Focal acantholytic dyskeratosis of the oral mucosa.

Focal acantholytic dyskeratosis represents a clinically heterogeneous group of dermatologic and mucosal lesions which share common histologic features. Oral mucosal variants of this condition are extremely uncommon. Two intraoral cases are presented, of which one depicts a solitary nodular pattern (warty dyskeratoma) and the other represents a papular lesion exhibiting multiple acantholytic foci.
