From: T-cell phenotypes in chronic rhinosinusitis with nasal polyps in Japanese patients
Representative H-E-stained histological sections of nasal polyps (a, b) and uncinate process mucosa (c) obtained from ECRS (a), non-ECRS (b) and non-CRS (c) groups. In the ECRS group, almost all of the infiltrating cells are eosinophils (a), whereas most of the infiltrating cells are lymphocytes (black arrows) and plasma cells (red arrows) in the non-ECRS group (b). Few inflammatory cells are infiltrating in non-CRS group (c). Scale bar 100 μm
