Rosai-Dorfminan disease (RDD), or sinus histiocytosis with massive lymphadenopathy, is a benign idiopathic proliferative disorder of the histiocyte. Purely Cutaneous Rosai-Dorfman disease (CRDD) is a separated clinical entity without lymph node and organ involvement. The histologic features resemble RDD, but with dermal infiltration. This rare condition is benign and mostly self-limited The authors report a 66-year-old Thai male patient, diagnosed as purely CRDD, with co-existing capillary hemangioma. In addition, we show that the treatment intralesional corticosteroid can produce the remission of the plaque and tumoral types of this condition.
