Accessed March 11th, Androgen regulated serine protease Encoded by kallikrein gene KLK3 , kallikrein related peptidase 3 located on chromosome 19 Endocr Rev ; Essential features. A cytoplasmic marker that is sensitive and specific for prostatic tissue and adenocarcinoma of prostatic origin Loss of PSA in prostatic adenocarcinoma correlates to poor differentiation and poor prognosis Negative in some prostate cancers, such as basal cell, squamous cell carcinoma and sarcomatous elements of carcinosarcoma. Produced by the secretory cells of prostatic ducts and acini in males and Skene glands in females Regulated by androgen receptor Secreted into the lumen of the glands where it cleaves semenogelin I and II PLoS One ;9:e Semengolein I and II make coagulum, which mediates gel formation in semen Liquefied coagulum leads to release of sperm. Clinical features. Cytoplasmic staining positive expression is strong, granular, diffuse. Uses by pathologists. Detected in benign and malignant prostate tissue Identifies prostatic origin of most metastatic tumors Differentiates between prostatic and urothelial carcinoma More sensitive and specific than PSAP Nonprostate tumors usually negative or weak for PSA Can be used in combination with NKX3. Prognostic factors.

This review article highlights salient changes made to the prostate chapter as we have gained better understanding of the etiology, pathogenesis, and molecular pathology of prostate cancer. The following topics will be presented in detail: 1 changes in nomenclature and terminology, 2 prostatic ductal adenocarcinoma and prostatic intraepithelial neoplasia PIN -like adenocarcinoma, 3 intraductal proliferative lesions and reporting recommendations from the two major urological societies regarding intraductal carcinoma of the prostate, 4 cribriform growth pattern, 5 reporting of tertiary Gleason pattern, 6 treatment-related neuroendocrine prostatic carcinoma, and 7 molecular genetics. In addition to the updates specific to this chapter, the format of the contents had also been restructured across all volumes of the 5th edition series and that pertaining to the prostate chapter will be addressed first to provide an overview of how the new WHO Blue Book is organized.

Return to the tutorial menu. The male prostate gland is located below the bladder. The seminal vesicles are located posterior to the prostate. The urethra exits from the bladder and traverses the prostate before exiting to the penile urethra. The normal prostate is composed of glands and stroma. The glands are seen in cross section to be rounded to irregularly branching. These glands represent the terminal tubular portions of long tubuloalveolar glands that radiate from the urethra.

Such transdifferentiation is thought to be driven by epigenetic changes occurring under specific genomic conditions, including TP53 , RB1 , and PTEN loss Prostatic secretory epithelium Weak positive staining in salivary ductal cells Pathobiology ; The involved cancer cells often form single cells, cords, and nests, and would be graded as GP4 or GP5. Accordingly, it is recommended to only grade the conventional PCa component in these tumors. The new edition of WHO Blue Book acknowledges these dissimilarities but does not endorse either position because the overall evidence is insufficient, and both positions are mainly based on consensus opinions Nevertheless, the former name is still considered acceptable as are adenoid cystic carcinoma, adenoid basal cell carcinoma, and adenoid cystic carcinoma solid pattern 9. Detected in benign and malignant prostate tissue Identifies prostatic origin of most metastatic tumors Differentiates between prostatic and urothelial carcinoma More sensitive and specific than PSAP Nonprostate tumors usually negative or weak for PSA Can be used in combination with NKX3.

These two lesions have drastically different clinical implicationns; while HGPIN can be conservatively followed, AIP warrants an immediate repeat biopsy

AMACR catalyzes the racemization of alpha methyl branched carboxylic coenzyme A thioesters and this enzyme is essential in the oxidation of bile acid intermediates and branched chain fatty acids J Clin Pathol ; Phytanic acid, present in red meat and dairy products, is one of the primary substrates of AMACR and has been found to be elevated in prostate adenocarcinoma Prostate ; AMACR is important in the pharmacological activation of ibuprofen and related drugs Bioorg Chem ; Figure 2. Molecular Genetics of Prostate Cancer Molecular genetics of PCa initiation and progression, therapeutically relevant genomic alterations in metastatic PCa, and germline testing are succinctly discussed in several places in the prostate chapter. Not infrequently, prostatic glandular cells show abundant fine or coarse, brightly eosinophilic granules in the cytoplasm Fig. Prostatic acinar adenocarcinoma. The vast majority of IDC-P are associated with high-grade, high-volume PCa and occur as late events where preexisting PCa retrogradely spreads into and colonizes benign nonneoplastic ducts and acini Shah: Am J Cancer Res ; 11 Click here for information on linking to our website or using our content or images. Large and small cribriform architecture have similar adverse clinical outcome on prostate cancer biopsies. Several studies during the past decade have uniformly shown that malignant cribriform morphology, including invasive cribriform cancer and IDC-P, have a significant negative impact on clinical outcomes , albeit only a few clearly distinguished invasive and intraductal carcinoma Introduction The publication of WHO Classification of Urinary and Male Genital Tumors 5th Edition marks another major milestone in the field of genitourinary GU pathology and is the culmination of scientific advancements in recent years built upon the 4th edition published in
