ABSTRACT
Rhinosporidiosis is a chronic granulomatous infection caused by Rhinosporidium seeberi. Rhinosporidiosis has been reported from many countries but is endemic in certain parts of India and Sri Lanka. The common sites of involvement are the nose and nasopharynx followed by ocular tissue. Rhinosporidiosis is also known to involve many rare sites and may become disseminated to occur in a generalized form. Rhinosporidiosis of the parotid duct is rare and only five reported cases could be found in the literature. We report three cases of rhinosporidiosis of parotid duct presenting clinically as a parotid duct cyst. Rhinosporidiosis was diagnosed by histopathology. None of these patients had rhinosporidiosis at any other site.

Rhinosporidiosis is endemic in the state of Chhattisgarh. 462 cases were encountered during the period of 12 years from January 1994 to December 2005. Maximum incidence was seen in men in the age group of 21-30 years. Nose and nasopharynx were the commonest site (81.1%), followed by ocular tissue (14.2%). Many rare sites of involvement were encountered. Seven cases of generalized rhinosporidiosis were seen. Rhinosporidium seeberi could be easily identified in Haematoxylin and eosin stained sections. Sporangias and spores are better delineated by periodic Acid Schiff, Mayer's mucicarmine, Verhoff's vonGieson and Grocott Gomori methamine silver stain.
