Beyond the Surface: Diagnostic Significance of Parabasal Cells in Cervical Cytology

Parabasal cells, typically observed in postmenopausal cervical smears, are often overlooked in cytological evaluation. However, their presence in reproductive-aged women is an atypical finding that may indicate hypoestrogenism, epithelial trauma, or underlying endocrine dysfunction. These cells, due to their high nuclear-to-cytoplasmic ratio, can mimic high-grade squamous intraepithelial lesions, leading to diagnostic dilemmas and potential overtreatment. This short communication underscores the importance of recognizing the clinical relevance of parabasal cells, advocating for detailed clinical correlation and appropriate investigations. Accurate interpretation is essential to avoid misdiagnosis and to identify potentially reversible hormonal or systemic abnormalities.
