Representative immunohistochemical stained figures for prostatic tissue by LCA, CD68, PanCK, TROP2, and nucleophosmin. The inflammatory cells show positive reaction to LCA and CD68 (black arrows). Foamy cells stain negative to PanCK (arrow heads). The prostatic acini showed positive TROP2 staining of only basal layer (red arrows), while the surrounding stromal cells and inflammatory infiltrate were negative. The reaction to nucleophosmin was positive in both basal and luminal cells of prostatic acini (red arrows), with similar intensity of the surrounding inflammatory infiltrate (black arrows) (immunohistochemical, 200Ă—)
