Recognizing Rashes in SJIA
Learn how to tell the difference between an SJIA rash and other common skin conditions.
Q: How do I differentiate an SJIA rash from other skin conditions?
A: Although the SJIA rash can look like nearly any rash, some things set it apart, says Theresa Wampler Muskardin, MD, a pediatric rheumatologist at Hassenfeld Children’s Hospital at NYU Langone Health in New York City.
“A differentiating feature is [that] the rash of SJIA typically [accompanies] spikes of fever, which occur around certain times every day and tend to be most prominent on areas of increased warmth, such as under a child’s shirt,” she says.
Other things to watch for, according to Melissa Elder, MD, a pediatric rheumatologist at University of Florida Health Shands Children’s Hospital in Gainesville:
- The SJIA rash fades quickly and moves around; it’s not fixed in one place
- You can bring on the rash by rubbing or scratching your child’s skin – something known as Koebner’s phenomenon
