登革热是一种由蚊子传播的传染病，在全球 100 多个国家流行。在登革热可引起的并发症中，噬血细胞性淋巴组织细胞增多症因其严重性和复杂的诊断而备受关注。在此，我们记录了一名先前健康的 6 岁女性患者的这种疾病病例，她的登革热感染非常严重，需要住院治疗。使用血管活性药物和利尿剂进行重症监护管理。短期后，病情又开始好转，出现发烧、全血细胞减少、肝炎和炎症反应症状。怀疑患有登革热相关噬血细胞性淋巴组织细胞增多症综合征，并接受静脉注射皮质类固醇治疗，为期 3 天，没有出现恶性肿瘤迹象，反应良好。医疗保健专业人员必须了解这种不新鲜的实体，以便在大多数情况下实现有效的诊断和治疗，但不仅如此，登革热病毒在热带和亚热带地区流行。知识共享 Reconocimiento-NoComercial 4.0 国际。
