Cytological features of human papillomavirus-infected immature squamous metaplastic cells from cervical intraepithelial neoplasia grade 2. | LitMetric

AI Article Synopsis

  • The study focuses on reflex cytology, particularly the role of prominent nucleoli in immature metaplastic squamous cells (IM), which may be misinterpreted in diagnoses.
  • Researchers aimed to identify human papillomaviruses (HPVs) in IM clusters found in cervical intraepithelial neoplasia 2 (CIN2) using Pap smears from 32 patients.
  • Findings showed that HPV-positive IM clusters had a significantly larger median nuclear area compared to HPV-negative clusters, suggesting that certain nuclear characteristics can indicate the presence of neoplastic cells linked to HPV.

Article Abstract

In reflex cytology, the presence of prominent nucleoli in immature metaplastic squamous cells (IM) may be underdiagnosed due to variations in interpretation. The aim of this study is to identify human papillomaviruses (HPVs) that infect IM clusters in cervical intraepithelial neoplasia 2 (CIN2) on Papanicolaou (Pap) smears to determine the cytological features of lesion-derived cells. Thirty-two patients with a simultaneous diagnosis of CIN2 on biopsy and high-grade squamous intraepithelial lesions (HSIL) on cytology as well as with IM clusters on HSIL smears were included. CIN2 tissues and HSIL and IM clusters on Pap smears were isolated by manual microdissection, and HPV types were identified by PCR-based genotyping. The nuclear area within the IM clusters was also measured. The median nuclear area of HPV-negative IM clusters was 48 μm , with a coefficient of variation (CV) of 0.20; those of HPV-positive clusters were 66 μm and 0.34, respectively. The cut-off values of the nuclear area and CV for HPV positivity were 62 μm and 0.25, respectively. IM clusters composed of cells with a nuclear area of more than twice that of neutrophils or cells with a wide variation in nuclear sizes are likely to be neoplastic cells caused by HPV.
