Abstract:
Clinical, histopathological and ultrastructural studies in three cases of rhinosporidiosis show complete remission of infection within one year of therapy with dapsone. Light and electron microscope studies confirmed arrest of the maturation of the spores and accentuated granulomatous response with fibrosis following dapsone therapy.
Insights
Dapsone therapy effectively treats rhinosporidiosis, leading to complete infection remission within a year. This treatment halts spore maturation and promotes a strong granulomatous response with fibrosis, as confirmed by microscopic studies.
Area of Science:
- Mycology
- Infectious Diseases
- Pathology
Background:
- Rhinosporidiosis is a chronic granulomatous infection caused by *Rhinosporidium seeberi*.
- Limited treatment options exist, often requiring surgical intervention.
- The need for effective medical therapies remains critical.
Observation:
- Three cases of rhinosporidiosis were treated with dapsone.
- Clinical, histopathological, and ultrastructural evaluations were performed.
- Treatment duration was within one year for all cases.
Findings:
- Complete remission of rhinosporidiosis infection was observed in all three patients.
- Light and electron microscopy revealed arrested maturation of *Rhinosporidium seeberi* spores.
- Dapsone therapy induced an accentuated granulomatous response and fibrosis.
Implications:
- Dapsone is a viable therapeutic option for rhinosporidiosis, potentially avoiding surgery.
- Understanding the mechanism of action informs future treatment strategies.
- Further research into dapsone's efficacy in larger cohorts is warranted.
