Nonspecific (idiopathic) granulomatous prostatitis associated with low-grade prostatic adenocarcinoma.
Nonspecific granulomatous prostatitis (NSGP) is uncommon and may simulate carcinoma both clinically and microscopically. Concurrent NSGP and prostatic adenocarcinoma is rare. To our knowledge this association has been documented once and it was only rarely mentioned in two large series of NSGP. We describe a 67-year-old man who presented with a history of prostatism of 1 month's duration. Suprapubic prostatectomy revealed NSGP associated with nodular hyperplasia and low-grade prostatic adenocarcinoma. The pathologist should be aware of the rare association of NSGP and prostatic adenocarcinoma. Wide sampling of the prostatectomy specimens with NSGP is mandatory to exclude an occult prostatic adenocarcinoma.
