We report the case of a man in his mid-60s who presented with pelvic discomfort, dysuria, reduced urine flow and fever. He had an elevated prostate-specific antigen (PSA) level of 17.5\u2009ng\/mL and abnormal findings on digital rectal examination. Multi-parametric MRI of the prostate revealed a prostate lesion suspicious for malignancy invading the rectal wall and right obturator internus muscle. However, transperineal prostate biopsies confirmed XGP with no evidence of cancer. The patient was treated with a 4-month course of ciprofloxacin, which resolved most of his symptoms, and alpha-blocker therapy was commenced to improve urine flow. This case emphasises the diagnostic challenges posed by XGP, which can mimic T4 prostate cancer and potentially lead to overtreatment. Awareness of this condition, along with systematic diagnostic strategies, is essential to avoid unnecessary interventions and optimise patient management.<\/jats:p>","DOI":"10.1136\/bcr-2025-265543","type":"journal-article","created":{"date-parts":[[2025,5,27]],"date-time":"2025-05-27T23:15:14Z","timestamp":1748387714000},"page":"e265543","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Xanthogranulomatous prostatitis: benign prostate infection masquerading as invasive prostate cancer on MRI and PET-PSMA"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1132-513X","authenticated-orcid":false,"given":"Kenneth Keen Yip","family":"Chew","sequence":"first","affiliation":[{"name":"Department of Surgery, University of New South Wales, Sydney, New South Wales, Australia"},{"name":"Urology, Liverpool Hospital, Liverpool, New South Wales, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brianna","family":"Thompson","sequence":"additional","affiliation":[{"name":"Department of Anatomical Pathology, Liverpool Hospital, Liverpool, New South Wales, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mahtab","family":"Farzin","sequence":"additional","affiliation":[{"name":"Department of Anatomical Pathology, Liverpool Hospital, Liverpool, New South Wales, Australia"},{"name":"Western Sydney University, Parramatta, New South Wales, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eddy Lee Hao","family":"Wong","sequence":"additional","affiliation":[{"name":"Urology, Liverpool Hospital, Liverpool, New South Wales, Australia"},{"name":"Campbelltown Hospital, Campbelltown, New South Wales, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2025,5,27]]},"reference":[{"key":"2025082712390373000_18.5.e265543.1","unstructured":"Bostwick DG , Cheng L .
