated with perinatal complications.
