Occurrence/EpidemiologyThis section has been translated automatically.
The disease can occur worldwide, but is becoming increasingly rare in industrialized countries. It mainly affects children.
EtiopathogenesisThis section has been translated automatically.
The cause of rheumatic fever is angina tonsillaris or streptococcal pharyngitis caused by beta-hemolytic streptococci of the Lancefield group A. The rheumatic fever is a consequence of an infection-induced autoimmune reaction to the intrinsically local streptococcal infection.
Infection-associated anular erythema, which morphologically does not differ from erythema anulare rheumaticum, also occurs associatively in serum sickness, psittacosis, trypanosomiasis and other diseases.
LocalizationThis section has been translated automatically.
Mainly upper abdominal area (especially periumbilical) and back. Also buttocks and back of the hands (face always excluded) can be affected.
Clinical featuresThis section has been translated automatically.
Manifestation at the joints (polyarthritis), heart (endo-myo pericarditis), at the skin in the form of red-brownish, non-pruritic, anular or polycyclic erythema and so-called rheumatoid nodules as well as at the CNS as chorea minor.
The exanthema is usually accompanied by episodes of fever and is more pronounced in the late afternoon. The characteristic skin changes often occur at the beginning of acute rheumatic fever, often as concomitant symptoms of joint and heart involvement (almost always coincident with endocarditis).
In the course of acute rheumatic fever, non-figured exanthema may also occur, small red urticarial patches, papules or plaques on the knees and elbows, which regress within days or a few weeks without forming anular formations (erythema papulatum: Cockayne 1912).
