A Rare Manifestation of Crohn's Disease: Sinonasal Granulomatosis. Report of a Case and Review of Literature

Abstract

Abstract:Crohn's disease is a granulomatous inflammatory bowel disease. Its pathologic findings include non--contiguous chronic inflammation and non--caseating granulomas, sometimes with extra--intestinal localizations. Sinonasal manifestations of Crohn's disease are quite rare and only a few cases have been reported up to date in the worldwide literature. They are characterized by chronic mucosal inflammation, obstruction, bleeding and occasionally septal perforation. We report a case of sinonasal granulomatosis revealing Crohn's disease in a 22--year--old woman and go over the available literature on sinonasal involvement in Crohn's disease.
