Rhinosporidiosis. A report of two cases from Arkansas
Abstract:
Two human native cases of ocular-conjunctival rhinosporidiosis from Arkansas are believed to be the first documented reports in this part of the country. The common mode of infection was accidental injury to the eye by possible contaminated soil-dust. The appearance of the polypoid growth was relatively fast, 6-16 days, and unresponsive to topical antibiotic and steroid treatment. Surgical excision, with one recurrence in one case, was the elective treatment. Both patients are asymptomatic 10-12 months after treatment, respectively, with no evidence of other recurrence, dissemination, or major complications. From 1939 to September, 1983, only nine cases of conjunctival rhinosporidiosis were reported in the United States.
Insights
Two cases of ocular-conjunctival rhinosporidiosis were reported in Arkansas, likely from contaminated soil. Surgical removal was effective, with one recurrence, but both patients recovered fully.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Mycology
Background:
- Rhinosporidiosis is a fungal infection caused by *Rhinosporidium seeberi*.
- Ocular and conjunctival involvement is rare, with limited documented cases in the United States.
- Previous reports primarily focused on endemic areas outside the US.
Observation:
- Two native human cases of ocular-conjunctival rhinosporidiosis occurred in Arkansas.
- Infection likely resulted from accidental eye injury with contaminated soil or dust.
- Rapid polypoid growth (6-16 days) was observed, unresponsive to antibiotic and steroid treatments.
Findings:
- Surgical excision was the primary treatment modality.
- One of the two patients experienced a recurrence post-surgery.
- Both patients achieved asymptomatic status 10-12 months post-treatment without further complications or dissemination.
Implications:
- This study documents the first known cases in this region of the United States.
- Highlights the importance of considering rhinosporidiosis in cases of rapidly growing conjunctival lesions.
- Emphasizes surgical management and monitoring for recurrence in ocular rhinosporidiosis.
