title: [Cystic fibrosis diagnosed in 36-year old man].
abstract: Cystic fibrosis (CF) is the most common autosomal recessive disorder in Caucasians. There is considerable variability in the clinical presentation and course of cystic fibrosis. Adult patients with mild symptoms are increasingly being diagnosed with CF. We present a case of a man diagnosed with CF at age 36 years. The diagnosis was suspected because of recurrent nasal polyposis, bronchiectases, male infertility, and a positive sweat tests. One CFTR mutation was identified.
  
  
  CONCLUSIONS
  1. Cystic fibrosis should be included into the differential diagnosis of chronic respiratory symptoms in adults. 2. CF patients diagnosed in adulthood usually have milder clinical course of the disease.
