✦ Synopsis


Bone-marrow aspiration smears of 38 cases of acute leukemia (19 acute lymphoblastic leukemia, 19 acute nonlymphocytic leukemia) were stained for argyrophilic nucleolar organiser regions (AgNOR). AgNOR were assessed numerically and morphologically. There were highly significant differences in AgNOR morphology between acute lymphoblastic leukemia and acute nonlymphocytic leukemia ANLL: lymphoblast AgNORs were usually small (<3 Β΅m) "dots/chips," whereas myeloblasts showed larger "blebs," or a combination of the two types (complex structures). AgNOR number was significantly less in acute lymphoblastic leukemia. In acute nonlymphocytic leukemia cases, AgNOR number also showed direct correlation with Ki67 reactivity of leukemic blasts. Am.

A multiparameter analysis of 706 cases of acute leukemia (AL) over a two-year period revealed only six cases (0.86 per cent) with coexpression of lymphoid and myeloid phenotypes. In three cases, expression of both lymphoid and myeloid markers by the majority of the blast cells suggested a 'biphenoty

Abnormalities of chromosome band 13q14 occur in hematologic malignancies of all lineages and at all stages of differentiation. Unlike other chromosomal translocations, which are usually specific for a given lineage, the chromosomal translocation t(12;13)(p12;q14) has been observed in both B-cell and
