Rhinosporidiosis is a chronic granulomatous disease caused by Rhinosporidium seeberi, a protistan parasite. It is characterized by polyps in the nasal cavity. It is most commonly seen in southern India and Sri Lanka. The parasite exists in both sporangial and spore forms and has a dimorphic life cycle involving both aquatic and host tissues. Clinical presentation involves polypoidal lesions in the nose that bleed easily. Treatment involves surgical removal of the polyps combined with long term dapsone medication to prevent recurrence.
