BACKGROUND:

Chorioangioma is a vascular tumor of placental origin belonging to the group of vascular hemangiomas. It is the most frequent non-trophoblastic primary placental tumor of vascular origin.

CLINICAL CASE:

37-year-old patient with a history of: menarche at 12 years of age, beginning of active sexual life at 13 years of age, three pregnancies and two deliveries. She had only had two prenatal visits for the current pregnancy. The ultrasound reported 35 weeks of pregnancy with a 2250 g fetus. The patient had pain of obstetric origin and labor in the latent phase. The delivery was euthecological, without complications. A placental tumor was noted.

CONCLUSIONS:

Placental assessment by control ultrasound-Doppler is important to detect tumors and to avoid that, when they are small, they go unnoticed, such as chorangiomas.
