Prostatic intraepithelial neoplasia (PIN), which is dysplasia of the epithelium lining prostate glands, is a probable precursor of prostatic carcinoma. The appearance of PIN may precede carcinoma by 10 or more years. It can be divided into low grade and high grade PIN. Low grade PIN may be found even in men in middle age Abscesses may develop because of obstructed oil (sebaceous) or sweat glands, inflammation of hair follicles, or from minor breaks and punctures of the skin; abscesses may also develop after a surgical procedure. Most common bacterial organism is Staphylococcus aureus, although various other organisms can also lead to abscess formation 1. Bol Asoc Med P R. 1982 Oct;74(10):298-300. Prostatic abscess.

Prostate specific antigen (PSA) PSA is focally positive, which is common in more poorly differentiated prostatic adenocarcinoma. Lung adenocarcinoma will not be positive for PSA, so this confirms metastatic prostatic adenocarcinoma. Of note, this patient had a clinical history of a prostatic adenocarcinoma Microcystic adenocarcinoma is characterized by cystic dilation of prostatic glands to a size that is much more commonly observed in cystic change in benign prostatic glands. Finally, the cells in foamy gland adenocarcinoma display cytoplasmic vacuolization and nuclear pyknosis, features that can found in benign glands and macrophages

A 2016 retrospective study (2009-2014) that evaluated 702 consecutive pathology slides with a diagnosis of prostatic hyperplasia found that 3 cases (0.43%) were histologically misdiagnosed as prostatic hyperplasia instead of STUMP, in which there was hypercellular.

The colonic mucosa of active ulcerative colitis shows crypt abscesses in which a neutrophilic exudate is found in glandular lumens of crypts of Lieberkuhn. The submucosa shows intense inflammation.

Prostate MRI has seen rapid growth in use in recent years as an advanced diagnostic modality to detect focal areas of clinically significant prostate cancer, to identify an area for targeted biopsy and to guide management and surveillance. The increase in use has also led to increased diagnosis of incidental lesions arising from structures around the prostate This is defined as a localized accumulation of pus within the parenchyma of the prostate. Abscesses may be small or large, focal or diffuse. Smaller abscess usually coalesce to form one or more larger abscess.

The prostate gland is the most common site of tuberculosis in the male genitourinary tract; prostatic tuberculosis results from hematogenous spread from the lungs or direct invasion from the urethra. Nonspecific granulomatous prostatitis and xanthogranulomatous prostatitis are likely caused by blockage of prostatic ducts and stasis of secretions prostatic ductal adenocarcinoma. Definition: Subtype of prostatic adenocarcinoma composed of large glands lined by tall pseudostratified columnar cells. Ductal adenocarcinoma of the prostate is a subtype of adenocarcinoma that has also been termed endometrioid, endometrial, papillary or papillary ductal adenocarcinoma Intestinal type: identical to typical cystitis glandularis but with presence of goblet cells & . In patients with long-standing inflammation (indwelling catheters, calculi, etc.), intestinal type cystitis glandularis may become diffuse, at which time is suggested as a possible risk for bladder adenocarcinoma, although this association is currently controversial
