What is severe cytologic atypia?

Severe cytologic atypia refers to significant abnormalities in the size, shape, and organization of cells observed under a microscope, indicating a high degree of deviation from normal cellular characteristics. This condition often suggests the potential for neoplastic changes, such as the presence of precancerous lesions or cancer. Severe cytologic atypia is commonly evaluated in various tissues, including cervical smears and biopsies, and typically necessitates further diagnostic investigation due to its association with malignancy.
