“…These results are consistent with the previously done studies as well. [15][16][17] All 30 cases were stained using IHC markers HMWCK and AMACR. In the 9 cases of BPH with suspicious foci, 6 cases (66.7%) showed intact continuous basal cell layer as highlighted by HMWCK and lack of AMACR staining in the glands; while 3 cases (33.3%) had HMWCK negative staining in the suspicious focus along with AMACR expression in the glands which led to the change in diagnosis to prostatic adenocarcinoma.…”

In view of increasing incidence of Prostate cancer with age, its early detection and management is of utmost importance. Digital rectal examination, clinical picture and USG findings are non-specific. In prostatic lesions having a suspicious morphology, IHC staining (HMWCK and AMACR) is done to distinguish benign from malignant lesions. Absence of myoepithelial layer (HMWCK negative) along with cytoplasmic granular staining in glands (AMACR positive) is consistent with malignant diagnosis.To evaluate the utility of IHC markers HMWCK and AMACR in resolving morphologically suspicious foci on Prostatic needle core biopsies and TURP specimens.Observational StudyA total of 30 cases of prostatic lesions were studied. The specimens were fixed in 10% formalin and routinely processed. Haematoxylin-Eosin (H&E) and IHC staining (HMWCK and AMACR) was done in all 30 cases.Data collected was analyzed using appropriate statistical test.A total of 30 cases including 19 cases prostatic needle core biopsies and 11 cases of TURP specimens were included in our study. Histopathological diagnosis included 1 case each of Adenosis, Atypical adenomatous hyperplasia and Transitional cell metaplasia; 9 cases of BPH with suspicious foci, 4 cases of LGPIN, 3 cases of HGPIN and 11 cases Prostatic adenocarcinoma. In 5 cases including 3 cases of BPH with suspicious foci and 1 case each of adenosis and AAH, the diagnosis was changed to Prostatic Adenocarcinoma after IHC analysis. We conclude that IHC staining should be done in cases where routine H&E sections have an ambiguous morphology. HMWCK along with AMACR is a good marker combination to differentiate Benign from Malignant lesions.
