Introduction: Although The Bethesda System for Reporting Cervical Cytopathology does not mandate reporting of endocervical glandular involvement (EGI) in Papanicolaou test specimens with high-grade squamous intraepithelial lesions (HSIL), several studies have suggested that EGI diagnosed on surgical specimens is associated with higher rates of residual or recurrent dysplasia. When suspected, EGI is reported for Papanicolaou test specimens at our institution, but the performance of this diagnosis has not been assessed.
Materials And Methods: The archives were queried for Papanicolaou test specimens with a diagnosis of HSIL-EGI (2006-2017).
