Hemangioma

Hemangioma is a benign tumor, usually in the shape of a ball, but sometimes a flatter mat, formed by a collection of excess blood vessels in an area. Because blood vessel cells are usually transparent in thin smooth muscle cells, hemangiomas are usually the color of the blood that runs through them. If the blood has a lot of oxygen, or is more arterial, the color is usually bright red. If the color is dark, the blood is usually low in oxygen, venous or possibly stagnated. more...

Hemangiomas are relatively common in newborns, and tend to disappear without treatment. The appearance of the tumor may be mistaken for a sign of physical abuse.

Types

Hemangiomas are often classified by the size of the vessel affected. For example:

  • Capillary hemangioma (or "capillary nevus hemangioma", or "superficial hemangioma")
  • Cavernous hemangioma (or "deep hemangioma") -- large vessels

Hemangiomas are mostly commonly cited as a skin related abnormality. However, various types of Hemangiomas can occur within the body. Common internal occurrences of hemangiomas include the liver, among other organs (Cavernous Hemangioma).
