Case Report Unusual presentation of Rhinoscleroma Dehadaray A1, Patel M2, Kaushik M3, Agrawal D4 ABSTRACT Rhinoscleroma or respiratory scleroma is a chronic, slowly progressive, inflammatory disease of the upper respiratory tract. Here we present a 35 year old male presenting with unilateral orbital complaints and non- specific findings on radiological examination, diagnosed only by histopathology as Rhinoscleroma. Due to the low incidence of this disease and its rare presentation in this case, diagnosis was a challenge, but outcome was successful.

November 2017 Case Report Introduction hinoscleroma is a chronic progressive, specific granulomatous infectious disease affecting the Rupper respiratory tract associated with Klebsiella rhinoscleromatis infection. It is endemic in Central and South America, Central Africa, Middle East, parts of Europe, India, and Indonesia [1]. It most commonly af- fects the nose [2]. Cases of Rhinoscleroma with invasion into the or- bits are rare, with very few cases reported in litera- ture. Ophthalmologists should also be aware of the Fig 1a Fig 1b disease and the problems in its management.
