title: Ectopic prostatic tissue of the anal canal.
abstract: A unique case is reported of ectopic prostatic tissue present within the anal submucosa from a routine ischial decubitus resection specimen. Although ectopic prostatic tissue has been reported at loci adjoining the prostate, most notably within the urethra, this case is noteworthy by merit of its disparate location.
