réaction de type 2

OBS: Cette réaction est couramment appelée érythème noueux lépreux (ENL). Mais il existe des cas sans lésions cutanées de type érythème noueux. Il est donc préférable d'utiliser le terme de réaction de type 2 et de ne parler d'ENL qu'en cas de lésions cutanées caractéristiques.

OBS: The term ENL reaction has been in use for a long time because of the crops of erythema nodosum leprosum (ENL) which often are present. However, because of the numerous symptoms in addition to ENL, some of which may occur in the absence of ENL, some authors prefer the name ""type 2 reaction"". In other words, the new name covers all the manifestations of the symptom-complex rather than a particular one, and the name ENL can be reserved for the erythema nodosum lesions when they occur.
OBS: Type 2 reactions occur in patients near to lepromatous end of the spectrum. They occur principally in treated cases, usually one to two years after the commencement of chemotherapy.
