Walthard cell rest, also Walthard cell nest, is a benign finding often seen in gynecologic pathology.
General
Epidemiology
- Thought to be related to Brenner tumour.

Features:[2]
- Collection of eosinophilic (i.e. pink) cuboidal cells; usually solid, may be cystic.
- Elliptical nucleus with single groove along major axis; "coffee bean" nucleus -- key feature.
Location:
- Usually in soft tissue of the uterine tube.
DDx:
- Brenner tumour - consist of (multiple) nests with a surrounding fibromatous stroma.[3]
