May Hegglin anomaly

May Hegglin's anomaly, as it is also known, is a rare genetic disorder of the blood platelets that causes them to be abnormally large. Also, this anomaly causes abnormalities in the white blood cells known as leukocytes.

Presentation
In the leukocytes, the presence of very small rods (around 3 micrometers), or Dohle bodies can be seen in the cytoplasm.

Treatment
In many cases, May Hegglin's requires no treatment. However, in extreme cases, blood platelet transfusions may be necessary

Causes
An association with MYH9 has been described.
