title: Nonspecific granulomatous prostatitis with prostatic adenocarcinoma.
abstract: Granulomatous prostatitis is an infrequently seen entity in routine practice. One of its most common subtypes is nonspecific granulomatous prostatitis (NSGP), the etiology of which is still under debate. Such cases may be mistaken for adenocarcinoma clinically and radiologically. Histological resemblance to adenocarcinoma may arise when there is a xanthogranulomatous pattern or a prominence of epithelioid histiocytes. However, NSGP may rarely coexist with adenocarcinoma and it is critical to sample these cases thoroughly to exclude the presence of malignancy.
