Paint by Numbers
Concerned parents bring in their toddler who has the presentation seen above. This rash extends to the bridge of the nose and a bit around the mouth, but is mostly on the cheeks. When you examine the baby, you find a red rash on the arms and legs. The rash has been there a week, and it gets worse with sun exposure. The child may have had a fever around that time. There have been no new environmental exposures, foods, or pets. You rule out child abuse.
Challenge: What is the disease? What is the cause?
