Prostatic stromal hyperplasia with atypia (A) showing atypical cells in the stroma and around the benign acini, (B) showing typical cells with degenerative smudge chromatin, (C) with myxoid stroma and scattered atypical cells, and (D) with ectatic hyalinized blood vessel (hematoxylin-eosin, original magnifications ×100 [A], ×400 [B], and ×200 [C and D]). Figure 2. Immunoreactivity in prostatic stromal hyperplasia with atypia (PSHA). Strong cytoplasmic immunoreactivity of stromal cells to vimentin (A) and strong nuclear immunoreactivity for androgen receptors (B) (original magnifications ×400).
