Definition of GranulomaGranuloma is a tumor like mass of nodular
granulation tissue with actively growing
fibroblasts and capillary buds due to
chronic inflammation with vasculitis.

Definition
Rhinoscleroma or scleroma is a chronic
granulomatous disease caused by gram
negative bacillus Klebsiella rhinoscleromatis
[von Frisch bacillus].
![Page 7: Nasal Granulomas13](https://reader035.vdocument.in/reader035/viewer/2022062320/5591be731a28ab905c8b461b/html5/thumbnails/7.jpg)
Nasal involvement staging
1. Catarrhal Stage: foul smelling purulent
nasal discharge (carpenter’s glue), not
responding to conventional antibiotics
2. Atrophic stage: foul smelling, honey-comb
colour crusting in stenosed nasal cavity
![Page 8: Nasal Granulomas13](https://reader035.vdocument.in/reader035/viewer/2022062320/5591be731a28ab905c8b461b/html5/thumbnails/8.jpg)
Nasal involvement staging3. Nodular/granulation stage: Non-ulcerative,
painless nodules which widen lower nose (Hebra
nose)
4. Cicatrizing stage: Adhesions & stenosis coarse
& distorted external nose (Tapir nose). Lower
external nose & upper lip have woody feel.
