Abstract:
Rhinoscleroma is a chronic granulomatous condition of the respiratory tract, and is not uncommon in tropical regions; particularly, Mexico, Central America and the Middle East. A few cases have been reported in North America, primarily involving immigrants from endemic countries. The causative organism is Klebsiella rhinoscleromatis, a Gram-negative coccobacillus. Diagnosis is made on the basis of culture of the organism and the characteristic pathology of Mikulicz cells on light microscopy. The condition primarily affects the upper airway, and frequently presents with nasal discharge, nasal obstruction or frontal facial pain. Despite the term 'rhinoscleroma', there may be involvement of the entire respiratory tract. Although the condition is slowly progressive, its natural course portends extensive destruction. Laryngotracheal involvement occurs in approximately 15% to 80% of cases, but patients rarely present with isolated laryngotracheal disease. In the present paper, a case of rhinoscleroma presenting with symptoms of upper airway obstruction is described.
Insights
Rhinoscleroma, a chronic respiratory infection caused by Klebsiella rhinoscleromatis, can lead to severe airway destruction. This case highlights upper airway obstruction as a key presentation of this granulomatous disease.
Area of Science:
- Infectious Diseases
- Otorhinolaryngology
- Pathology
Background:
- Rhinoscleroma is a chronic granulomatous disease affecting the respiratory tract, endemic in tropical regions.
- Caused by Klebsiella rhinoscleromatis, a Gram-negative coccobacillus.
- Diagnosis relies on microbial culture and identifying Mikulicz cells via microscopy.
Observation:
- The condition typically impacts the upper airway, presenting with symptoms like nasal obstruction and facial pain.
- While termed rhinoscleroma, it can affect the entire respiratory tract, progressing to extensive tissue destruction.
- Laryngotracheal involvement is common (15-80%), but isolated cases are rare.
Findings:
- This paper details a specific case of rhinoscleroma presenting with significant upper airway obstruction.
- The case underscores the varied clinical manifestations of this progressive infectious disease.
Implications:
- Early diagnosis and recognition of rhinoscleroma are crucial for effective management and preventing severe complications.
- Understanding the diverse presentations, including upper airway obstruction, is vital for clinicians in endemic and non-endemic areas.
- Further research into rhinoscleroma pathogenesis and treatment is warranted.

Common Respiratory Disorders
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...
