NORMAL:
Squamous cells with small blue nuclei and abundant pink/green
cytoplasm. A group of endocervical glandular cells can be seen in
the lower left corner with a "honeycomb" arrangement.

ASC-US:
Squamous cells with some nuclear enlargement but still abundant
cytoplasm.

LOW GRADE:
Squamous cells with enlarged dark blue nuclei, occasionally with a
cleared ring of cytoplasm.

HIGH GRADE:
Very enlarged blue nuclei with less abundant cytoplasm, resulting in
a high nuclear to cytoplasmic ratio.

SQUAMOUS CANCER:
Very enlarged nuclei with irregular distribution of nuclear material
and nucleoli (red clumps in nuclei); dense spindled pink/orange
cytoplasm.
