| Definitions |
Hamartoma-like growth in the placenta consisting of blood vessels. Chorioangiomas (also known as placental hemangiomas) are benign hamartomatous growth of the placenta comprising vascular tissue. The classification is controversial due to its pathologic features and clinical implications. Some authors call placental hemangiomas as true nontrophoblastic neoplastic tissues. As this abnormal vascular growth seems like the native placental tissue and it does not metastasize, some authors call it just as placental hamartoma. The general incidence is approximately 0.6 percent. Giant chorioangiomas with a diameter over 5 cm are very rare, with an incidence of one in 16-50 thousand pregnancies. Small tumors do not cause any adverse outcomes and they are asymptomatic. In contrast, tumors larger than 5 cm may lead to several complications. |
