title: [Orofacial clinical manifestations in adult patients with variable common immunodeficiency].
abstract: BACKGROUND
  Common variable immunodeficiency is the primary immunodeficiency (CVID) frequently found in adults. Its prevalence is estimated from 1:25,000 to 75,000 alive newborns; there are variations by ethnic groups, it is estimated about 50-70% in Caucasian patients. Oral cavity lesions are rarely found in adult patients with CVID, there are reports about lesions on pediatric patients mostly caused by infections.
  
  
  OBJECTIVE
  To describe the orofacial lesions (oral, maxillofacial and neck area) affecting adults with CVID.
  
  
  METHODS
  A transversal, prospective study was done in patients with CVID attended at Specialties Hospital, CMN SXXI, Mexico City. Patients where examined by the oral and maxillofacial surgeon and clinical findings were reported, then the descriptive analysis of the lesions was done.
  
  
  RESULTS
  We evaluated 26 patients, 16 female and 10 males, average age of 38.6 years. In 18/26 patients we found oral lesions on 7 different types. The most frequent was minor salivary glands hiperplasia (19/26),petechiae (12/26) and herpetic ulcers (7/26). In head and neck, we found 4 different lesions, the most common was lymphadenopathy <2cm (4/26).
  
  
  CONCLUSIONS
  The immunologic alterations associated to CVID favors the development of lesions mainly of infectious and probably autoinmune origin that affects the oral cavity and head and neck area.
