New Rash Needs Visit. We like to say that a picture is worth a thousand words, and a patient is worth a thousand pictures! based on your brief description it would be impossible to give you an accurate diagnosis--- i would recommend that you see your dermatologist or pediatrician in person to properly evaluate this eruption.
