The polymorphonuclear leukocyte to the left is surrounded by similar platelets. The peripheral blood phenomenon illustrated here is called platelet satellitism. The red blood cells in the picture show some mild variability in size but all are well-hemoglobinized. This may result in spurious throbmocytopenia. The phenomenon shown here is platelet satellitism.
Platelets form a wreath around a segmented neutrophil.
The platelets themselves exhibit normal size and granularity. By definition, at least four platelets must adhere to the cell. Typically, segmented neutrophils and bands are involved, but very rarely monocytes may also exhibit satellitosis. All the leukocytes are segmented neutrophils. They are surrounded by platelet wreaths.
