Figure 3: Immunohistochemical stain for p63, high molecular weight cytokeratin, and AMACR. The prostatic intraepithelial neoplasia-like malignant glands are negative for p63 (brown nuclear staining) and high molecular weight cytokeratin (brown cytoplasmic staining), demonstrating the lack basal cells. AMACR (pink staining) is positive, highlighting the malignant glands. The morphology and immunohistochemistry are diagnostic of prostatic intraepithelial neoplasia-like ductal adenocarcinoma
