Cherry angiomas are benign papules, or small bumps, that are bright cherry red to purple in color. These lesions that can occur almost anywhere on the body, most commonly on the trunk. They are made of clusters of tiny capillaries at the surface of the skin. They often start as small red dots, and can grow to about one to two millimeters or larger. The exact cause of these lesions is not known, but they tend to increase in number and size with advancing age. These lesions are considered to be harmless in most cases, except in the rare cases of a sudden appearance of multiple angiomas, which can be a sign of an internal malignancy.
