title: Schamberg's purpura in children: a review of 13 cases.
abstract: BACKGROUND
  Schamberg's purpura (progressive pigmentary dermatosis or pigmented purpuric dermatosis) is uncommonly described in preadolescent children.
  
  
  METHODS
  A retrospective review of cases of Schamberg's purpura with onset before 10 years of age was undertaken. Clinical and histopathologic data, as well as analytical studies including hemogram, erythrocyte sedimentation rate, serum chemistry, urinalysis, cryoglobulins, and screening for thrombotic and clotting disorders were recorded.
  
  
  RESULTS
  A total of 13 patients (3 male and 10 female) from 1 to 9 years of age (median, 5 years) had the typical cutaneous features of Schamberg's purpura. The lower limbs were affected in all patients. Lesions were unilateral in 3 cases. In 4 patients, lesions faded within 1 to 4 years, and in 1 patient lesions improved after 6 years. In 8 patients lesions persisted 1 to 7 years after. Laboratory studies were normal in all patients.
  
  
  CONCLUSIONS
  Schamberg's purpura is a chronic benign form of pigmented purpura which is occasionally seen before puberty.
