Representative tissue sections from two patients showing immunostaining for PSA and Ki67. One patient was characterized by high PSA immunoreactivity (a) showing uniform staining of high intensity in epithelial cells and a low fraction of Ki67 stained cells (b), and the other showed low PSA immunoreactivity (c) with a heterogeneous staining pattern of reduced intensity and a high fraction of Ki67 positive cells (d). Bar indicates 100 µm
