Abstract

Satellitism of platelets to monocytes was observed in 3 patients suffering from polycythaemia vera, a myeloproliferative disorder and chronic lymphocytic leukaemia. This phenomenon occurred on cells in the buffy coat obtained from venous blood anticoagulated with heparin. The existence of platelet satellitism was reported to occur mainly to polymorphonuclears, but the present observation, as well as a previous report from our department, indicated that it may also exist to monocytes. Satellitism was achieved either by adherence of the platelets to monocytes, giving the impression of rosette formation, or by fusion of platelet pseudopodia with the monocyte membrane. The importance of this phenomenon in the evaluation of the platelet count using automatic instruments is discussed.

摘要

在3例真性红细胞增多症（一种骨髓增殖性疾病）和慢性淋巴细胞白血病患者中观察到血小板对单核细胞的卫星现象。这种现象发生在用肝素抗凝的静脉血中获得的血沉棕黄层细胞上。据报道，血小板卫星现象主要发生在多形核细胞上，但本观察以及我们科室之前的一份报告表明，它也可能存在于单核细胞上。卫星现象是通过血小板黏附于单核细胞，形成玫瑰花结样外观，或者通过血小板伪足与单核细胞膜融合来实现的。本文讨论了这种现象在使用自动仪器评估血小板计数中的重要性。
