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

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

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

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.
