[Neonatal cholestasis associated with liver failure as a clinical manifestation of cystic fibrosis].

Cystic Fibrosis is the most frequent hereditary disease in Caucasians. Its clinical presentation may be very variable. Neonatal cholestasis is a typical but rare primary clinical manifestation that usually occurs in the first 3 weeks of life. It is often associated with meconium ileus. We present the case of an infant with cystic fibrosis whose primary clinical manifestation was cholestasis and liver failure at the age of 6 weeks.
