Chondroma of the tongue. Report of a case and a consideration of the histogenesis of such lesions.

Chondroma of the tongue is a very rare condition. We describe a case that demonstrates unusual features in terms of its location in the tongue and the presence of noncartilaginous elements. Of the various hypotheses concerning the pathogenesis of lingual chondromas, it seems most likely that they are truly neoplasms (or hamartomas) of mesenchymal tissue that manifest metaplastic features.
