You are correct. Incomplete Kawasaki dz (IKD) was suggested by inflammation over a previously healed bacillus Calmette-Guérin scar (BCG-itis), 5 days of fever, cervical lymphadenopathy, and raised inflammatory markers. Dx criteria for classic Kawasaki dz are fever for ≥5 days, w/ ≥4 of the following: bilateral nonsuppurative conjunctivitis, oral mucosal injection, polymorphous rash, cervical lymphadenopathy, and indurative edema of the extremities, followed by desquamation. Consider IKD if these criteria are not fully met, but ≥1 of the following are present: BCG-itis, raised inflammatory markers, leukocytosis, thrombocytosis, hypoalbuminemia, anemia, increased LFTs, and/or pyuria. As BCG-itis occurs early in the course of Kawasaki dz, it is a useful sign for the early dx of pts w/ IKD. This pt’s echocardiogram showed mildly dilated coronary arteries. After she was treated w/ intravenous immunoglobulin, her fever resolved and inflammatory markers improved. The coronary artery dilatation resolved w/in 3mo.
