Seema Dawood: When Elevated Platelets Signal a Myeloproliferative Neoplasm

Seema Dawood, Medical Laboratory Technologist at The Aga Khan University Hospital, shared a post on LinkedIn:

“Essential Thrombocythemia (ET)

A myeloproliferative neoplasm (MPN) characterized by excessive platelet production in the bone marrow, resulting in persistent thrombocytosis.

Key Features of ET Platelet count – 450,000/µL

  • Frequently – 1,000,000/µL
  • Giant / Large Platelets are commonly seen
  • Platelet anisocytosis may be present
  • RBC and WBC morphology are usually normal

Major Complications

  • Thrombosis
  • Hemorrhage, even in patients with extremely high platelet counts

ET Differs from Other Conditions

  • Giant platelets are more prominent in Essential Thrombocythemia than in Myelo dysplastic Syndrome (MDS)
  • Unlike Reactive Thrombocytosis, ET is a primary bone marrow disorder.”
