Rhinosporidiosis is a mucosal and cutaneous mycosis caused by Rhinosporidium seeberi.The disease is endemic in India and Sri Lanka but sporadic cases occur in the western hemisphere.The lesion produces bulky, friable mucosal polyps in the nasal cavity and nasopharynx. Less frequently the infection involves the conjunctiva, mouth, larynx, genitalia and skin.The infection results from a local traumatic inoculation with the organism while swimming or bathing in freshwater ponds, lakes or rivers. The patient complains of swelling and foreign body sensation in the nose accompanied by itching, sneezing and bleeding.
HOW IS RHINOSPORIDIOSIS DIAGNOSED?
An ENT specialist could conduct a biopsy to rule out any other disorders and to confirm a diagnosis.
HOW IS RHINOSPORIDIOSIS TREATED?
The treatment of this disorder is by surgery to remove the polyp. A procedure known as electrocoagulation might be performed at the base of the polyp after it has been removed to prevent it from reappearing. A year-long course of the drug dapsone has shown to be effective in treating this disorder.
DID YOU KNOW?
Rhinosporidiosis has been reported from about 70 countries with diverse geographical features although the highest incidence has been from India and Sri Lanka. Though most cases of human rhinosporidiosis in western temperate and middle eastern countries occurred in expatriate Indians who probably acquired the disease in their native lands, a few cases have been reported in persons, living in the west, who have never travelled to endemic areas.
