<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">NMZL中仅<span style="color: black;">少许</span>病例可累及外周血,外周血涂片常表现为小至中等<span style="color: black;">体积</span>的中心细胞样<span style="color: black;">反常</span>淋巴细胞,可出现浆细胞分化或偶尔<span style="color: black;">显现</span>单核细胞样外观,但很少观察到粒细胞样改变。本例NMZL<span style="color: black;">病人</span>外周血<span style="color: black;">反常</span>淋巴细胞核呈粒细胞样外观,并<span style="color: black;">显现</span>“Pelger-Huët样”<span style="color: black;">反常</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Pelger-Huët<span style="color: black;">反常</span>是一种遗传性良性<span style="color: black;">疾患</span>,以中性粒细胞染色体分叶不良,<span style="color: black;">引起</span>双叶、花生样或哑铃形核为<span style="color: black;">重点</span>特征。该<span style="color: black;">反常</span>与维持核膜结构的层粘连蛋白B受体(LBR)基因突变<span style="color: black;">相关</span>。假性Pelger-Huët<span style="color: black;">反常</span><span style="color: black;">做为</span>粒细胞<span style="color: black;">生长</span>不良的标志物,仅与中性粒细胞<span style="color: black;">相关</span>,可见于骨髓增生<span style="color: black;">反常</span><span style="color: black;">综合症</span>和急慢性白血病中,<span style="color: black;">亦</span>可与<span style="color: black;">药品</span>诱导<span style="color: black;">相关</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">淋巴细胞的“Pelger-Huët样”<span style="color: black;">反常</span>是一种极为罕见的现象,在该类病例中为首次<span style="color: black;">报告</span>。与细胞核分叶不良<span style="color: black;">导致</span>的中性粒细胞Pelger-Huët<span style="color: black;">反常</span>相反,淋巴细胞“Pelger-Huët样”改变<span style="color: black;">是由于</span>细胞核<span style="color: black;">反常</span>分叶<span style="color: black;">导致</span>的。</p>
