Presentations
Cervical dysplasia specimens may present as:
Dysplasia grading
Dysplasia is mainly seen as nuclei with hyperchromasia, coarse chromatin and irregular contours.[1]
Histology Grade | Corresponding Cytology | Description | Image |
---|---|---|---|
CIN 1 (Grade I) | Low-grade squamous intraepithelial lesion (LSIL) |
|
|
CIN 2/3 | High-grade squamous intraepithelial lesion (HSIL)[notes 1] |
|
|
CIN 2 (Grade II)[notes 2] |
|
||
CIN 3 (Grade III)[notes 3] |
|
Spectrum from normal to high grade SIL.[2]
Endocervical gland invasion is associated with high-grade lesions.[3]
Radicality
Look whether there is normal epithelium on each side of all slices where neoplasia is seen, and when the epithelium is missing in any direction, consider ordering additional serial sections or step sections.
HPV changes
Also look koilocytic changes of human papillomavirus (HPV), with such cells typically displaying:
- Nuclear enlargement (two to three times normal size).
- Irregularity of the nuclear membrane contour, creating a wrinkled or raisinoid appearance.
- A darker than normal staining pattern in the nucleus, known as hyperchromasia.
- Perinuclear cytoplasmic vacuolization ("nuclear halo").
Microscopy report
If a neoplasia is found, the report should include:[4]
- The histolopathological type and degree of differentiation
- Location and extent
- Radicality
