Hemangioma

Hemangioma (from ancient Greek αἷμα - blood and Greek ἄγγεον - vessel, vein) is a benign tumor consisting of endothelial cells forming cavities filled with blood or its components.

Hemangiomas can be found in any organ and tissue, but are most often found on the skin, bones, and lungs.

Hemangiomas are benign vascular tumors arising from abnormal proliferation of blood vessels. They consist of dilated capillaries, arterioles and venules filled with blood or hemorrhages.

Hemangioma is a benign tumor that can occur in children, adolescents, adults and the elderly. It most often appears on the face, neck, trunk and limbs. There are many types of hemangiomas, but they all have the same structure and origin.

The main reason for the development of hemangiomas is the abnormal structure of blood vessels in the prenatal period, when the embryonic blood circulation is not yet fully formed. This causes disruptions in the formation of large blood vessels, brain vessels, and the formation of hemanginomas. These defects further appear after the person is born.

The only effective treatment for hemangiomas is removal of the tumor. However, if the hemangin is located on the scalp or face, then the operation can be dangerous as it can affect important nerves and other
