LEEP cone biopsy displaying normal cervical epithelium (far left) progressing to borderline koilocytosis, to LSIL, and to HSIL (far right). A squamous intraepithelial lesion (SIL) is an abnormal growth of epithelial cells on the surface of the cervix, commonly called squamous cells.
ThinPrep pap smear with group of normal cervical cells on left and HPV-infected cells showing features typical of koilocytes: enlarged (x2 or x3) nuclei and hyperchromasia. A koilocyte is a squamous epithelial cell that has undergone a number of structural changes, which occur as a result of infection of the cell by human papillomavirus (HPV ...

The cause of CIN is chronic infection of the cervix with HPV, especially infection with high-risk HPV types 16 or 18.
