Extensive extramammary Paget's (EMPD) disease of the perineum in a 68-year-old man was treated by Mohs surgery. To facilitate identification of involved tissue a rapid staining carcinoembryonic antigen was used. This technique proved a useful adjunct to conventional hemotoxylin-eosin (H&E) stains. It was especially useful in highlighting involvement in areas of marked dysplasia/artifact where discrimination is often difficult. It is recommended that such a technique offers considerable benefits over H&E staining when confronted by such tissue morphology.
