Rhinoscleroma and rhinosporidiosis
1Dept. of Pathology, University of Texas M.D. Anderson Cancer Center, Houston 77030.
Abstract:
For North American otolaryngologists, rhinoscleroma and rhinosporidiosis are moving more into the differential diagnosis of chronic inflammatory diseases of the upper airway, particularly the nasal cavity. This change is occasioned by the influx of immigrants from parts of the world to which the diseases are endemic. Diagnosis is established by identification of the causal organisms, the readily seen Rhinosporidium seeberi for rhinosporidiosis and the more elusive Klebsiella rhinoscleromatis for rhinoscleroma.
Insights
Rhinoscleroma and rhinosporidiosis are increasingly diagnosed in North America due to immigration. Early identification of Rhinosporidium seeberi and Klebsiella rhinoscleromatis is key for accurate diagnosis of these upper airway inflammatory diseases.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Microbiology
Background:
- Rhinoscleroma and rhinosporidiosis are endemic in certain global regions.
- Immigration patterns are increasing the prevalence of these diseases in North America.
- These conditions are chronic inflammatory diseases affecting the upper airway, particularly the nasal cavity.
Purpose of the Study:
- To highlight the growing importance of rhinoscleroma and rhinosporidiosis in the differential diagnosis for North American otolaryngologists.
- To emphasize the role of microbial identification in diagnosing these conditions.
Main Methods:
- Diagnostic criteria based on identifying causative organisms.
- Microscopic identification of Rhinosporidium seeberi (rhinosporidiosis).
- Microscopic identification of Klebsiella rhinoscleromatis (rhinoscleroma).
Main Results:
- Rhinosporidiosis diagnosis is aided by the readily visible Rhinosporidium seeberi.
- Rhinoscleroma diagnosis relies on identifying the more elusive Klebsiella rhinoscleromatis.
- These diseases are becoming more common considerations in chronic upper airway inflammation.
Conclusions:
- North American otolaryngologists must consider rhinoscleroma and rhinosporidiosis in their differential diagnoses.
- Accurate diagnosis depends on the successful identification of the specific causal microorganisms.
- Increased awareness is crucial due to changing population demographics.
