Isolated intracranial rosai-dorfman disease involving the meninges: report of a rare case.
Sinus histiocytosis with massive lymphadenopathy or Rosai-Dorfman disease (RDD) is a reactive condition of unknown etiology, characterised by a proliferation of histiocytes exhibiting emperipolesis of lymphocytes and plasma cells. It usually presents as bilateral painless cervical lymphadenopathy. Extranodal RDD without nodal disease is seen in 23% of the cases. Intracranial RDD occurs in less ...

Rosai-Dorfman disease (RDD) is a rare benign proliferative disorder of histiocytes in the lymph nodes with or without extranodal involvement. RDD limited to the skin without nodal involvement, known as cutaneous Rosai-Dorfman disease, is very rare. We describe a 34-year-old female with RDD of the skin over the chest. A large nodule with satellite lesions was excised for histopathological examin...

متن کاملFine-needle aspiration cytology of Rosai-Dorfman disease.
Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) is a rare, benign self-limiting condition of unknown etiology. Less than a quarter of cases have only extranodal involvement and a few cases of skeletal involvement of Rosai-Dorfman disease without associated lymphadenopathy have been reported in the literature. We herein report cytohistologic findings in a case of sole sk...
