Representative histopathological figures for hematoxylin and eosin stained sections from prostatic cores. A There was dense granulomatous inflammation (black arrows), centered mainly around ruptured or distended acini (black arrowheads) (hematoxylin and eosin, 200×). B Higher magnification of the previous figure shows abundant plasma cells (red arrows) in the inflammatory foci, together with lymphocytes, macrophages, and neutrophils. There are foamy cells with abundant clear cytoplasm and eccentric atypical nuclei (red arrowheads), imparting a signet-ring like appearance (hematoxylin and eosin, 400×)
