title: Nuclear DNA content distribution in five parotid gland tumors. A preliminary report.
abstract: Quantitative cytophotometric evaluations of nuclear DNA content were made on epithelial cells obtained from five cases of parotid gland tumors. The measurements were performed on sections stained with Feulgen reaction and, as control of diploid value, adventitious small lymphocytes as well as normal epithelial cells were considered. A fairly good correlation between the type of histogram of DNA values and a progressive degree of atypia was found since particularly high levels of hyperdiploidy were found in more severe tumors.
