On Rhinosporidium seeberi Wernicke with special reference to its sporulation and affinities. Pathologic Features Gross Findings Rhinosporidiosis typically manifests as friable nasal polyps or masses, classically described as strawberry-like in appearance.

Analysis of 27 cases. Although the infection is more commonly diagnosed in Asia, rhinosporidiosis was first reported in South America by Guillermo Rodolfo Seeber in two Argentine patients studied by him in72 but he did not name the etiology. Cytology can be very helpful in diagnosis in these cases, but histology is the mainstay of diagnosis.
