Acute mixed-lineage leukaemia involving myeloid and T-cell phenotypes. A case report.

Among the rare acute mixed-lineage leukaemias, a myeloid T-cell phenotype has recently been recognised. An additional case characterised by myeloid cytochemistry, development of Auer rods in culture and Tdt, WT1 and T11 phenotypes on cell-marker analysis is reported. The patient died from disseminated non-reactive tuberculosis after chemotherapy.
