Histopathology and BAFF protein expression in primary and recurrent CRSwNP patients. Representative H&E images from (a) primary and (b) recurrent CRSwNP patients. (c–f) Representative IHC staining of BAFF between two groups (magnification, 200x and 400x). BAFF: B cell-activating factor; H&E: hematoxylin and eosin; CRSwNP: chronic rhinosinusitis with nasal polyps; IHC: immunohistochemistry.
