Study Design: Retrospective histopathological analyses of patients with nasal polyps. Methods: The study comprised 54 patients (19 females; 35 males). Group-1 patients with a diagnosis of nasal polyposis; group-2 patients with a diagnosis of antrochoanal polyps; group-3 with a diagnosis of deviation of the nasal septum as a control group. Tissues were taken during their surgery and fixed in paraffin blocks, stained to detect galectin-3, and evaluated under a light microscope. Polymorphonuclear leukocytes on the surface epithelium, glandular epithelium, and connective tissue were divided into groups according to the intensity of galectin-3 staining: "mild,'' "moderate,'' and "strong.'' The percentage of stained tissue was also graded:< 10%, 10% to 50%, 51% to 80%, and >80%. Hence, the extent of expression of galectin-3 and percentage of stained tissue was calculated. Results: Significant differences in the staining intensity of polymorphonuclear leukocytes for galectin-3 were observed between the 3 groups (P<0.01). Staining intensity in control group was significantly lower than that in group I and group II (P = 0.001; P<0.01). However, there was no significant difference between group I and group II (P>0.05). Conclusion: These findings suggest that galectin-3 has a role in the formation of nasal polyps.en10.1097/SCS.0000000000003174info:eu-repo/semantics/closedAccessAntrochonal polypapoptosisgalectin-3nasal polypArticle28128028427922968Q2WOS:000392299200067Q4
