He had episodes of urinary incontinence associated with pain. There were no other symptoms to suspect bowel pathology. On examination, he was found to have a tender mass in the retro-rectal plane without any evidence of rectal mucosal irregularity. He underwent an MRI of the pelvis, which showed a well-defined T2 hyperintense partly cystic lesion in the presacral region abutting the mesorectal fascia and a normal prostate gland. With a suspicion of a tailgut cyst or a duplication cyst, he underwent an excision of the presacral mass. Intraoperatively, there was a 2 \u00d7 2\u2009cm well-defined firm, cystic lesion anterior to the fifth sacral vertebra and coccyx. The lesion was adherent to the mesorectum and was excised. On histopathology, there were features of muscular stroma and bilayered glandular epithelium with clear cytoplasm conclusive of a benign ectopic prostate.<\/jats:p>","DOI":"10.1136\/bcr-2023-257319","type":"journal-article","created":{"date-parts":[[2024,4,22]],"date-time":"2024-04-22T12:35:13Z","timestamp":1713789313000},"page":"e257319","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Benign
