Ectopic prostate tissue (EPT) is an uncommon presentation and has been found mainly in the male urinary tract, such as the bladder, urethra, seminal vesicles, and testis. There have been extremely few cases of EPT observed out of the genitourinary tract. The present article describes one rare case of a 78-year-old male with an incidental finding of a rectal submucosal tumor, which was completely resected with a pathological diagnosis of EPT.
