T-cell large granular lymphocytic leukemia and hereditary hemochromatosis: a fortuitous association?
We describe a patient with hereditary hemochromatosis (homozygous for C282Y mutation) and neutropenia who was found to have underlying T-cell large granular lymphocytic (T-LGL) leukemia. The diagnosis was confirmed by demonstrating T-cell receptor (TCR) gene rearrangement by polymerase chain reaction (PCR). Multiple quantitative and qualitative defects have been described for the T cells of patients with hemochromatosis. Although the association between the two may be fortuitous, this case report raises the possibility that the T cells in these patients may be susceptible to leukemic transformation as well.
