What is a cherry angioma and what does it look like?

Blood vessel disease. Benign blood vessel proliferation, on the skin, looks like a cherry usually small spots. Most of the time no treatment required, easy to treat with cryofreezing, fulgarization or excision.
Angioma. A cherry angioma as depicted elsewhere on this site is a benign collection of blood vessels that stands up on the surface of the skin. In addition to the already mentioned treatments these are exquisitely sensitive to laser. I've treated many with excellent results.
