rhinoscleroma

 [ri″no-sklĕ-ro´mah]
a granulomatous disease involving the nose and nasopharynx, due to infection by Klebsiella rhinoscleromatis, seen mainly in Egypt, Eastern Europe, and Central and South America; the growth forms hard patches or nodules, which tend to enlarge and are painful to the touch.

rhi·no·scle·ro·ma

(rī'nō-sklē-rō'mă),
A chronic granulomatous process involving the nose, upper lip, mouth, and upper air passages; starts usually as a growth of hard smooth nodules in the anterior nares that spreads backward into the pharynx, larynx, trachea, and even bronchi; it may involve the external auditory meatus and is caused by a specific bacterium, Klebsiella rhinoscleromatis.
Synonym(s): scleroma

Early diagnosis of ozena and rhinoscleroma through a fast and specific molecular method with high discriminatory power at subspecies level might contribute to a rapid therapeutic formulation and thus leading to improvement ofpatient prognosis, avoiding destructive consequences and sequelae on the respiratory mucosa.

Nasal endoscopy was done, biopsy was sent for histopathological examination which showed fragments of soft tissue showing several inflammatory cells and large histocytes with foamy cytoplasm without any evidence of infection, consistent with rhinoscleroma.
The clinical and microscopic manifestation of SHML should be differentiated from malignant lymphoreticular neoplasias, such as Hodgkin's disease and monocytic leukemia, histiocytosis, rhinoscleroma, tuberculosis, juvenile xanthogranuloma, dermatofibromas, and eosinophilic granuloma, among others.

The differential diagnoses of nasal tuberculosis include other granulomatous diseases of the nose (e.g., Wegener' s granulomatosis and lethal midline granulomatosis), specific granulomas (e.g., syphilis, rhinoscleroma, and rhinosporidiosis), and fungal granulomas (e.g., blastomycosis, histoplasmosis, and coccidioidomycosis).
