Resumen
Objective: To describe the morphology of focal prostatic atrophy and propose a comprehensive histologic classification for a proper diagnostic recognition. Study design: A broad immunohistochemical study was performed as an adjunct to its recognition as well as a contribution to pathogenesis. Results: A morphologic continuum was seen on needle biopsies. Chronic inflammation was present only in complete atrophy. Immunohistochemical findings in partial atrophy are similar to normal acini. Luminal compartment in complete atrophy shows aberrant expression of 34βE12 favoring an intermediate phenotype. ERG negativity in all variants of atrophy may have value in the identification of the lesion. Conclusion: The morphologic findings favor a continuum probably partially preceding complete atrophy. Chronic inflammation may be a secondary phenomenon seen only in complete atrophy. Overexpression in complete atrophy of glutathione S-transferase p relates to oxidative stress possibly related to chronic ischemia, of c-Met favors the concept that intermediate cells may be target for carcinogenesis, and of CD44 may be related to the recruitment of inflammatory cells. 36 2 71 81 Herawi, M., Parwani, A.V., Irie, J., Epstein, J.I., Small glandular proliferations on needle biopsies: Most common benign mimickers of prostatic adenocarcinoma sent in for expert second opinion (2005) Am J Surg Pathol, 29, pp. 874-880 Moore, R.A., The evolution and involution of the prostate gland (1936) Am J Pathol, 12, pp. 599-624 Franks, L.M., Atrophy and hyperplasia in the prostate proper (1954) J Pathol Bacteriol, 68, pp. 617-621 Liavag, I., Atrophy and regeneration in the pathogenesis of prostatic carcinoma (1968) Acta Pathol Microbiol Scand [A], 73, pp. 338-350 Cheville, J.C., Bostwick, D.G., Postatrophic hyperplasia of the prostate: A histologic mimic of prostatic adenocarcinoma (1995) Am J Surg Pathol, 19, pp. 1068-1076 Billis, A., Magna, L.A., Inflammatory atrophy of the prostate: Prevalence and significance (2003) Arch Pathol Lab Med, 207, pp. 840-844 Billis, A., Prostatic atrophy: An autopsy study of a histologic mimic of adenocarcinoma (1998) Mod Pathol, 11, pp. 47-54 De Marzo, A.M., Marchi, V.L., Epstein, J.I., Nelson, W.G., Proliferative inflammatory atrophy of the prostate: Implications for prostatic carcinogenesis (1999) Am J Pathol, 155, pp. 1985-1992 Humphrey, P.A., Atrophy of the prostate on needle biopsy and false-positive diagnosis of malignancy (2011) J Urol, 186, pp. 2065-2066 Humphrey, P.A., (2003) Prostate Pathology, pp. 101-112. , Chicago, ASCP Press De Marzo, A.M., Platz, E.A., Epstein, J.I., Ali, T., Billis, A., Chan, T.Y., Cheng, L., Lucia, M.S., A working group classification of focal prostate atrophy lesions (2006) Am J Surg Pathol, 30, pp. 1281-1291 Postma, R., Schröder, F.H., van der Kwast, T.H., Atrophy in prostate needle biopsy cores and its relationship to prostate cancer incidence in screened men (2005) Urology, 65, pp. 745-749 Zhou, M., Netto, G.J., Epstein, J.I., (2012) Uropathology, pp. 25-30. , Philadelphia, Elsevier (editors) Billis, A., Prostatic atrophy: Clinicopathological significance (2010) Int Braz J Urol, 36, pp. 401-409 Oppenheimer, J.R., Wills, M.L., Epstein, J.I., Partial atrophy in prostate needle cores: Another diagnostic pitfall for the surgical pathologist (1998) Am J Surg Pathol, 22, pp. 440-445 Wang, W., Sun, X., Epstein, J.I., Partial atrophy on prostate needle biopsy cores: A morphologic and immunohistochemical study (2008) Am J Surg Pathol, 32, pp. 851-857 Przybycin, C.G., Kunju, L.P., Wu, A.J., Shah, R.B., Partial atrophy in prostate needle biopsies: A detailed analysis of its morphology, immunophenotype, and cellular kinetics (2008) Am J Surg Pathol, 32, pp. 58-64 Billis, A., Meirelles, L., Freitas, L.L.L., Mergence of partial and complete atrophy in prostate needle biopsies: A morphologic and immunohistochemical study (2010) Virchows Arch, 456, pp. 689-694 Putzi, M.J., De Marzo, A.M., Morphologic transitions between proliferative inflammatory atrophy and high-grade prostatic intraepithelial neoplasia (2000) Urology, 56, pp. 828-832 Wang, W., Bergh, A., Damber, J.E., Morphological transitions of proliferative inflammatory atrophy to high-grade intraepithelial neoplasia and cancer in human prostate (2009) Prostate, 69, pp. 1378-1386 De Marzo, A.M., Meeker, A.K., Zha, S., Luo, J., Nakayama, M., Platz, E.A., Isaacs, W.B., Nelson, W.G., Human prostate cancer precursors and pathobiology (2003) Urology, 62, pp. 55-62 van Leenders, G.J., Gage, W.R., Hicks, J.L., van Balken, B., Aalders, T.W., Schalken, J.A., De Marzo, A.M., Intermediate cells in human prostate epithelium are enriched in proliferative inflammatory atrophy (2003) Am J Pathol, 162, pp. 1529-1537 Worschech, A., Meirelles, L., Billis, A., Expression of AMACR (alpha-methylacyl coenzyme A racemase) in partial and complete focal atrophy on prostate needle biopsies (2009) Anal Quant Cytol Histol, 31, pp. 424-431 Ruska, K.M., Sauvageot, J., Epstein, J.I., Histology and cellular kinetics of prostatic atrophy (1998) Am J Surg Pathol, 22, pp. 1073-1077 Nakayama, M., Bennett, C.J., Hicks, J.L., Epstein, J.I., Platz, E.A., Nelson, W.G., De Marzo, A.M., Hypermetilation of the human glutatione S-transferase-p gene (GSTP1) CpG island is present in a subset of proliferative inflammatory atrophy lesions but not in normal or hyperplastic epithelium of the prostate A detailed study using laser-capture microdissection.
