Cherry angiomas are small red spots made of clustered tiny blood vessels. They are also called Campbell de Morgan spots or senile angiomas. They are harmless and very common: about half of adults have some after age 30, and about three in four people over 75. Their number usually rises with age, starting around age 40, though a few teenagers have them too.
What they look like
A cherry angioma is a round, bright cherry-red spot, from pinhead size to about a quarter inch across. It can be flat and smooth or a raised bump. Some look darker red, blue or purple, and one that has clotted can look almost black. They usually appear in groups, most often on the trunk, arms and legs, and rarely on the hands or feet. They are easier to see on lighter skin.
Why they appear
The exact cause is unknown. They tend to run in families and become more common with age. Pregnancy can bring them on, and those often fade after delivery. Certain gene changes and some chemical exposures have also been linked to them.
Rarely, many spots appear in a short time. This eruptive form has been linked in medical reports to pregnancy, certain medications and some other health conditions, so a sudden crop of new spots is something to mention to a doctor.
When to see a dermatologist
Cherry angiomas usually do not need treatment, so there is no rush for one that looks like the others. Have a spot checked if it:
- bleeds often
- grows or changes in appearance
- turns into a sore that does not heal
A few other growths can look like a cherry angioma, including pyogenic granuloma and, rarely, skin cancers such as basal cell carcinoma or a melanoma without dark pigment. A spot that is growing, bleeding or changing is a common early sign of skin cancer, which is why it is worth a look.
Because they are raised, cherry angiomas can bleed if they are injured. A small bleed can be cleaned, covered with an antibacterial ointment and bandaged.
What a visit involves
A dermatologist usually knows a cherry angioma on sight. They may also look at it with a dermatoscope, a lighted magnifier that shows the red, rounded pattern typical of these spots. If there is any doubt, a small biopsy confirms what it is.
How dermatologists remove them
Removal is optional and usually done for appearance, because a spot keeps bleeding, or because a larger spot rubs on clothing and gets irritated. Common methods are:
- Electrocautery. An electric needle treats the spot.
- Laser. A vascular laser treats the spot.
- Freezing. Liquid nitrogen freezes the spot.
- Shave removal. The spot is shaved off the skin.
An anesthetic may be used first.
What to expect afterwards
The area may be tender for a few days. Most small wounds heal well. Removal can leave a scar, depending on the removal technique used, and any removal carries some risk of a mark or a change in skin color. A treated spot can come back, and new spots can keep forming over the years.
How to choose a dermatologist
Ask which methods they use and why they suit your spots and your skin tone. Ask whether they will look at any spot you are unsure about before removing it. Before booking, ask whether your insurance covers removal, whether a referral is needed, and what the visit will cost if you pay yourself.
