Rare non‐trophoblastic vascular placental tumor: A diagnostic challenge

Abstract

Key Clinical Message Pathologists should consider the differential diagnoses of placental chorioangioma, which encompass chorangiosis, chorangiomatosis, chorangiocarcinoma, intervillous thrombus, and placental infarct. Abstract Chorioangiomas are rare non‐trophoblastic vascular neoplasms of the placenta, occurring in approximately 1% of pregnancies. Large chorioangiomas (>4 cm) are infrequent and associated with an increased risk of pregnancy complications. There are limited reports in the literature regarding uncomplicated cases of large placental chorioangiomas.
