Abstract

Rhinosporidiosis caused by the organism Rhinosporidiumseeberi (R.seeberi) is a chronic granulomatous infection which affects the mucous membranes. The organism is considered as an aquatic protistan parasite, and is placed under the new class, the Mesomycetozoea. Rhinosporidiosisis common infection in south-east Asia and Brazil. In practice, we come across patients with involvement of the nasal cavity, nasopharynx and oropharynx.The source of infection is Soil and water.In India, the disease is endemic in the states of Chhattisgarh, Kerala, Tamil Nadu, Orissa and West Bengal. The pathogen R. seeberi was first discovered by Malbran in 1892 and two years later, the organisms causing the disease in cattle were reported in India. In 1900, Seeberwas the first person to report rhinosporidios is in the nasal region in his doctoral thesis of medicine.Later in 1966, the first case of rhinosporidiosis of the parotid duct was reported by Topazian. Seeberi classified R. seeberi organism as protozoan. Again, it was reclassified as phycomycete by Ashworth. Finally in the year 1999, after analysis of ribosomal deoxyribonucleic acidby Herr et al, the organism R. Seeberi is classified as mesomycetozoea. After the organism enters the human body, as a spore, it passes through several stages of development to form mature sporangium with thick and lamination wall. Endospores are formed within the sporangium. Nuclear condensation takes place to form endosporeswith aunique electron dense bodies measuring about 1 to 3 mm. The involvement of Rhinosporidios is in parotid duct is extremely rare, and at present very few cases reported worldwide.
