This review article focuses on prostate carcinoma and underscores changes in the prostate chapter as well as those made across the entire series of the 5th edition of WHO Blue Books. Evolving and unsettled issues related to grading of intraductal carcinoma of the prostate and reporting of tertiary Gleason pattern, the definition and prognostic significance of cribriform growth pattern, and molecular pathology of prostate cancer will also be covered in this review. 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 The new edition of this authoritative reference book provides a comprehensive update on tumor classification in the same modular fashion as the previous edition with the addition of several new sections for each disease entity, including cytology, diagnostic molecular pathology, essential and desirable diagnostic criteria, and staging. 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.

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. In alignment with the new format in the 5th edition series, less common but identical neoplasms from various sites in the GU system, i.

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. The glands are lined by two cell layers: an outer low cuboidal layer and an inner layer of tall columnar mucin-secreting epithelium. These cells project inward as papillary projections.

Robinson: The proportion of cases that including or excluding IDC-P would have changed the grade in these studies is very small and would not have any significant impact. The transition between both components is usually abrupt, and the concomitant PCa is often high-grade Fig. Historical and contemporary perspectives on cribriform morphology in prostate cancer. IHC stain for p63 demonstrates loss of basal cells in the cancer glands B, x and preserved basal cell layer in benign glands elsewhere in the same core not shown. At this time, either method can be used, but pathologists should specify which of the two is used for clarity and meaningful analyses in the future. Vascular invasion, extraprostatic extension, and seminal vesicle invasion may also be observed. For this reason, the diagnosis of cribriform HGPIN on needle biopsy should be avoided as this can lead to inappropriate patient management.

Answers B - D are incorrect because osteoclasts, syncytiotrophoblasts and sometimes neoplastic cells may be multinucleated, yet they would be found in different places bone tissue, placenta and tumors, respectively. Clinical features of neuroendocrine prostate cancer. Historical and contemporary perspectives on cribriform morphology in prostate cancer. Features diagnostic of cribriform glands. The proportion of cases that including or excluding IDC-P would have changed the grade in these studies is very small and would not have any significant impact. For localized PCa, several prognostic transcript signatures or genomic classifiers have been shown to improve risk stratification additional to clinicopathological features 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. Jerasit Surintrspanont Ming Zhou. The squamous family comprises 3 tumor types: adenosquamous carcinoma, squamous cell carcinoma, and adenoid cystic basal cell carcinoma of the prostate. There is emerging evidence suggesting that IDC-P has two distinct biological pathways 36 despite the two being morphologically indistinguishable.
