Objectives:
This work aims to describe the proportion of patients with polycythemia vera (PV) or essential thrombocythemia (ET) and thrombosis prior to the diagnosis who had erythrocytosis or thrombocytosis prior to the thrombosis.
Patients And Methods:
This is a retrospective review of 63 patients with PV and 130 with ET.
Results:
In regard to PV, we found prior erythrocytosis in 7 (11.1%) of the 17 cases (27%) with thrombosis prior to diagnosis. In ET, we found prior thrombocytosis in 10 (7.7%) of the 25 cases (19.2%) with thrombosis prior to diagnosis. The median time between the laboratory finding and thrombosis was 8.2 months and 11.8 months for PV and TE, respectively. In both entities, patients with thrombosis prior to diagnosis had significantly lower survival.
Conclusion:
A significant proportion of patients with thrombosis prior to the diagnosis of PV and ET present with erythrocytosis or thrombocytosis prior to the episode of thrombosis. This could allow for anticipating diagnosis and treatment.

Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
