RESUMEN
A case is described of a patient who had numerous violaceous papular lesions around the anus which appeared benign clinically, but which on histological examination showed changes of carcinoma-in-situ. The case was followed up for three years after local excision but did not recur. Such cases need careful evaluation before radical operation in view of the recently recognised entity of "Bowenoid papulosis".
