title: Idiopathic recurrent palmoplantar hidradenitis in children. Report of 22 cases.
abstract: BACKGROUND
  Idiopathic recurrent palmoplantar hidradenitis (IRPH) is characterized by tender erythematous plaques and nodules on the soles and, less often, the palms of young patients. To date, 10 cases of IRPH have been documented in the literature.
  
  
  METHODS
  We describe 22 pediatric patients with characteristic cutaneous and histologic findings of IRPH. Their mean age was 6 years (age range, 1.5-15 years). The onset of the disease clustered in 2 peaks, in autumn and spring. All patients had complete resolution of their lesions within 3 weeks, in 16 cases without any treatment. Ten of the 22 patients experienced more than 1 episode of IRPH.
  
  
  CONCLUSIONS
  Our study represents the largest number of cases of IRPH collected to date. Based on our data, the clinical picture is so characteristic that a histopathologic examination may not be necessary in every case. We suggest that there is a seasonality in the occurrence of this always benign and limited disease.
