Rosai-Dorfman病(Rosai-Dorfman disease, RDD)是一种原因不明、少见的良性组织细胞增生性疾病,主要表现为无痛性双侧颈部淋巴结肿大,少数可发生在淋巴结外组织。由于RDD没有特征性临床及影像学表现,因此容易被误诊。迄今,该病尚无统一的治疗意见,多数预后良好。本文报道一例韦氏环及鼻腔RDD,分享放疗治疗RDD的经验,并借此讨论韦氏环淋巴结肿大的鉴别诊断。Rosai-Dorfmandisease is a rare unknown proliferative disease of the benign tissue cell, witha main symptom of painless bilateral cervical lymph node enlargement, and feweroccurrences may be diagnosed in peripheral lymph nodes. Since Rosai-Dorfmandisease displays no characteristic clinical and imaging features, it is moreliable to be misdiagnosed. There is not a unified treatment of the disease sofar; however, the prognosis of most of the patients is good.
