If many and enlarged blood vessels lie unusually close together, it will appear as a hemangioma. They can be millimeters in size, as in "cherryspots", or several centimeters in size, as in infantile hemangiomas. Typical for such infantile hemangiomas is that they appear during the first months of life and gradually become smaller during childhood. So-called "cherry spots" occur in people over 40 and are red to reddish-purple, and a couple of millimeter-flat spots that are typically found on the stomach and chest. This is considered an aging phenomenon and not a disease. Angiokeratomas can appear in the abdomen, which are red, raised and easily flaky. Pyogenic granuloma is also considered a hemangioma, and is a fast-growing small bleeding lump, usually the size of a pea, that appears on the hands, feet and lip, usually after a minor injury or during pregnancy.
The reason comes from the type of hemangioma in question.
The treatment depends entirely on the type of hemangioma. The smallest hemangiomas can usually be burned away or removed with a laser. Rapidly growing or bleeding lumps in the skin, especially if they appear in a black or dark mole, do not have to be hemangioma, but skin cancer, and must be removed.
