Rhinosporidiosis typically manifests as friable nasal polyps or masses, classically described as strawberry-like in appearance. Infection usually results from a local traumatic inoculation with the organism.


Anomalous fungal and fungal-like infections: Rhinitis is readily recognizable clinically. The causes of false-negative diagnosis are, inappropriate selection of portion of polyps containing scanty or no rhinosporidial tissue, though other portions contain rhinosporidial bodies, absence of well-developed bilamellar thick wall of sporangia, presence of only fragments of outer wall without endospores, and absence of typical rhinosporidial bodies as a result of possible immune reactions.

Further, natural animal hosts, soil habitats or water reservoirs could be analyzed to identify the ecological density of Rhinosporidium seeberi.
