Uterine cervix with atrophic changes
Diagnosis in short

Atrophic cervix. H&E stain.
LM small squamous cells with grey/blue cytoplasm, no "dancing"/"sparkling" chromatin, no mitoses
LM DDx HSIL, immature squamous metaplasia
IHC p16 -ve, Ki-67 rare basal cells
Site uterine cervix - exocervix
Clinical history usually postmenopausal
Prevalence common
Prognosis benign
Other normal - postmenopausal

Uterine cervix with atrophic changes is relatively common and is important to recognize as it can mimic HSIL.

It is also known as atrophy of the uterine cervix, cervical atrophy, atrophy of the cervix and cervix with atrophic changes.

General

  • Common.
  • Post-menupausal.
  • Important to recognize and differentiate from HSIL.

Microscopic

Features - squamous cells:

  • Cells smaller.
  • Cytoplasm grey/blue.
  • No "dancing"/"sparkling" chromatin.
  • No mitoses.

Notes:

  • Mitosis do not exclude the diagnosis.... but should make one think HSIL.

Features:[1]

UTERINE CERVIX, BIOPSY:
- SQUAMOUS MUCOSA WITH ATROPHIC CHANGES.
- BENIGN ENDOCERVICAL EPITHELIUM.
- NEGATIVE FOR DYSPLASIA.

COMMENT:
A p16 immunostain is negative. A Ki-67 immunostain marks rare basal cells.
