Chondroid metaplasia in a fibroepithelial polyp of the tongue

This report describes the development of chondroid metaplasia within a fibroepithelial polyp situated on the tongue. Although fibroepithelial polyps in this location are not unusual, chondroid metaplasia in such a lesion in this position has not, as far as the authors are aware, been described previously. The aetiology and the pathogenesis of the lesion are discussed.
