  1. Rhinoscleroma

  2. Rhinoscleroma Rhinoscleromais a very rare kind of chronic inflammatory condition that is caused by bacteria called Klebsiellarhinoscleromatis.Rhinoscleroma is characterized by granulomatous swellings (lumpy firm masses composed of immune cells) in the nose and other parts of the respiratory tract, such as the paranasal sinuses, mouth, lips, larynx, trachea, and bronchi.The disease is further contracted by taking droplets or contaminated material and typically appears in patients aged 10-30 years of age.Risk factors for the disease include immunodeficiency (particularly HIV infection), poverty, poor hygiene, and prolonged contact with infected patients.

  3. Clinical Features of Rhinoscleroma Three clinical stages have been described: Catarrhal stage –Initially patients have non-specific symptoms, such as a running nose or blocked nose. As the disease progresses, the nasal discharge may contain pus and develop a foul smell. Dry crusting of the mucous membranes of the nose can occur. This stage can last for weeks to months. Granulomatous (also called hypertrophic or proliferative) stage – the mucosal tissue inside the nose becomes bluish-red, and rubbery nodules (lumps) form. As these granulomatous swellings grow, they can cause nasal enlargement and deformity. Symptoms include bleeding noses, nasal obstruction (or obstruction elsewhere in the respiratory tract), loss of the sense of smell, a hoarse voice, and thickening or numbing of the soft palate. Sclerotic or fibrotic phase – the granulation tissue is replaced by hardened scars, which can occasionally result in blocked airways.

  4. Diagnosis of Rhinoscleroma K rhinoscleromatis can be grown in the laboratory in around 50-60% of cases, using blood agar or MacConkey agar. The organisms may also be seen under the microscope using Gram, Giemsa, and silver staining. Microscopic examination of biopsy samples can reveal characteristic findings, including Mikulicz cells (large immune cells that contain the bacteria).

  5. Treatment of Rhinoscleroma Rhinoscleromacan be easily treated with the use of long-term antibiotics and surgery in patients who are having symptoms of respiratory tract obstruction. Antibiotics that have been used include streptomycin, tetracycline, rifampicin, trimethoprim-sulfamethoxazole, and ciprofloxacin. Antibiotic treatment alone may be sufficient in early stage disease. Antibiotics are generally needed for months to years to prevent recurrent infection. Surgery is often required, when granulomatous lesions or scarring are present.
