'''Squamous metaplasia of the anus''' is a metaplastic change of the columnar epithelium. It can histologically mimic [[anal intraepithelial neoplasia]] (AIN), especially. [[high-grade squamous intraepithelial lesion]] (HSIL). | '''Squamous metaplasia of the rectum/anus''' is a metaplastic change of the columnar epithelium of the rectum. | ||
