Oral warty dyskeratoma.

Warty dyskeratoma of the oral mucosa is a rare cause of solitary mouth lesions. Of the thirteen reported patients, only three have been described in the dermatologic literature. We now present an additional patient, and review both the medical and the dental literature on warty dyskeratoma. Various factors possibly related to its cause are discussed, including cigarette smoking, a heretofore largely unappreciated possibility.
