The histopathological distinction was statistically examined between an endometrial adenomatous hyperplasia (aH) and a well differentiated type of invasive endometrial adenocarcinoma (wC). The significant morphometric indices were disclosed as follows: (1) indices related to a structural atypism, based on the index of glandular area per unit area (IGA), the index of cellular area per unit area (ICA), and the index of gland-in-gland configuration per unit area (IGG), which were higher in the wC with the significant levels of 0.001, 0.001, and 0.02, respectively (t-test); (2) indices related to a cellular atypism, being made up of the mean nuclear long axial diameter (NLAD), the mean nuclear short axial diameter (NSAD), the mean nuclear area (NA), and the mean nucleolar maximal diameter (nMD), which were larger in the wC with the statistical significances of 0.1, 0.02, 0.05, and 0.05, respectively (t-test); and (3) the mean age of the wC was older than that of the aH with the significance of 0.001 (t-test). Furthermore, the multivariate analysis with the use of these reliable indices led five perfect linear discriminants. It is concluded that the multivariate analysis is valuable for the histopathological distinction between the wC and the aH.
