Expanding diagnostic criteria: Multiorgan T-Cell/myeloid mixed phenotype acute leukemia with t(v;11q23) KMT2A-rearrangement successfully treated by allogeneic stem cell transplant
Mixed phenotype acute leukemia (MPAL) consists of a leukemia of two different lineages (myeloid, T, and/or B) co-occurring in the same tissue. KMT2A-rearrangement is rare and usually seen in B/myeloid MPAL. We report a unique case of T/myeloid MPAL with a t(v;11q23) KMT2A-rearrangement, with acute m...

description | Mixed phenotype acute leukemia (MPAL) consists of a leukemia of two different lineages (myeloid, T, and/or B) co-occurring in the same tissue. KMT2A-rearrangement is rare and usually seen in B/myeloid MPAL. We report a unique case of T/myeloid MPAL with a t(v;11q23) KMT2A-rearrangement, with acute myeloid leukemia (AML) in the bone marrow but concurrent T-cell acute lymphoblastic leukemia (T-ALL) in lymph node and skin. Genomic interrogation suggests an undifferentiated stem cells with KMT2A rearrangement as the founder mutation that acquired additional lineage-specific mutations resulting in AML in the marrow and T-ALL in other sites. |
