title: [Keratoacanthoma centrifugum of Miedzinski and Kozakiewicz].
abstract: We describe the case of one patient, 54-year-old male, with a keratoacanthoma centrifugum situated on the right auricular pavilion. The injury begins as a small nodule with a keratotic innermost part that rapidly is excavated, grows centrifugally, appearing as a new lesion, an expansion of the primary one, in the posterior higher region, with the same characteristics. These lesions join and perforate the auricular cartilaginous tissue.
