Prostate Specific Antigen Information for Pathologists


Kallikrein related serine protease produced by secretory epithelium, drains into ductal system. Cleaves and liquefies seminal coagulum formed after ejaculation. Clinical features Serum PSA > 4 seen in 80% with histologically documented cancer but also in 25 - 30% with nodular hyperplasia, prostatitis, infarcts, prostatic massage, cystoscopy. Elevated in 2 of 18 post-race marathon runners (Arch Pathol Lab Med 2003;127:345).

Common Uses By Pathologists:

Glycoprotein detected in benign and malignant prostate tissue. Identifies prostatic origin of most metastatic tumors, differentiates between prostatic and urothelial carcinomas. Non-prostate tumors are usually weak / negative for PSA / PAP. PSA is more sensitive (intense, diffuse staining) and specific than PAP. Microscopic (histologic) images
