title: [Lip eczema. Experience in the Contact Dermatitis Unit of a Spanish tertiary hospital].
abstract: BACKGROUND
  Lip eczema is an infrequent problem in Contact Dermatitis Units (CDU). Very few series have been published to date that show the profiles of such patients and the causes of their eczemas, and none are Spanish. The goal of this study was to analyze the epidemiological profile of the patients who attend a CDU in our setting, the main diagnoses and the relevant allergens.
  
  
  METHODS
  A retrospective review was made of the patients referred to the CDU in the 2005-2014 period. Patch tests were carried out with the extended standard series of the Spanish Research Group on Allergic Contact Dermatitis (Grupo Español de Investigación en Dermatitis Alérgica de contacto - GEIDAC), our own products and other complementary sets.
  
  
  RESULTS
  The most frequent diagnoses in the 78 patients studied were allergic contact dermatitis and atopic dermatitis. The most frequent relevant allergens were cosmetics and topical medications.
  
  
  CONCLUSIONS
  It is essential to study the patients with lip eczema with patch tests to be able to correctly determine their etiology and accordingly to carry out the most suitable treatment.
