- Stevens-Johnsons like rash and mucositis
- Most common in children and adolescents, with a mean age of 12 years old
- More common in males than females, 2:1
- Prodromal symptoms of cough, fever, and malaise precede
- Mucositis far out of proportion to body rash, 90% vs 10%
- Mucositis is primarily oral > ocular > genital in distribution, and can be severe
- Body rash may involve palms and soles
- Complications: dehydration, GIB, epiglottitis, blindness, pericardial effusion
- Testing: PCR nasal wash/BAL; agglutination assays IgM/IgG
- Treatment: azithromycin and supportive care; occasionally steroids; rarely IVIG
- Unlike Stevens-Johnsons, prognosis is good.
