Placental chorioangioma is a non-trophoblastic benign tumor of rare presentation. It may be associated with complications of pregnancy when larger than 4 cm. We present the case of a pregnant adolescent with 25 weeks of gestation referred for prenatal management of a giant placental chorangioma that complicated pregnancy with hydramnios and severe fetal anemia. Fetoscopic laser ablation of the main nutrient vessel of the tumor was performed for the first time in Peru, which reversed complications and improved fetal prognosis.

Background: Cardiac tumors are frequent in the fetal and infant stages, withrhabdomyoma being the most prevalent in fetal life. Its diagnosis has increased dueto ultrasound screening. Objective: To report the first Peruvian series of cases withprenatal diagnosis of fetal cardiac tumors in a maternal perinatal institute. Methods:Descriptive study of case series. The database of all fetuses with prenatal diagnosisof cardiac tumors from January 2009 to January 2021 at the Instituto NacionalMaterno Perinatal (INMP), Lima, Peru, was reviewed. These patients were followedup by telephone and in two cases echocardiographic control was performed. Results:We found 6 cases of patients diagnosed with cardiac tumors in the last 12 years inthe INMP, with reduction in size in the follow-up of all cases and association withtuberous sclerosis in half of them. Conclusions: Cardiac rhabdomyomas representth...
