Background:
Rhinosporidiosis is a chronic, granulomatous, and non-contagious infection, in which highly vascularized polyps (mainly present in the nasal cavity) appear. These polyps usually bleed easily.
Aims:
To present the case of a 14 year-old male suffering from an obstruction and injury of the right nostril due to a polypoid shaped-lesion with a raspberry-like appearance.
Methods:
A wide surgery resection of the base of the lesion was performed, as well as a standard histopathology procedure, including microscopic analysis with haematoxylin-eosin and Grocott staining.
Results And Conclusions:
The histopathology report indicated that the chronic inflammatory polyp was compatible with rhinosporidiosis.
Insights
Rhinosporidiosis, a nasal cavity infection causing vascular polyps, was diagnosed in a 14-year-old male. Surgical resection and histopathology confirmed the chronic inflammatory polyp.
Area of Science:
- Otorhinolaryngology
- Infectious Diseases
- Pathology
Background:
- Rhinosporidiosis is a chronic, granulomatous, non-contagious infection characterized by highly vascularized nasal polyps.
- These nasal polyps often present with significant bleeding, posing clinical challenges.
Observation:
- A 14-year-old male presented with right nostril obstruction and injury.
- The obstruction was caused by a raspberry-like, polypoid lesion within the nasal cavity.
Findings:
- Surgical resection of the polypoid lesion's base was performed.
- Histopathological analysis using hematoxylin-eosin and Grocott staining confirmed the lesion as a chronic inflammatory polyp consistent with rhinosporidiosis.
Implications:
- This case highlights the importance of histopathological confirmation for diagnosing nasal rhinosporidiosis.
- Early surgical intervention and accurate diagnosis are crucial for managing nasal cavity infections like rhinosporidiosis.
