title: Contact sensitization in patients with lower extremity dermatitis in the South Moravian region, Czech Republic.
abstract: OBJECTIVE
  The aim of the study was to determine the frequency of contact sensitization in patients with lower extremity dermatitis.
  
  
  METHODS
  Between the years 2001 and 2007, the authors investigated 462 patients (mean age 49.1 years, 196 men and 266 women) with the eczema/dermatitis localized on their lower extremities, including feet. The patients were investigated with epicutaneous tests of the European Standard Series and also with other special patch tests.
  
  
  RESULTS
  The most frequent allergens were balsam of Peru, 44/462 (9.5%); wool alcohols, 41/462 (8.9%); nickel sulphate, 39/462 (8.4%); propolis, 35/462 (7.6%); fragrance mix, 34 (7.4%) and colophony, 29/462 (6.3%).
  
  
  CONCLUSIONS
  In patients with lower extremity dermatitis the frequency of contact sensitization is still high, and therefore investigation with epicutaneous tests should belong to the routine dermatological diagnostic procedure in these patients.
