EN has been associated with various infections and chronic inflammations. The aim of this study was to evaluate the epidemiology, etiology, clinical findings and course of EN in children.Material and Methods: A total of 14 patients diagnosed with EN between January 2005 and March 2011 at Uludag University, Pediatric Infectious Diseases Outpatient Clinic, were studied retrospectively.Results: The mean age of patients was 9.2 +/- 3.7 years (range, 3-15 years) and 57% were male. The mean duration of the skin manifestation before admission was 20.7 +/- 13.8 days (range, 7-60 days). Tularemia was the most common cause (28.6%), followed by tuberculosis (21.4%), streptococcal infection (14.2%) and gastroenteritis due to Salmonella spp. (14.2%). In one-fifth of cases, no specific cause could be identified. The duration of the recovery of lesions varied from 6 to 15 days (mean, 10.1 +/- 3.2 days). Recurrences were noted in 2 children (2 episodes in 1 child and 4 episodes in the other).Conclusion: EN has been associated with numerous diseases. This study revealed tularemia and tuberculosis as the main etiologies of EN.enChildrenErythema nodosumTularemiaTuberculosisScience & technologyLife sciences & biomedicinePediatricsArticle0004222035000041361405410.5152/ced.2011.47
