Dyskaryosis in cervical cells. Light micrograph of squamous epithelial cells from a cervical smear showing mild dyskaryosis corresponding to cervical intraepithelial neoplasia (CIN) 1. The epithelial cells (blue and pink) make up the outer wall of the cervix, the passage linking the uterus to the vagina. Dyskaryosis is abnormality in the cell nucleus. Here, the cell nuclei have become enlarged and prominent (black, round), a sign of abnormal cell division. Cervical smears are examined to alert a doctor to the cellular changes associated with the development of cervical infection or cancer. Papanicolaou stained. Magnification: x400 at 35mm size.
