    Description / Table of Contents: Zusammenfassung Bei zwei Patienten fiel im EDTA-Blutausstrich eine außergewöhnliche Adhärenz von Blutplättchen an Granulocyten auf. In den gleichen Blutproben wurden verminderte Thrombocytenwerte gezählt. Diese Granulocyten-Plättchen-Rosetten treten sehr selten, nur in vitro im EDTA-Blut und an neutrophilen Granulocyten auf. Eine Plättchenphagocytose durch Granulocyten konnte nachgewiesen werden. Die auslösende Ursache ist unbekannt. Zur Vermeidung eines falschen Thrombocytopenie-Befundes sollte bei Beobachtung von Granulocyten-Plättchen-Rosetten eine Kontrolle der Thrombocytenzahl im Capillarblut herangezogen werden.
    Notes: Summary Extraordinary platelet adherence to polymorphonuclear leukocytes was seen in EDTA anticoagulated blood smears of two patients. From the same blood samples platelets were greatly reduced in number. Platelet satellitism (granulocyte platelet rosettes) is a rare phenomenon in vitro, only seen in EDTA anticoagulated blood, and the platelets surrounded polymorphonuclear leukocytes only. Phagocytosis of platelets was also observed. The cause of platelet satellitism is unknown. Capillary blood should be investigated in order to prevent a false thrombocytopenia.
