Abstract:
In this study we report the cases of 22 pediatric patients with nodal erythema. The predominance of this condition in male patients was clear. Etiological factors were determined in 77% of the patients. In our series, the principal cause was tuberculosis (36%). We would like to point out the etiological diversity in this small series of children: streptococcal infection, gastrointestinal infection with Salmonella enteritidis or Campylobacter jejuni, cat scratch disease, infectious mononucleosis, chronic hepatitis B, Crohn's disease and pharmacological (amoxycillin). In 22% of the cases no cause was found.
