Correlative study of human papillomavirus DNA, histopathology and morphometry in cervical condyloma and intraepithelial neoplasia.

This study includes 28 intraepithelial squamous lesions of the cervix associated with human papillomavirus (HPV) DNA sequences detected by the Southern blot technique. Objective analyses of the histologic features by morphometric parameters and mitotic index have demonstrated that lesions of HPV types 6 and 11 can be distinguished from types 16, 18, and 33 by stepwise discriminant functions. The latter lesions have higher mitotic and cellularity indexes and greater nuclear atypia than the former, supporting a greater degree of epithelial proliferation and abnormality seen in association with HPV types 16/18/33.
