Citologia Cervicale
Squamous carcinoma of the cervix, cervical intraepithelial neoplasia (CIN) and atypical squamous cells of undetermined significance (ASCUS)
 
CIN 1 (mild dysplasia): Note undifferentiated cells occupy lower third of the epithelium after which they start to differentiate so that the epithelial cells in the upper two thirds appear to have more cytoplasm and smaller (but abnormal) nuclei. Mitoses are rare.
