Estrogen receptor, abbreviated ER, is a common immunostain.
General
- Nuclear stain - like most other "p" stains.
- In the context of breast pathology it is a class II IHC test, as it is used for treatment decisions by itself.[1]
Positive
- Breast carcinoma - most.
- Ductal carcinoma in situ - most.
- Invasive lobular carcinoma - all.
- Invasive ductal carcinoma of the breast - most.
- Endometrial carcinomas.
Occasionally positive
- Lung adenocarcinoma - dependent on the ER subunit target - ERα ~1%, ERβ ~79%.[2]
Negative
