Cytogenetics, flow cytometry, cytophotometry and morphometry of 22 cases of primary breast carcinoma. A comparative study.
1992
Cytogenetic, flow cytometric, cytophotometric and morphometric analyses were performed on 22 previously untreated, primary solid breast carcinomas. Although the cell nuclei as the primary object of these studies were the same in all the tumors, distinct features were evaluated in each case to determine to what degree the results obtained by these techniques are comparable. From the cytogenetic viewpoint, six tumors had a modal number in the diploid range, seven were in the triploid range, and two in the tetraploid range; seven tumors had no modal number. These data correlate with the flow cytometry and cytophotometry results obtained, with DNA values slightly higher than their respective ch…
Radial Scar Versus Tubular Carcinoma of the Breast
1995
Summary The present study is focused on the differential diagnosis between radial scar (RS) and tubular carcinoma (TC) using morphometrical and cytophotometrical analysis (static and flow cytometry) of a number of histologically well-established RS cases, (17 lesions) compared with 6 early infiltrating small TC with sclerotic stroma and pseudo-RS fields. One case displayed both RS and TC foci in contiguity. Mean nuclear area was larger in the group of tubular carcinomas (51.0 μ 2 ) than in the cases o f radial sclerosis (38.30 μ 2 ). We also found a larger number of aneuploid cases in tubular carcinomas measured by image cytometry, but both types o f lesions were diploid when measured by fl…
