Mongolian blue spots,a type of naevus (birthmark) on a baby's back. These feint blue spots are found singly or in groups on the lower back & buttocks at birth,when they may be mistaken for bruises. They are common in black or Asian children & are caused by a concentration of melanocytes,the cells which produce the pigment melanin,deep within the skin. They tend to disappear by the time the child is three or four years old | |
