Absence of basal cells is well established as the sine qua non of prostatic adenocarcinoma.(1) However, basal cells may not identifiable on H&E sections while fibroblasts and compressed tumour cells can mimic basal cells.
Hence in morphologically equivocal cases immunohistochemistry using basal cell markers [high-molecular weight cytokeratin (HMWCK) and p63)] is used to establish a definitive diagnosis of invasive prostatic adenocarcinoma. This article is protected by copyright. All rights reserved.
