Diabetes insipidus as first manifestation of acute myeloid leukaemia with EVI-1-positive, 3q21q26 syndrome and T cell-line antigen expression: what is the EVI-1 gene role?
Two cases of acute myeloid leukaemia (AML) with CD2 and CD7 expression associated with diabetes insipidus (DI) as the initial symptom are presented. Both patients had t(3;3)(q21;q26) associated with monosomy 7 and EVI-1 overexpression. No neurohypophysis infiltration was evident. One patient died during induction chemotherapy, the other did not respond to therapy and died with persistent DI. Our findings further support the existence of a distinct AML entity characterized by the presence of DI, abnormalities of chromosome 3q, dysmegakaryopoiesis and poor outcome, and provide evidence of EVI-1 gene involvement. The possible role of chromosome 3q26 abnormalities in determining this peculiar clinical-biological association is emphasized.
