Nasal polyps in cystic fibrosis.

In II polyps from patients with cystic fibrosis of the pancreas, the 
density, shape, and architecture of mucous glands were studied by the 
whole-mount method and compared with 102 non-cystic-fibrosis polyps. There were no 
differences in density which was in most polyps less than 0.5 
gland/mm.2. The shape and architecture as well as other histological appearances 
of the polyp were also alike in both groups of polyps 
which could not be distinguished. The pathogenesis of nasal polyps in 
cystic fibrosis is discussed. Apparently, it is the same as that 
of non-cystic-fibrosis polyps.
