A cherry angioma, often called a red mole, is a scarlet or bright red growth that usually appears on the trunk but can occur nearly anywhere on the body. It tends to develop after age 40, writes Dr. John Meisenheimer, a dermatologist in Orlando, Fla. In many cases, more continue to grow as you age.
Identification
Cherry angiomas are one of the most common skin growths, according to Meisenheimer. Their size can range from that of a pinhead to approximately a quarter-inch in diameter. Their surface is smooth. Doctors can usually diagnose the lesions based on appearance alone, according to MedlinePlus. Sometimes they send a sample for testing just to make sure.
Significance
Cherry angiomas aren't related to cancer and don't cause any other serious medical problems, though for some people they are a cosmetic concern. However, the average person cannot always distinguish them from a cancerous or precancerous spot, notes Meisenheimer. He recommends seeing a dermatologist about any growth that suddenly changes in size, shape or color or that becomes inflamed or itchy.
Cause
Angiomas, including cherry angiomas and other types--including spider angiomas and venous lakes--consist of excessive blood vessel growth in the skin, according to the New Zealand Dermatological Society. The root cause of the overgrowth is unknown. Meisenheimer writes that genetics factor in, with some families developing more of the red moles than others.
Treatment
If a cherry angioma remains as-is and doesn't cause you any problems, you probably don't need treatment. But if you choose to have it removed, several methods are available. A doctor can burn them off through a technique called electrocautery, notes MedlinePlus. Other options include freezing, also called cryosurgery; laser; and surgery. The size and location of the growth are factors as you and your physician choose a removal method.
Complications
If you cut a cherry angioma, it's likely to bleed profusely, Meisenheimer writes. This can be a problem if the spot is in an area you usually shave. Typically after you have one removed, no scar remains. It can grow back after such a procedure but generally doesn't. Cherry angiomas are not contagious.
