[Platelet satellitosis]

Platelet satellitism (PS) is a rare phenomenon described sporadically in the literature. It involves adhesion of thrombocytes sensitized by antibodies to leucocytes and is observed in vitro in EDTA anticoagulated blood. The authors' contribution to the problem is the observation of special thrombocyte aggregates surrounding neutrophils resembling comet tails, as well as the fact that the authors observed the formation of aggregates surrounding also lymphocytes and eosinophil cells.
