Prostatic hyperplastic lesions. (A) In basal cell hyperplasia, the glands have multilayered basal cells; (B) the cells have basophilic cytoplasm and bland nuclear features without prominent nucleoli; (C) the hyperplasia basal cells are positive for p63 IHC staining; (D) atypical adenomatous hyperplasia is a well-circumscribed lesion with small and crowded glands at low magnification; (E) the glands are small, round and densely packed. There are not enlarged nuclei and prominent nucleoli; (F) IHC staining is positive for 34βE12 and p63; (G) sclerosing adenosis shows the variable sized or shaped glands disorderly embed into prominent sclerotic stroma; (H) the basal cells are positive for 34βE12 in IHC staining. (H&E: A, 200×; B, E&G, 400×; D, 100×. IHC: C&H, 200×; F, 100×). IHC, immunohistochemistry.
