Fetal mole

1. Hemangiomas are a type of congenital vascular disease. This disease usually develops before birth (fetal period) and appears or gradually appears after birth. Hemangiopathies mainly include two cases. One is caused by an increase in the number of blood vessels (proliferation), and the other is that the number of blood vessels does not increase, but the widening and thickening of the blood vessels cause the disease. 2. Hemangiomas are commonly known as fetal nevus and vascular nevus. Traditionally, congenital skin vascular lesions are collectively referred to as hemangiomas in China. This disease is congenital and has its roots since birth.
