● Prostate is the most common site for tuberculosis in male GU tract (involved in >90% of cases with GU tuberculosis), due to hematogenous spread from lungs or direct incasion from urethra
● Tuberculosis may perforate into urethra and extend into bladder or rectum
● Tuberculosis symptoms: fluctuant tender zones, usually bilateral, on digital rectal examination
● May cause a self limited rise in PSA in acute phase that can remain high for months
● Similar histologic findings due to intravesical treatment with bacillus Calmette-Guerin (bCG) for bladder carcinoma
● None required for bCG therapy, although rarely disseminates as tuberculosis
● Granulomas with/without caseating necrosis next to benign glands
● May calcify or become small and fibrotic, resembling carcinoma
● Causes caseating or non-caseating granulomas located next to benign prostatic glands (not engulfing them)
● Usually AFB negative
● Located along periurethral or transition zone or diffuse
