BACKGROUND: Rhinosporidiosis is a rare chronic granulomatous infection presenting primarily on the mucous membrane of nasal cavities, nasopharynx and oral cavity. Rhinosporidium seeberi has been identified as the causative agent; however recent studies have implicated a waterborne organism, the cyanobacterium Microcystis aeruginosa, as the cause. It is endemic in India and Sri Lanka where 90% of all infections occur. The aim of this paper is to review literature on rhinosporidiosis and to report on one of the sporadic cases encountered in South Africa, Gauteng province.CASE PRESENTATION: A 17 year old black male patient presented with a pedunculated nasal mass causing nasal obstruction. Microscopical examination showed a polypoid mass with numerous thick walled sporangia in a background of fibrovascular connective tissue stroma with granulomatous inflammation. Fluorescent microscopy was effective in identifying the walls of the sporangia in the granulomas. A final diagnosis of nasal rhinosporidiosis was made.CONCLUSION: Rhinosporidiosis, a rare condition in our environment, has the potential to disseminate to other parts of the body. It is therefore critical for the clinicians to always consider rhinosporidiosis as a differential diagnosis when assessing patients presenting with nasal polyps.
