Rhinoscleroma of nose extruding into oral cavity

Abstract

Rhinoscleroma (RS) is a rare chronic granulomatous disease of the upper airways affecting nasal cavity, nasopharynx, and paranasal sinuses. Klebsiella rhinoscleromatis is the causative agent of this infection and Mikulicz cells are specific to this lesion. RS is commonly seen in poorer regions such as Central Africa, South America, Middle East, India and Indonesia. It is predominantly found in rural areas and people with poor socio-economic conditions. Most patients present with chronic rhinitis, sneezing, headache and deviated nasal septum similar to current case. An association with oral cavity has not been reported previously, as per authors' knowledge. This report describes a rare case of RS of nasal cavity extending into the oral cavity.
