[Postoperative histopathologic findings in sino-nasal polyposis].
BACKGROUND
Sino-nasal polyposis is a frequent condition in clinical practice and various pathohistological features that they exhibit can be significant for clinical picture and prognosis of the illness. Aim of this research was to examine pathohistological characteristics of sino-nasal polyposis and according to references from literature to make a pathohistological classification. MATERIALAND METHOD: In the period from May to October 2009. we have analyzed pathohistological characteristics of sino-nasal polyposis in 25 patients. All patients were operated with funcional endoscopic surgery at the Institute of Otorhinolaryngology and Maxillofacial Surgery and pathohistologycal researches were done at the Institute of Pathology, University Medical School of Belgrade.


RESULTS
Pathohistological findings in all operated patients confirmed sino-nasal polyposis and classification was establish in following pattern: 16 patients with edematous or eosinophilic polyps (64%), 6 patients with fibro-inflamatory polyps (24%) and 3 patients with hyperplasia of sero-mucous glands (12%). In 3 cases (12%) we have found atypical stromal cells but because of the rest of predominant pathohistological characteristics we did not separate these patients in additional group.


CONCLUSIONS
Edematous or eosinophilic polyps represents predominant pathohistological type which is according to data from literature.
