Image Description
Post-atrophic hyperplasia is a variant of atrophy that consists of small basophilic-appearing acini arranged in clusters or lobules. The tight packing of acini, often around a central duct, gives it a hyperplastic appearance. At low magnification, it may be mistaken for adenocarcinoma; however, it lacks the cytologic features of cancer such as prominent nucleoli.
