Hemangioma (from the Greek haima - blood, angeion - vessel, oma - tumor) is a benign tumor that forms as a result of malformations of the vascular system. Hemangioma is the most common benign tumor in children. This tumor-like formation is red or cherry in color, which rises above the skin level, has clear boundaries, and on palpation resembles a foam sponge filled with blood. The color of the tumor depends on the predominance of arterial or venous blood flow in the tumor. The size of such a tumor is on average 2-3 square meters. mm up to 1000 sq. cm.
Vascular anomalies are one of the most common congenital and neonatal disorders of morphogenesis, which are divided into hemangiomas and vascular malformations. They can occur in different areas throughout the body, but are most common on the head and neck.
The actual mechanism of pathogenesis of vascular abnormalities remains unclear.
