title: [Immunohistochemical study of the distribution of carcinoembryonic antigen and keratin in tumors of epidermal origin. II: Keratoacanthoma and premalignant lesions].
abstract: Carcinoembryonic antigen (CEA) has been studied extensively, in association with visceral tumors and normal tissues. Although CEA has been demonstrated in sweat gland cutaneous tumors, little is known about its presence in skin and epithelial related tumors. We studied the presence of CEA and keratin in keratoacanthomas and precancerous skin lesions using immunohistochemical techniques. Its distribution related with differentiation, proliferation and malignant potential is observed. The expression of both antigens is correlated.
