Non-prostatic lesions or structures. (A) Nephrogenic adenoma displays small glands lined by single layer of cells with fine chromatin in an edematous stroma; (B) those cells are positive for PAX-8 IHC stainining; (C) the seminal vesicle displays golden-brown amorphous material (lipofuscin) in the cytoplasm; (D) the distorted and hyperplastic rectal glands may mimic prostatic acinar adenocarcinoma due to blue-tinged mucin secretions and prominent nucleoli. (H&E: A, C&D, 400×; IHC: B, 400×). IHC, immunohistochemistry.
