Nasal Polyps

The histological study of nasal polyps does not reveal any specific lesions but eosinophilic infiltration nasal mucosae seems to be characteristic of nasal polyposis. The aim of this work is to study possible links between certain histological and clinical aspects in nasal polyposis. Furthermore, we attempt to compare the quantification of tissue eosinophilia according to the number of eosinophils per field with the percentage figure obtained with respect to the total of inflammatory cells. Recent study has studied 40 patients with idiopathic bilateral nasal polyposis, assessing the correlations between various clinical aspects such as their endoscopic and radiological status, association with asthma and intolerance to NSAIDs, against histological aspects of nasal polyps such as the frequency of metaplasia, fibrosis, and the degree of eosinophilic infiltration. A group of 12 healthy subjects allowed comparison of our results with healthy nasal mucosa. Results : Tissue eos...
