Poststreptococcal reactive rheumatic syndrome.

Poststreptococcal reactive arthritis remains a poorly recognized clinical entity that is rarely considered in adults. We describe a case of poststreptococcal rheumatic syndrome in a 63-year-old woman to highlight that prolonged bone pain, night sweats, arthralgia, and laboratory evidence of active inflammation may be the principal manifestations, and that it may occur even in elderly patients. Poststreptococcal rheumatic manifestations can be viewed as a continuum extending from acute rheumatic fever with or without carditis to poststreptococcal reactive rheumatic syndrome with either reactive arthritis or systemic symptoms predominating.
