Nucleolar organizer regions (NORs) and myoepitheliomas: a comparison with DNA content and clinical course

J Laryngol Otol. 1992 Jul;106(7):616-20. doi: 10.1017/s0022215100120341.

Abstract

Nucleolar organizer regions (NOR) were studied in 15 salivary gland myoepitheliomas by an argyrophilic staining technic (AgNOR). The AgNOR data were then compared with flow cytometric DNA content of the neoplasms and also with selected clinicopathologic parameters. We conclude that AgNOR's: (1) do not correlate well with DNA cytometric indices and (2) at best, provide redundant information.
