A 25-year-old woman presented a challenging diagnosis of acute rheumatic fever (ARF). Initial symptoms included dry cough and three minor Jones criteria (unabating fever (38.4°C, 0d), elevated acute phase reactants (C-reactive protein, 13d) and joint pain (monoarthralgia) in her neck (0d)). ARF was diagnosed only after presentation of two major Jones criteria (polyarthritis/polyarthralgia (16d) and erythema marginatum (41d)) and positive antistreptolysin O titre (44d). Parotid swelling, peripheral oedema, elevated liver enzymes and diffuse lymphadenopathy complicated the diagnosis. Throat swab, chorea and carditis were negative or absent. Atypical ARF is challenging to recognise. There is no diagnostic test and its presentation is similar to that of other diseases. While the 2015 Jones criteria modification increased specificity of ARF diagnosis, atypical cases may still be missed, especially by physicians in developed countries. Suspicion of atypical ARF, especially after travel to high incidence regions, would allow for earlier treatment and prevention of rheumatic heart disease.
