A viral rash, sometimes dramatic, can last for months! Typically young adults. Some characteristic features:
- Viral illness itself can be trivial
- Usually not itchy
- Herald patch – starts with an oval scaly macule, can grow up to 5cm in diameter. Looks like ringworm, but then:
- Then multiple smaller scaly oval macules or plaques, typically chest and back – up to 20 days after appearance of herald patch. Classically “pine tree” distribution – think drooping branches extending out from midline.
