Nasal Polyps: Epidemiology, Pathology, Immunology, and Treatment
WEBNasal polyps are frequently bilateral, multiple, freely movable, and pale-gray and arise from the middle meatus of the nose. Histologically, they classically have pseudostratified ciliated columnar epithelium, thickening of the epithelial basement membrane, high stromal eosinophil count, mucin with neutral pH, few glands, and essentially no ...
WEBSinonasal polyps can have four distinct histological subtypes, which include eosinophilic polyp, chronic inflammatory polyp, hyperplastic polyp, and polyp with stromal atypia. Aim: In this review, we aim to study the presentation, classification and diagnosis of nasal polyps in the light of histopathological findings.
