These strawberry marks are very rarely a problem to a baby's health. If a lot of these strawberry marks occur you might want to consult your pediatrician. Some are only the size of a pinhead, others are several inches in diameter. Their color is usually brown or black, but some are fawn, redish, or bluish-black. Most moles do not harm unless they are irritated.
Danger signs are when moles increase in size, become darker in color, or become more irritable.
The pigmented mole rather than the hairy one is the one most likely to cause serious trouble. Hemangioma are tangles are blood vessels so near the surface that they show. One type called the spider nevi usually appears on the face below the eyes and appears as radiating lines of blood vessels from a central spot. Warts are found in several different forms and are probably caused by a filtrable virus. Sometimes they will vanish without treatment.
