7) The most common form of granulomatous prostatitis consists of "nonspecific granulomatous prostatitis" and is characterized by granulomatous inflammation arranged concentrically around prostatic ducts or glands (Figure 1), and can be accompanied by giant cells and a mixture of inflammatory cells including eosinophils.
Prostatitis, a lower urinary tract infection, occurs by retrograde entry of organisms into the prostatic ducts via urethra from oral, anal, genital intercourse or masturbating practices, by hematogenous spread from other foci, or lymphatic extension from infected kidneys.
Although in earlier literature, (3) the term intraductal carcinoma of the prostate has been used variably to describe the extension of prostatic acinar carcinoma, prostatic ductal carcinoma, and urothelial carcinoma into prostatic ducts and acini, currently IDC-P refers to a lumen-spanning proliferation of malignant cells within prostatic ducts and acini caused by the spread of prostate cancer cells within preexisting prostatic glandular structures.
3] Originally, ductal carcinoma of the prostate was thought to have arisen from the prostatic utricle in the form of a mullerian ductal structure; however, immunohistochemistry studies have since shown that this rare form of prostate cancer arises from the prostatic ducts themselves.
