Granulomatous prostatitis is an uncommon disease of the prostate, an exocrine gland of the male reproductive system.[1] It is a form of prostatitis (prostate inflammation), resulting from infection (bacterial, viral, or fungal), BCG vaccine, malacoplakia or systemic granulomatous diseases which involve the prostate.
Pathogenesis[edit]
Prostatic secretions escape into the stroma and elicit an inflammatory response.[2]
Histopathology[edit]
Noticeable destruction of Acini, surrounded by epitheloid cells, giant cells, lymphocytes, plasma cells and dense fibrosis.[2]
Mimicry of prostate cancer[edit]
Granulomatous prostatitis can be mistaken for prostate cancer, including on rectal examination, MRI and heightened PSA scores. A biopsy differentiates.[3][4][5][6]
Causes[edit]
Some 70% of cases are idiopathic. Causes may include infection and immunological links.[6]
Prevalence[edit]
One study stated prevalence in 0.44% in routine prostectomy specimens, 0.29% in needle biopsies and 0.77% of TURP, simple prostatectomy and needle biopsy.[2]
