title: Xanthogranulomatous prostatitis: a rare entity resembling prostate adenocarcinoma with magnetic resonance image picture.
abstract: Granulomatous prostatitis, characterized by chronic granulomatous inflammation in the prostate, is rare. Xanthogranulomatous prostatitis is an even rarer granulomatous inflammation. We present a 74-year-old man who presented with lower urinary tract symptoms and elevated prostate specific antigen. A transrectal ultrasonography-guided prostate biopsy was performed, and pathological results showed foamy macrophage and inflammatory cell infiltrates, which were a distinctive feature of xanthogranulomatous prostatitis. We also present the characteristics of magnetic resonance imaging in xanthogranulomatous prostatitis which has never been previously described.
