Este tumor es causa de: restricción del crecimiento, anemia, trombocitopenia y polihidramnios, sobre todo en casos con corioangioma mayores de 5 cm de diámetro (corioangioma gigante). Casi todos son pequeños y pueden encontrarse en exámenes patológicos y sin complicaciones.  OBJETIVO:  Reportar un corioangioma gigante en una paciente con embarazo de término temprano, sin complicaciones fetales.  CASO CLÍNICO:  Paciente de 40 años, multigesta, en el segundo trimestre del embarazo. En la ecografía obstétrica se apreció una imagen isoecoica en el tercio distal, hacia la cara posterior, con vascularidad periférica y central al Doppler poder, de 68.4 x 63.6 mm, datos compatibles con un corioangioma placentario gigante. Reporte patológico mascroscópico: placenta monocorial monoamniótica de 505 g, disco placentario de 16 x 16 x 3.5 cm; el cordón umbilical: 8 x 12 cm, inserción central, 3 luces vasculares en su interior. Corioangioma placentario de 5 cm de diámetro mayor con zonas de calcificaciones. Los cortes histológicos reportaron: vellosidades coriales terciarias con maduración heterogénea, pequeñas y cortas, con aumento de nódulos sincitiales en el 50% del espesor placentario e infartos extensos.  CONCLUSIONES:  Para fortalecer el diagnóstico prenatal es necesario entender la influencia del corioangioma placentario en el feto y la madre; conocer los casos seleccionados que requerirán terapia fetal en caso de complicaciones. Es decisivo el seguimiento cuidadoso a través de la vigilancia ecográfica de la placenta y el feto.]]></p></abstract>

This tumor causes: growth restriction, anemia, thrombocytopenia and polyhydramnios, especially in cases with chorioangioma larger than 5 cm in diameter (giant chorioangioma). Almost all are small and can be found in pathologic examinations and without complications.  CLINICAL CASE:  A 40-year-old multigestation patient in the second trimester of pregnancy. Obstetric ultrasound showed an isoechoic image in the distal third, towards the posterior aspect, with peripheral and central vascularity on power Doppler, measuring 68.4 x 63.6 mm, data compatible with a giant placental chorioangioma. Mascroscopic pathology report: monochorionic monoamniotic placenta of 505 g, placental disc 16 x 16 x 3.5 cm; the umbilical cord: 8 x 12 cm, central insertion, 3 vascular lights inside. Placental chorioangioma 5 cm in greatest diameter with areas of calcifications. Histological sections reported: tertiary chorionic villi with heterogeneous maturation, small and short, with increased syncytial nodules in 50% of the placental thickness and extensive infarcts.  CONCLUSIONS:  To strengthen prenatal diagnosis it is necessary to understand the influence of placental chorioangioma on the fetus and the mother; to know the selected cases that will require fetal therapy in case of complications. Careful follow-up through ultrasound surveillance of the placenta and fetus is decisive.]]></p></abstract>
