These are benign tumors which are made up of small blood vessels. They appear at or near the surface of the skin. They may appear anywhere on the body and are not considered as dangerous. The most important histolorical finding is the presence of dilated and tortuous capillaries in the dermal papillae and upper dermis. They are most common after age 40.
There are many different types of angiomas-
- Cavernous angioma
- Cavernous hemangioma
- Cerebral cavernous malformation
- Cherry angioma
- venous angioma
- Spider angioma
The cause of most types of angiomas is not known. Cherry angiomas and are due to aging and do not have any known significance. Spider angiomas are more common in childhood and during pregnancy, and a few can appear on anyone. It is painless and harmless. Spider angiomas are more common in childhood and during pregnancy, and a few can appear on anyone. A spider angioma is formed when a group of blood vessels dilates in a characteristic "spider leg" pattern. A spider angioma can be seen in a healthy person without any apparent cause. But it is more common in individuals with liver disease or altered hormone levels.
The symptoms of Venous Anigomas can range to no symptoms at all to ones where the individual experiences headaches, numbness, laziness, seizures, blackouts, and other types of anigomas.. When symptoms are present, they often depend on the location of the angioma and on the strength of the angioma walls.
Treatment of Venous Angiomas is very difficult. Most times individuals will not even know that they have this illness, since symptoms do not always present themselves. If it is discovered, usually doctors take a stand of monitoring it over a period of time.
Angiomas can be treated with electrodesiccation. This can be treated only in the doctor’s offices. The treatment of angioma with electrodesiccation consists of touching the skin with an electric needle and destroying the blood vessels that make up the tumor.
Angiomas can also be treated with liquid nitrogen therapy. Liquid nitrogen is a cold, liquefied gas that is sprayed on the skin with a spray gun. This works by freezing and destroying the tumor of blood vessels.
Surgery may an option, but this is not an easy treatment, actually it is very risky depending on the location of the lesion and mostly it depends on patient basic health.
Cherry angiomas generally do not need to be treated. If they are cosmetically displeasing or prone to bleeding, angiomas may be removed by surgery, freezing (cryotherapy), burning (electrosurgery/cautery), or laser.
