Abstract
We report the first patient to develop ALL with a fusion gene of the erythropoietin receptor (EPOR) with immunoglobulin heavy chain (IgH) 22 years after a diagnosis of secondary erythrocytosis with unknown etiology. The IgH-EPOR rearrangement is known to induce increased expression of EPOR, and activates EPO-associated signal pathways by exogenous EPO stimulation, resulting in the increased proliferation and survival of IgH-EPOR-positive leukemic cells. Interestingly, this case may provide supporting the possibility that IgH-EPOR-positive ALL has a growth advantage under sustained high concentrations of EPO.Entities:
