<unk>  is a small bright red dome-shaped bump on the skin. It ranges between 0.5 - 6 mm in diameter and usually several are present, typically on the chest and arms, and increasing in number with age. If scratched, they may bleed. They are a harmless benign tumour, containing an abnormal proliferation of blood vessels, and have no relationship to cancer. They are the most common kind of angioma, and increase with age, occurring in nearly all adults over 30 years. Campbell de Morgan is the nineteenth-century British surgeon who first described them.
