Intra-oral keratoacanthoma: an eruptive variant and review of the literature

Intra-oral keratoacanthoma, occurring in the absence of cutaneous lesions, is a rare lesion which may resemble a well-differentiated squamous cell carcinoma both clinically and histologically. A case is reported of two simultaneously occurring keratoacanthomas, of the eruptive variant, on the hard palate of a 25-year-old woman. A review of the English literature, which has identified ten documented cases to date, is presented.
