Cherry angiomas are smooth dome like bumps on the skin that are bright cherry red to purple in appearance and can develop anywhere on the body. However, angiomas are most often found on the trunk of the body and are a quite common skin problem. They vary in size, but generally can grow to about 2 mm in diameter, although in some cases they can be up to two centimeters (almost an inch) or more in diameter.
The red color and bump is due to an abnormal amount or clustering of blood vessels or capillaries. The angiomas tend to occur more often in adults older than 30 to 40, they are non-cancerous or benign growths, and are not contagious. Other names for these angiomas include senile angiomas, De Morgan sports, or Campbell de Morgan spots, named after the surgeon that discovered them.
Angiomas tend to appear spontaneously on the skin for no apparent reason. A definitive cause for these cherry red bumps is unknown.
A treatment for this skin disorder is usually not required. If a treatment is desired for cosmetic reasons or bleeding issues that are usually associated with the size of the angioma, then the options are: removal by burning (electrosurgery), removal by freezing with liquid nitrogen (cryosurgery), laser treatments such as Intense Pulsed Laser or IPL, or excision surgery.
Note that if the appearance of a cherry angioma changes, then consultation with a medical professional is recommended to ensure that no serious skin or health issues are present. Also, if they occur in an aggressive eruptive fashion, then this should be a concern because it may be a symptom of an internal malignancy.
