The authors' aim in this study is to discuss and review, from the presentation of a keratoacanthoma case with a clinical diagnosis of squamous cell carcinoma, the clinical and histologic criteria for a differential diagnosis between these two lesions, as well as to analyze the factors presumably involved in keratoacanthoma formation.
