Cutaneous Rosai-Dorfman disease presenting as pustular and acneiform lesions.

We report 2 cases of cutaneous Rosai-Dorfman disease (CRD) presenting with pustular and acneiform lesions. To our knowledge, these are the first reports of CRD presenting in this pattern. One patient had spontaneous resolution of the lesions, whereas the other was treated with cryotherapy with clinical improvement. We present a review of the literature regarding CRD and highlight the benign nature of this condition.
