Dural-based Rosai-Dorfman disease: differential diagnostic considerations.
Extranodal sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) is a non-neoplastic condition that has rarely been reported to involve the central nervous system. This report documents a 28-year-old man with Rosai-Dorfman disease who presented with a seizure and a dural-based mass that was thought to represent a meningioma. ⋯ Emperipolesis with intracytoplasmic lymphocytes and plasma cells was present. Differential diagnostic considerations will be discussed.
