Histologic findings of the glandular parenchyma in CPS in CF versus non-CF patients. Mucous glandular parenchyma (A, arrow) with dilated glandular ducts was typical for CF patients. Serous glandular structures (B, arrow) were observed in non-CF patients. Scale bars A and B, 500μm.

3. Fig. 2
Cell populations in CPS in CF and non-CF patients. Eosinophils (A) were found in significant higher number in non-CF patients; on the other hand the number of plasma cells (B) and mast cells (C) in sinunasal polyps was significant higher in CF patients. Approximately equal numbers of CD8+ positive lymphocytes (D) were found in non-CF and CF patients. Scale bars A–D, 100μm.

Histologic findings of vascularisation in CPS in CF and non-CF patients. The examination of vascularisation pattern, visualized with CD31+ revealed no significant different between non-CF and CF patients. Scale bar, 500μm.
