We present a rare case of a bleeding mass in the rectum. A male patient in his 40s was referred to hospital due to rectal bleeding. On the digital rectal examination, a polypus rectal mass was palpated. Biopsies were taken, and the magnetic resonance imaging (MRI) described a 5\u00a0cm long tumour. Multiple enlarged lymph nodes in the area were seen on MRI also outside the mesorectum with possible venous infiltration. Radiologically, it was categorized as T3bN2. Due to the patient history, a test for syphilis was requested, which confirmed the diagnosis. Hence, the rectal tumour was identified as a primary chancre of syphilis. Rectal syphilis is a rare manifestation of syphilis, but must be kept in mind as a differential diagnosis when encountering a bleeding rectal mass, especially in men having sex with men.<\/jats:p>","DOI":"10.1093\/jscr\/rjag425","type":"journal-article","created":{"date-parts":[[2026,5,15]],"date-time":"2026-05-15T11:41:40Z","timestamp":1778845300000},"source":"Crossref","is-referenced-by-count":0,"title":["Rectal syphilis presenting as a bleeding rectal tumour"],"prefix":"10.1093","volume":"2026","author":[{"given":"Kenneth","family":"Thorsen","sequence":"first","affiliation":[{"name":"Department of Gastrointestinal Surgery, Stavanger University Hospital , Leif Larsens gate 8, 4021 Stavanger ,","place":["Norway"]},{"name":"Section for Traumatology, Stavanger University Hospital , Leif Larsens gate 8, 4021 Stavanger ,","place":["Norway"]},{"name":"Department of Clinical Medicine, University of Bergen , Postbox 7804, 5020 Bergen ,","place":["Norway"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lars Peter","family":"Christersson","sequence":"additional","affiliation":[{"name":"Stavanger Medical Centre , Sverdrups gate 23, 4007 Stavanger ,","place":["Norway"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jacob Jose Fortes","family":"Goldman","sequence":"additional","affiliation":[{"name":"Department of Dermatology and Venereal Diseases, Stavanger University Hospital , Leif Larsens gate 8, 4021 Stavanger ,","place":["Norway"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ole Jacob","family":"Greve","sequence":"additional","affiliation":[{"name":"Department of Radiology, Stavanger University Hospital , Leif Larsens gate 8, 4021 Stavanger ,","place":["Norway"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dordi","family":"Lea","sequence":"additional","affiliation":[{"name":"Department of Pathology, Stavanger University Hospital , Leif Larsens gate 8, 4021 Stavanger ,","place":["Norway"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2026,6,3]]},"reference":[{"key":"2026062506245883800_ref1","doi-asserted-by":"crossref","first-page":"230","DOI":"10.1007\/s00384-023-04524-4","article-title":"The role of colonoscopy in young patients with rectal bleeding: a systematic review and meta-analysis","volume":"38","author":"Colles","year":"2023","journal-title":"Int J Color Dis"},{"key":"2026062506245883800_ref2","doi-asserted-by":"crossref","first-page":"17073","DOI":"10.1038\/nrdp.2017.73","article-title":"Syphilis","volume":"3","author":"Peeling","year":"2017","journal-title":"Nat Rev Dis Primers"},{"key":"2026062506245883800_ref3","doi-asserted-by":"crossref","first-page":"574","DOI":"10.1111\/jdv.16946","article-title":"2020 European guideline on the management of syphilis","volume":"35","author":"Janier","year":"2021","journal-title":"J Eur Acad Dermatol Venereol"},{"key":"2026062506245883800_ref4","doi-asserted-by":"crossref","first-page":"336","DOI":"10.1016\/S0140-6736(22)02348-0","article-title":"Syphilis","volume":"402","author":"Peeling","year":"2023","journal-title":"Lancet"},{"key":"2026062506245883800_ref5","doi-asserted-by":"crossref","first-page":"112","DOI":"10.4291\/wjgp.v1.i3.112","article-title":"Syphilitic proctitis mimicking rectal cancer: a case report","volume":"1","author":"Zhao","year":"2010","journal-title":"World J Gastrointest Pathophysiol"},{"key":"2026062506245883800_ref6","doi-asserted-by":"crossref","first-page":"579","DOI":"10.1016\/j.dld.2007.09.004","article-title":"Rectal cancer or rectal chancre?
