Intraepithelial lymphocytes, abbreviated IELs, is the presence of lymphocytes between (benign) epithelial cells. IELs are seen in a number of contexts.
Lymphocytic proctitis. H&E stain.
The epithelial cells in the context of IEL are presumed to be benign. Lymphocytes infiltrating between malignant (epithelial) cells is dealt with in the tumour infiltrating lymphocytes article.
Small bowel
- Celiac disease - classic cause.
- Giardia.
- Helicobacter gastritis.
- Crohn's disease.[citation needed]
- Morbid obesity.[1]
Large Bowel
- Lymphocytic colitis.[2]
- Collagenous colitis.[2]
- Celiac disease.[3]
- Crohn's disease.[4]
- Drug-induced colitis.[citation needed]
