Abstract
目的: 探讨慢性中性粒细胞白血病累及皮肤的临床病理学特点。 方法: 收集1例慢性中性粒细胞白血病患者的临床资料,描述其皮肤斑块的大体和镜下形态学特点、聚合酶链反应(PCR)法检测集落刺激因子3受体T618I突变情况。 结果: 本例为62岁男性患者,反复白细胞升高5年,骨髓及血细胞形态学检查显示以中、晚、杆状、分叶核粒细胞为主,BCR-ABL融合基因为阴性。晚期出现皮肤斑块和皮疹。镜下见真皮内大量成熟分叶核中性粒细胞浸润伴核碎裂,未见围皮肤附件分布表现,未侵犯毛囊、皮脂腺等皮肤附件。皮肤标本检测到集落刺激因子3受体T618I突变,进一步证实这些貌似正常的中性粒细胞为肿瘤性病变。 结论: 慢性中性粒细胞白血病极其罕见,多在血液科诊断,本例因病变累及皮肤而偶然为病理医师所见,在临床病史不明的情况下极易漏诊、误诊,希望能引起病理医师的关注和重视。.
