Introduction Erythema nodosum (EN) is a dermatological entity can belong to several causes. We describe two cases, side two of the offending pathogens.
Material and method Case 1: A little boy of 7 months was admitted for febrile erythema nodosum
The history, by cons, reveals a close tuberculosis contact:the father was treated for pulmonary tuberculosis, but no chemoprophylaxis has been lavished on the family.
High inflammatory markers and a 14mm-tuberculin test are holding a post-tuberculosis EN. Antibiotic treatment allows bio-clinical resolution.
Case 2: A 5 year old girl was admitted for acute EN. She has, outside of a purulent amygdalytis, no other pathological signs.
In addition to high ESR and CRP, the results found for ASLO = 800 ui.
The rapid resolution in antibiotic anti-streptococcal etiology confirms the suspicion.
Results and discussion: The EN is the most common inflammatory nodules or panniculitis.
Investigation of an EN is often much custom and takes particular account of local epidemiology, history, geographic origin and associated signs evoking a particular pathology.
Discussion of these cases can raise some discussion points
The place still occupied worrying Mycobacterium tuberculosis in pediatric morbidity
B-hemolytic streptococcus is a public health problem
The value of prevention, secondary and tertiary, deserves an ongoing effort on targeted risk populations.
Conclusion The EN is dogmatically infectious first.
Streptococcal infection is currently the most common cause, after eliminating a primary tuberculosis.
