The peritumoural region of a squamous cell carcinoma of the tongue when examined with light and electron microscope showed nodular bodies in the submucosa with all the distinctive features of 'sporangium and 'spores' of rhinosporidiosis. The occurrence of rhinosporidiosis in the tongue along with malignancy has not been reported hitherto. Some interesting observations and causal relationships are discussed.
