Comprehensiveness

On this resource, the following formatting is used for comprehensiveness:

  • Minimal depth
  • (Moderate depth)
  • ((Comprehensive))

Fixation

Generally 10% neutral buffered formalin.

  See also: General notes on fixation


Microscopic evaluation

The main objectives are:

  • Making a diagnosis of endometrioid polyp. An endometrial polyp may be diagnosed in the presence of 2 of the following 3:
  • Thick-walled vessels
  • Collagenous stroma
  • Epithelium on at least 3 sides
  • Look for signs of atypia or malignancy.

Reporting

Most importantly:

  • Benign versus malignant (or presence or absence of atypia.)
  • ((The size of the polyp.))
  • ((The type of epithelium at both the surface and gland coverings.))

Example of a minimal report:

Benign endometrial polyp.
