title: [Ag-NORS and non-pigmented tumors of the sclerocorneal limbus. Apropos of 20 cases].
abstract: We studied nucleolar organizers (Ag-NORS) in 20 cases of ocular limbic tumours of which 7 were Bowen disease or intraepithelial carcinoma and 13 were invasive carcinomas. The NOR-Index, reflecting cellular activity, increased from intraepithelial carcinoma (3.97) to microinvasive (5.45) and invasive carcinoma (5.81). Results of Nor-Index, reflecting proliferation, was in agreement with other technics such as immuno-labelling with Ki67 and PCNA antibodies.
