NEJM:母细胞浆细胞样树突状细胞瘤-病例报道

2020-11-26 MedSci原创 MedSci原创

母细胞浆细胞样树突状细胞肿瘤是一种全身性疾病,尽管它可以表现为皮肤病变。在治疗开始之前,包括使用糖皮质激素,获得完整的分期评估非常重要。

患者为一名29岁的男子,因进展性无痛、无瘙痒性皮肤病变6个月而到血液科就诊。他没有全身症状,例如盗汗或体重减轻。

体格检查显示面部、背部、躯干和四肢有广泛的冰冻样病变(如图A所示)。皮肤活检显示真皮浸润扩散,胚泡样细胞延伸至皮下。免疫组织化学分析发现,CD4、CD56和CD123阳性的细胞,支持诊断为罕见的血液系统癌性浆细胞样树突状细胞瘤。计算机断层扫描未发现皮肤外病变的证据。骨髓抽吸发现存在1%的肿瘤浆细胞样树突状细胞。

患者接受了疗程1周的地塞米松治疗,皮肤病变明显减轻(如图B所示)。然后用高剂量甲氨蝶呤和阿糖胞苷交替治疗,联合八个周期的高剂量CVAD(环磷酰胺、长春新碱、阿霉素和地塞米松)治疗,此治疗后病变完全缓解。

母细胞浆细胞样树突状细胞肿瘤是一种全身性疾病,尽管它可以表现为皮肤病变。在治疗开始之前,包括使用糖皮质激素,获得完整的分期评估非常重要。患者在治愈6个月后,疾病复发,并且患者对进一步治疗没有反应。他在诊断后27个月死亡。

NEJM:Tagraxofusp在浆细胞样树突状细胞肿瘤中的作用

由此可见,在未治疗或复发的BPDCN的成人患者中,使用tagraxofusp治疗具有临床反应。包括毛细血管渗漏综合征、肝功能障碍和血小板减少症在内的严重不良事件很常见。
