Platelet Satellitism: A Cause of Pseudothrombocytopenia

What is platelet satellitism in a blood smear? The mechanism of platelet adhesion to neutrophils in vitro, and false thrombocytopenia on a hematology analyzer.

Platelet satellitism is a phenomenon in which platelets accumulate around leukocytes, especially neutrophils, in blood smears. The phenomenon is usually observed in vitro and can mimic thrombocytopenia during automated counting. A very rare phenomenon!
