Androgen receptor, abbreviated AR, is receptor activated by androgens (testosterone, dihydrotestosterone).
| Androgen receptor | |
|---|---|
| Immunostain in short | |
| Normal staining pattern | nuclear |
| Positive | salivary duct carcinoma, Brenner tumour, apocrine carcinoma of the breast, prostate carcinoma (most cases) |
Tumours with AR
- Salivary duct carcinoma +ve ~90% of cases.[1]
- Ovarian Brenner tumour.[2]
- Apocrine carcinoma of the breast - usu. smaller tumours.[3]
- Prostate carcinoma with amphicrine features.[4]
