Rosai–Dorfman disease (RDD), or Sinus Histiocytosis with Massive Lymphadenopathy (SHML) is a self-limiting, rare benign proliferative disorder of histiocytes in the lymph nodes with occasional extra-nodal involvement of the skin. Isolated Cutaneous Rosai-Dorfman disease(C-RDD) without node involvement is an exceedingly rare occurrence. Despite its unique characteristics, the diagnosis of Cutaneous Rosai Dorfman disease is hampered by its variable clinical presentation, misleading histopathological patterns, and the absence of lymphadenopathy. Herein we present a case report of Cutaneous Rosai-Dorfman disease without any lymph node involvement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
