[Cystic fibrosis and uveitis in childhood and multiple sclerosis at adulthood]

We report the case of a patient with cystic fibrosis who suffered severe bilateral uveitis, with hypopyon, retinal vasculitis, and polyarthritis when he was 6 years old. No etiology could be found. Multiple sclerosis began when he was 22 years old. This panuveitis was clinically very different from the uveitis usually associated with multiple sclerosis. Polyarthritis and skin vasculitis have been reported in the course of cystic fibrosis, but no uveitis nor retinal vasculitis have been described. This raises the question of the role of multiple sclerosis and cystic fibrosis in the pathogenesis of this case of uveitis.
