The bone marrow is hypercellular due to a panmyelotic proliferation typically characterized by pleomorphic megakaryocytes. The major symptoms are related to hypertension, splenomegaly or to episodes of thrombosis and/or hemorrhage.

The number of white blood cells and platelets may also increase. The extra blood cells may collect in the spleen and cause it to become enlarged. They may also cause bleeding problems and make clots form in blood vessels.
