This detailed photomicrograph presented by Ziad M. El-Zaatari illustrates benign prostate glands stained with PIN-4 immunohistochemistry at 400× magnification. It showcases three intersecting glands, where clear white lumina are evident. An intact basal cell layer stains brown with p63 and high-molecular weight cytokeratin, confirming benign architecture. Glandular epithelial cytoplasm shows light pink from AMACR staining, while nuclei appear blue due to hematoxylin counterstaining, highlighting the cellular composition clearly. El-Zaatari is a Surgical Pathologist at Houston Methodist Hospital.
