Cervical carcinomas with a micropapillary component: a clinicopathological study of eight cases.

Usual-type (HPV-related) cervical carcinomas may show micropapillary differentiation, usually as a focal finding, and the cells show reverse polarity like similar tumours arising in other sites. Micropapillary cervical carcinoma appears to be a clinically aggressive malignancy, although this needs to be confirmed in larger studies.
