Supplementary figure 1 Representative eosinophilic subtypes and
histological patterns in nasal tissues of CRS patients
(A). Eosinophils infiltration in nasal tissue of ECRS and Non-eCRS.
Eosinophils were in the bottom of right panel. (B). Different
histological change in nasal tissue of 4 patterns: edematous CRS with a
great number of eosinophils (thick arrow), goblet cell hyperplasia
(triangle), thickening of the basement membrane (arrow), and the loose
stroma contains pseudocystic spaces filled with fluid (star); CRS with
hyperplasia of seromucinous glands (arrow); Fibroinflammatory CRS with
evident dilated vessels(star) and a great number of fibrocytes (arrow);
Atypical CRS with bizarre cells in stroma. The nuclei of these
”atypical” cells often tend to be hyperchromatic (arrow). Original
