Brief summary
Rosai-Dorfman Disease (RDD) is a rare, heterogeneous histiocytic disorder. Because of the rarity of RDD and a lack of prospective randomized trials, the treatment strategy for RDD is mostly based on retrospective study. Steroid was suggested as frontline treatment as RDD with only lymph nodes involvement. Studies showed thalidomide or lenalidomide showed some effect in recurrent/refractory skin RDD. The investigators want to analyze the efficacy and toxicity of lenalidomide combined with dexamethasone regimens in the treatment of RDD among adult patients at our hospital.
