From: Small cell-like change in prostatic adenocarcinoma and intraductallesions – neuroendocrine or not?
Triple cocktail showing small cell-like change in intraductal carcinoma and invasive prostatic adenocarcinoma. The monotonous small cell proliferation is seen within intraductal carcinoma, with preserved basal cell layer (A), and within invasive adenocarcinoma – with no basal cells (B). Immunohistochemistry for p63 and high molecular weigh cytokeratin (brown) and alpha-methylacyl-CoA racemase (red): A (100x) and B (100x)
