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.
