Mnemonic CRASH and burn: Conjunctivitis, Rash, Adenopathy, Strawberry tongue/oral changes, Hand and foot changes, plus burn (fever). That mnemonic IS Kawasaki disease.
The stem lists nonexudative conjunctival injection, an injected pharynx (an oral mucosal change), a polymorphic rash, and cervical lymphadenopathy, four of the classic principal criteria of Kawasaki disease, a medium vessel vasculitis that threatens the coronary arteries if untreated.
The alternatives do not fit the full pattern: measles gives Koplik spots with cough and coryza, mumps gives parotid swelling, and thrombocytopenia is merely a platelet abnormality, not a clinical mucocutaneous syndrome. The combination described is diagnostic of Kawasaki syndrome.
