General Description of Prostate Specific Antigen .
Prostate-specific antigen (PSA) is a serine protease member of the human glandular kallikrein family. It is synthesized in the prostate ductal and acinar epithelium and diffused into serum. It is found in normal, hyperplastic, and malignant prostate tissue. Low expression of PSA has been reported in other normal or tumor tissues such as urethral, periurethral,and perianal glands, salivary duct carcinoma, and rare mammary carcinomas. Although low PSA expression has been found in other tissues, PSA is still a specific and sensitive marker for immunohistochemical analysis of tumors with prostate epithelial cell differentiation. It is valuable in the identification of metastatic tumors of prostatic origin.

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
