|---|---|
| Immunostain in short | |
 CDX2 immunostaining in the papillary thyroid carcinoma cribriform morular variant. | |
| Abbreviation | CDX2 |
| Normal staining pattern | nuclear |

| Negative | lung adenocarcinoma |
CDX2 is a commonly used immunostain in pathology. It is a nuclear stain.
Normal
Pathology
Positive
- Intestinal adenocarcinomas.
- Colorectal adenocarcinoma ~ 90% of cases.[2]
Sometimes positive
- Stomach adenocarcinoma ~20-30% of cases.[2]
- Esophageal adenocarcinoma ~20-30% of cases.[2]
- Ovarian mucinous adenocarcinoma[1] ~20-30% of cases.[2]
- Endometrioid endometrial adenocarcinoma ~20-30% of cases.[2]
- Yolk sac tumour (8 +ve of 20 cases[3]).
- Small bowel adenocarcinoma +ve/-ve (~43% +ve in series of 189 cases[4]).
Negative
- Lung adenocarcinoma -ve.
- Choroid plexus papillomas -ve (0 in 65 cases[7]).
- Pituitary adenoma & Craniopharyngioma (0 in 75 and 0 in 23 cases [8]).
