This case study highlights a man diagnosed with polycythemia vera, a condition causing elevated red blood cells. Early diagnosis and treatment involving phlebotomy and medication are crucial for managing this blood disorder.
Area of Science:
- Hematology
- Internal Medicine
- Cardiology
Background:
- Polycythemia vera is a chronic myeloproliferative neoplasm characterized by excessive production of red blood cells.
- Erythrocytosis can lead to various complications, including thrombosis and cardiovascular events.
Observation:
- A male patient in his late 60s presented with itching and headache, exhibiting ruddy complexion and splenomegaly.
- Physical examination revealed normal left ventricular function but an apical left ventricular thrombus measuring 3.0 cm×2.0 cm.
Findings:
- Complete blood count showed significant erythrocytosis (Hemoglobin 18.1 g/dL, Hematocrit 56.6%).
- Low erythropoietin levels and the presence of the JAK2 V617F mutation confirmed the diagnosis of polycythemia vera.
- Transthoracic echocardiogram identified a large left ventricular apical thrombus.
Implications:
- This case underscores the importance of investigating erythrocytosis to rule out underlying conditions like polycythemia vera.
- The presence of a left ventricular thrombus in the context of polycythemia vera highlights the prothrombotic state associated with this disease.
- Prompt diagnosis and multi-modal treatment, including phlebotomy, aspirin, enoxaparin, and hydroxyurea, are essential for managing polycythemia vera and its complications.

Disorders of Erythrocytes
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.
