Infantile hemangiomas (strawberry birthmarks) are one of the most common skin growths seen in infancy.  They are a noncancerous overgrowth of blood vessels.  The spots generally appear as a red patch in the skin that will grow to a red raised area over a short period of time. Any infant may grow a hemangioma, but we know they are more common in certain circumstances.  The reasons for this are not clear.  Girls have them more commonly than boys.  They also occur more often in premature babies, or babies with a low birth weight.

Alopecia areata

Alopecia areata is one of the most common causes of hair loss.  This is an autoimmune condition where patches of hair are generally lost on the scalp. Though it can be more widespread or affect virtually any area of the body that has hair including the beard in men or eyebrows\eyelashes.  The condition can afflict a very broad spectrum of the population. Hands-down, alopecia areata is the most common cause of hair loss in children, but it also may affect individuals at any point during their life.
