An eight-year-old girl is presented with three major criteria of acute rheumatic fever: polyarthritis, carditis and chorea. The diagnosis was confirmed with a history of pharyngitis 15 days prior to admission and with the findings of positive acute phase reactants such as elevated erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), elevated anti-streptolysin-O (ASO) titration, and clinical findings of polyarthritis, carditis and chorea. Patient responded well to salicylate and phenobarbital treatment. The rare association of these three major criteria in acute rheumatic fever is emphasized.
