[Materials for the morphologic diagnosis of rhinosporidiosis].

A case of a nasal form of rhinosporidiosis is described in a 12-year-old girl. Its clinical diagnosis was made on the basis of histological examination of specimens taken during surgery. The inflammatory response to rhinosporidiosis was non-specific and followed by mucosal papillary hyperplasia. There were massive areas of fungal invasion and microorganisms at various stages of development, reflecting the ability of the parasite to autoinoculate and spread. The observation validates the well-established practice of surgical treatment of rhinosporidiosis that provides for coagulation or freezing of the area of the pathologic formation removed.
