ABSTRACT
A 10-week-old girl is brought in by her parents with a concern for a rash noted on the second day of life. The mother described the initial rash on a small portion of her arms and similar in appearance to blisters. The rash now appears to be red bumps and extends to the entire upper extremity including fingers and her legs. She is still feeding well and does not seem to be troubled by the rash. There is no fever.
