[Benign tumors of the nasal cavity, new classification and review of the literature. Report of 54 cases].

Abstract

Benign tumors of the nasal cavity is an uncommon disease and very diverse about histological variety. Theses tumors are seen at any age without specificity in semiological aspect. The diagnostic approach is based on nasal endoscopy, imaging (CT-MRI) and biopsy. In some anatomo clinical varieties the result of biopsy is so difficult and we must analyze all the tumor specimen after surgery with modern biological procedure (immunohistochemistry, molecular biology). The treatment is surgery especially with endonasal endoscopic procedure. Our series included 54 benign endonasal tumors between January 1998 and December 2008. The mean age of our population is 28 years with a female sex ratio of 1.16. Endoscopic examina­tion and a CT scan of facial bones were systematic. The tumors of nasal septum were predominant. The histological variety are dominated by vascular tumors (hemangioma) in 36 cases (66.6%) and papilloma (papilloma and inverted papilloma) in 15 cases (27.7%), two cases of fibroma (37%) and one case of leiomyoma. The treatment was surgical with an endonasal approach in 37 cases (68.5%), endonasal and endoscopic in 11 cases (20.3%) and external 6 cases (11.1%). A review of the literature on tumors of the nasal cavity is made during this study.
