title: Morphometric Characterization of HPV-Related Lesions of Uterine Cervix.
abstract: OBJECTIVE
  This study addresses three issues related to human papillomavirus (HPV) cervical lesions: identification of HPV in histologic normal tissue, identification of HPV subtypes with risk for cervical cancer, and histologic differences between HPV not associated to cervical intraepithelial neoplasia (CIN1) lesions (condyloma) and HPV associated to CIN1 lesions.
  
  
  METHODS
  The authors histologically classified 48 cervical biopsy slides into three groups: normal (n = 22), condyloma (n = 20), and CIN1 (n = 6). Morphometric analyses of nuclear and cytoplasmic ratio for area, length, and diameter of 25 cells per case were performed. Histologic reports and in situ hybridization for HPV subtype were compared to morphometric data to assess correlation among them.
  
  
  RESULTS
  Using image analysis, the authors correctly classified all cases except two into histologic or in situ hybridization diagnosis. Morphometry helped identify viral changes in cells that appeared histologically normal, HPV subtype at risk in condyloma lesions, and condyloma from those combining HPV lesions and CIN1.
  
  
  CONCLUSIONS
  There were enough data supporting morphometric distinction of HPV-related cervical lesions assessed by nuclear and cytoplasmic ratio.
