Association of Polycythemia Vera With Positive JAK2V617F Mutation and Myasthenia Gravis: A Report of Two Cases

Abstract

1.7% of myeloproliferative neoplasms are associated with autoimmune conditions. Association of myasthenia gravis (MG) with chronic myeloid leukemia is reported, but its association with polycythemia vera (PV) has never been reported. We report two patients who had MG and PV with JAK2V617F mutation. Both had splenomegaly but no thymoma.
