Abstract
A 46-year-old Asian man presented with hair growing from the anterior floor of his mouth. The diagnosis of this lesion was an oral choristoma of a ‘follicular’ variety. A choristoma is defined as an overgrowth of normal tissue at an abnormal site. Only one other case of this particular lesion has been reported to date. This article proposes mechanisms as to the aetiology of this lesion, and its inclusion in the classification of oral choristomas.
