Patterned Clues in an Infant With Annular Rash and Seizures Revealing Kawasaki Disease

Kawasaki disease (KD) is a systemic vasculitis primarily affecting children, but its presentation can be highly variable, especially in young infants. While KD is classically associated with a polymorphous rash, annular or targetoid rashes are rare and can contribute to diagnostic uncertainty. Additionally, neurological complications such as seizures and aseptic meningitis are uncommon, further complicating recognition. We present a case with these atypical features, which closely mimic other conditions, including meningoencephalitis and reactive infection mucocutaneous eruption in children.
