Prostatic specific acid phosphatase, abbreviated PSAP, is prostate marker that predated prostate-specific antigen (PSA).
It is also known as prostatic acid phosphatase, abbreviated PAP.
General
- Cannot differentiate between benign prostate and prostate cancer, like PSA.[1]
Positive
- Benign prostate.
- Prostate cancer.
- Some hindgut neuroendocrine tumours.[2][3]
Microscopic
Features:
- Cytoplasmic staining.
Images
PSAP - intermed. mag.
PSAP - high mag.
