Walthard cell rest
Diagnosis in short

A cystic Walthard cell rest of the fallopian tube. H&E stain.

LM collection of eosinophilic (i.e. pink) cuboidal cells - usually solid, may be cystic; elliptical nucleus with single groove along major axis - "coffee bean" nucleus
LM DDx Brenner tumour
Site Fallopian tube, testis

Syndromes none

Signs none
Prevalence common
Prognosis benign
Treatment none

Walthard cell rest, also Walthard cell nest, is a benign finding often seen in gynecologic pathology.

General

  • Benign.
  • Typically an incidental finding.
  • May be found in the testis.[1]

Epidemiology

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]
