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.

Page 6: Nasal Granuloma

Definition

Rhinoscleroma or scleroma is a chronic

granulomatous disease caused by gram

negative bacillus Klebsiella rhinoscleromatis

[von Frisch bacillus].

Page 7: Nasal Granuloma

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 Granuloma

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.

Page 12: Nasal Granuloma

InvestigationsX-ray PNS: Sinusitis + bone destruction

Nasopharyngoscopy: Obliteration of nasopharynx

due to adhesions between deformed V-shaped soft

palate & posterior pharyngeal wall (Gothic sign)

Flexible laryngoscopy: Subglottic stenosis

Biopsy & HPE: Mikulicz cell & Russel body

Complement fixation test: Between patient’s

serum & Frisch bacillus suspension.

Histopathology

Granulomatous tissue characterized by:

1. Mikulicz (foam) cells: histiocytes with foamy

vacuolated cytoplasm, central nucleus &

containing Frisch bacilli

2. Russel (Hyaline) body: degenerated plasma

cells with large round eosinophilic material

Rhinosporidiosis

Page 23: Nasal Granuloma

DefinitionChronic granulomatous infection of the mucous

membrane by Rhinosporidium seeberi, mainly

affecting nose & nasopharynx

Characterized by formation of friable, bleeding and

polypoidal lesions

Other sites: lips, palate, conjunctiva, epiglottis,

larynx, trachea, bronchi, skin, vulva, vagina, hand &

feet.

Page 24: Nasal Granuloma

Epidemiology88 – 95% cases in India, Pakistan & Sri Lanka

Common in Kerala, Karnataka & Tamil Nadu

Age: 20 – 40 yrs.

Sex ratio: Male : Female 4 : 1

Page 25: Nasal Granuloma

IncidenceNasal 78%

Nasopharyngeal 16%

Mixed (naso-nasopharyngeal, nasolacrimal) 05%

Bizarre (Conjunctival / Tarsal / Cutaneous) rare

Page 26: Nasal Granuloma

Clinical PresentationEpistaxis + nasal discharge + nose block

Nasal mass: papillomatous or polypoid,

granular, friable, bleeds on touch,

pedunculated or sessile, pink surface studded

with white dots [Strawberry appearance],

involves septum & turbinates

Mode of transmissionBathing in infected water; infective spores enter

via breached nasal mucosa

Droplet infection by cattle dung dust

Contact transmission: contaminated fingernails

are responsible for cutaneous lesions

Haematogenous: to other sites in infected patient

InvestigationBiopsy & Histopathological examination

Microscopic examination of nasal discharge for

spores

Sporangia of different shapes oval to round

and bursting spores are present.

Medical TreatmentDapsone: arrests maturation of spores

Dose: 100 mg OD orally (with meals) for one

year

Iron & Vitamin supplements

Page 41: Nasal Granuloma

Surgical managementGeneral anesthesia with Oro-tracheal

intubation

2% Xylocaine with adrenaline infiltrated till

surrounding mucosa appears blanched

Mass avulsed using Luc’s forceps & suction
