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.

Positive
- Benign prostate.
- Prostate cancer.
- Some hindgut neuroendocrine tumours.[2]
Microscopic
Features:
- Cytoplasmic staining.
