title: Analytical study of repair cells.
abstract: To establish the differential diagnosis of repair cells from malignant cells, 624 repair cells from 11 cases, 547 cells derived from 8 adenocarcinomas and 593 cells from 8 squamous-cell carcinomas were analyzed, with stress on the morphology of the nucleoli. Such planimetric data as mean cellular areas, mean nuclear areas, mean nucleolar areas, nuclear-cytoplasmic ratios and nucleolar-nuclear ratios were fairly similar among the three cell groups. However, the even distribution of nucleoli in the nuclei, the decrease in C-type nucleoli and nucleoli consistently linked with nucleolus-associated chromatin were noted to be reliable criteria for the diagnosis of repair cells along with such well-known morphologic characteristics as the sheetlike arrangement of repair cells, the lack of isolated forms, the finely granular chromatin pattern and the round, smooth nuclear configuration with a thin nuclear membrane.
