Polycythemia: P. vera is a primary proliferation of certain bone marrow cells resulting in elevations of the platelet count in the blood. It is considered a pre-neoplastic disorder and merits watching, a bone marrow biopsy perhaps and possible cytogenetic tests. Secondary thrombocythemia is a "reactive" elevation of the platelet count, such as due to anemia, with no malignant potential.
