Paget cells from cases of mammary and extramammary Paget's disease were examined for carcinoembryonic antigen (CEA) and CEA-related antigens by the immunoperoxidase method. Paget cells showed a conspicuous positive reaction with antiserum to CEA, but were negative when nonspecific cross-reacting-antigen (NCA)-absorbed antiserum to CEA, or a monoclonal antibody to CEA was used as the detecting agents. Paget cells may contain large amounts of NCA antigen or CEA-related substances.
