Svensk definition
Sjukdomar med hudutslag och hudrodnader som framträdande symtom. I äldre tider fanns sex sjukdomstillstånd med likartade hudutslag beskrivna. De var numrerade i den ordning de beskrevs. Endast den fjärde (Dukes sjukdom), den femte (erythema infectiosum) och den sjätte (exanthema subitum; tredagarsfeber) lever kvar som tillfälliga synonymer i dagens terminologi.

Only the fourth (Duke's disease), fifth (ERYTHEMA INFECTIOSUM), and sixth (EXANTHEMA SUBITUM) numeric designations survive as occasional synonyms in current terminology.
