Normalized nuclear area of GAS, UEA, and benign endocervical cells. GAS cells contain nuclei of approximately twice the area of a neutrophil or a benign endocervical cell. The normalized nuclear areas of both GAS and UEA are similar and significantly different from benign endocervical cells. GAS, gastric-type endocervical adenocarcinoma; UEA, usual-type endocervical adenocarcinoma; NILM, negative for intraepithelial lesion and malignancy (benign endocervical cells).
