Overview

Polycythemia vera must be differentiated from other myeloproliferative neoplasms, such as chronic myelogenous leukemia, essential thrombocythemia, and primary myelofibrosis. Polycythemia vera must also be differentiated from secondary polycythemia, which is usually due to chronic hypoxia. Each of these conditions have different etiologies, symptoms, laboratory abnormalities, physical exam findings, and treatments.

Differential Diagnosis

Polycythemia vera must be differentiated from a variety of other conditions.[1][2][3]

Disease Etiology Symptoms Signs Laboratory abnormalities Treatment Other associated abnormalities
Polycythemia vera (PV)
  • JAK2 mutation (V617F or exon 12 mutation) in more than 95% of cases
  • Autonomous erythrocyte production
Essential thrombocythemia (ET)
  • Clonal proliferation of megakaryocytes
  • Excess platelet production
  • Caused by JAK2 mutation in 50% of cases
  • Caused by CALR mutation in some cases
  • Paradoxical bleeding can occur when platelet count is above 1,000,000 cells/microliter due to acquired von Willebrand disease
  • Can progress to post-ET myelofibrosis
  • Can develop into acute leukemia
Chronic myeloid leukemia (CML)
  • Reciprocal translocation of chromosomes 9 and 22
  • Production of BCR-Abl kinase, which drives cell proliferation
Primary myelofibrosis (PMF)
Secondary polycythemia
  • Treatment of underlying cause of hypoxia
  • Supplemental oxygen
  • Diuresis for CHF
  • Steroids for ILD
  • Continuous positive airway pressure for OSA
  • Smoking cessation or nicotine replacement
  • Surgical removal of tumors
  • Variable manifestations given the diverse etiologies
