title: Another look at keratoacanthoma.
abstract: In a retrospective survey over a three-year period there were found 199 patients with keratoacanthoma among 3,180 patients with malignant skin disease. The clinical features of the series are presented, with particular attention to the diagnostic error. Amongst experienced clinicians there was an 8.5% error in calling an invasive squamous cell lesion a keratoacanthoma. Pertinent features of the clinical nature of keratoacanthoma with particular reference to immunological surveillance are discussed.
