چکیده
platelet adherence surrounding leucocytes in a rosette formation or platelet satellitism is a rare phenomenon. this finding has been observed almost exclusively in ethylenediaminetetraacetic acid treated blood at room temperature. the mechanism underlying this phenomenon is not fully understood. in many reports of platelet satellitism platelets clump to polymorphonuclear neutrophils in healthy persons undergoing routine checkup, and sometimes this phenomenon could be a reason for spurious thrombocytopenia. herein, we report a case of platelet rosetting around monocytes in a patient who was admitted with acute hemolysis due to g6pd deficiency with normal platelet count. keywords: platelet satellitism, monocyte, g6pd deficiency.
