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