title: Dysplastic changes in the anal canal epithelium in minor surgical specimens.
abstract: A ten-year consecutive material of 306 minor surgical specimens from the anal canal showed squamous dysplasia in 2.3 per cent. None of the patients developed carcinoma during an average observation time of 27 months. The average age was 64 years for dysplasia and 67 years for a corresponding series of 12 cases of anal canal carcinoma. It is concluded that all material from the anal canal should be investigated histologically.
