title: Ag-positive regions on unusual chromosome locations.
abstract: A 28-year-old woman with a 46,XX,t(13;21)(q14;p11) karyotype showed both chromosome unstability and an unusual Ag-positivity on her chromosomes. Since there are reports about affinity of the NORs for broken chromosome ends, the two different phenomena observed in the present case are probably related.
