Histological views of prostatic inflammation. Control group without any inflammation, grade 0 (hematoxylin and eosin, ×100) (a). Some contact between epithelial cells and inflammatory cells (black arrow), grade 1 (hematoxylin and eosin, ×100) (b). Periglandular infiltrates adjacent to partially destroyed epithelium (black arrows), grade 2 (hematoxylin and eosin, ×100) (c). The inflammation was intensive (black arrow) and the number of inflamed acini was more than 25%, grade 3 (hematoxylin and eosin, ×100) (d).
