Cytophotometric study of DNA content of cells in type III cervical smears

Cytophotometric study of suspicious (group III of the Papanicolaou's classification) smears shows the heterogeneity of this group, which includes cases with diploid--tetraploid DNA modes, cases with a wide distribution of DNA values and aneuploid cases. The significance of these findings in relation with the biological properties of cells is briefly discussed.
