“…The mature forms of the organism, known as sporangia, contain multiple sporangiospores. 41 The trophocytes, the immature forms of R seeberi, are smaller and thinner than sporangia and do not contain endospores. 37 Sporangiospores are released at maturity and thereafter develop into trophocytes.…”

“…38 Ahluwalia suggested, however, that the causative agent of rhinosporidiosis is the cyanobacterium Microcystis aeruginosa, isolated from clinical samples as well as from water samples in which patients had been bathing. 40,41 It has been suggested that after gaining entry into the light-deprived environment in human epithelium, the photosynthetic cells of Microcystis differentiate into round bodies that characterize the histologic pattern of the disease. 41,42 No other human diseases are known to be caused by Cyanobacterium species.…”

“…Recent molecular studies of the organism have generated conflicting results. Rhinosporidium seeberi has been considered a fungus, but it was originally thought to be a protozoan parasite 6 . Early researchers noticed the similarities between R. seeberi and some aquatic parasites that lack a clear taxonomic classification.…”

Cutaneous rhinosporidiosis presents with recurrent nasal philtrum mass in southern Turkey

et al. 2008

We report a case of cutaneous rhinosporidiosis localized in the nasal philtrum. The patient's complaints started 3 months prior to being seen in our clinics. Ear, nose, and throat examination showed the presence of a polypoid lesion filling the right nostril. Complete surgical resection of the polypoid lesion provided a temporary relief as the patient developed the same lesion atin 6 weeks post-operation. The appearance and the recurrence pattern have led us to determine whether this lesion was rhinosporidiosis. Histopathological examination confirmed rhinosporidiosis. Finally, we performed complete resection followed by cauterization of the base of the mass. The infection has been reported in hot, tropical climates, and endemic zones of India and Sri Lanka. To our knowledge there is no reported case of rhinosporidiosis from southern Turkey within the subtropical Mediterranean climatic area.

“…These workers carried out phylogenentic analysis using 18s ribosomal DNA sequences. It is grouped in the order Chitridiales due to weakly developed or absent mycelia, class Mesomycetozoa family Rhinosporideacae or Olipidicea as each spherical cell is transformed into a single sporangium (Kennedy et al, 1995;Herr et al, 1999b;Ahluwalia, 2001). Class Mesomycetozoa includes numerous parasitic as well as saprophytic microorganisms, which mostly infect fishes and amphibians; although R. seeberi is only capable of infecting mammals among other members, though multiple host-specific strains may subsist (Silva et al, 2005).…”

| Rhinosporidiosis is a non-contagious, sporadic, chronic granulomatous infection of man and large domestic animals, characterised by the production of large polyps with high recurrence rate. Polyps occur mainly in nasal, ocular regions; cutaneous and disseminated forms are relatively rare. Spread of these organisms to other areas in an affected person may involve blood, lymph or auto infection. Rhinosporidiosis has been reported form more than 70 countries and mainly the reports are concentrated from Sri Lanka and Southern India. Surgical removal of the polyp will be the cure and in some cases dapsone has given some cure. From the day of inception of this disease there had been a controversy for causative agent of this condition among eukaryotic protozoan parasite or algae or fungi or prokaryotic blue green algae which finally confirmed as a fungi Rhinosporidium seeberi. Recent works by various researchers shows that R. seeberi belong to the class Mesomycetozoea. Other mystery remains in its habitat and its inability to be cultured on laboratory media. Similarly, laboratory animal infection does not yield classical form of disease as it does in human and large animals. The pathogen is so mysterious that the mechanism behind evasion of immune mechanism is also not clear. Still various aspects of disease such as mode of transmission, mechanism of infection, biology of rhinosporidiosis, immunological response and laboratory culture techniques are unresolved mysteries due to paucity of documented data which demands more exploration. This review illustrates main features of rhinosporidiosis and systematic approaches for the diagnosis and treatment of this controversial pathogen.
