Abstract

Rhinosporidium seeberi causes granulomatous inflammation of mucocutaneous sites, presenting most frequently as polypoidal lesions in the nose. Sites like the conjunctiva, trachea, nasopharnyx, skin, and genitourinary tract are less frequently involved. Primary cutaneous lesion is extremely rare. We report the fine needle aspiration cytology (FNAC) of rhinosporidiosis occurring as a primary cutaneous lesion. FNAC of polypoidal and warty skin growths on leg in a 28‐year‐old male revealed numerous sporangia and spores of R. seeberi. There were no mucocutaneous lesions. Histopathologic examination confirmed the diagnosis. Globular bodies in endospores of R. seeberi are specific; their demonstration confirms diagnosis of rhinosporidiosis. FNAC or scrape cytology is economical and reliable in preoperative diagnosis of suspected and unsuspected cutaneous lesions of R. seeberi. Diagn. Cytopathol. 2009. © 2008 Wiley‐Liss, Inc.
