Since the renewed interest in keratoacanthoma, for which the credit goes to Rook and Whimster,1 this tumor has not ceased to draw the attention of dermatologists. Onset of keratoacanthoma following the administration of mercurial diuretics,2 mucous membranes as the site of localization3 on the clinical side, and production in certain animals4,5 on the experimental side have been the subjects most recently dealt with in the literature.
Recently we have had the opportunity to observe a keratoacanthoma of the benign course in a young patient with xeroderma pigmentosum.
