Intracranial recurrences of Rosai-Dorfman disease in the sellar region: two illustrative cases.
2011
Rosai–Dorfman disease [RDD] is a condition of an unknown etiology, characterized by proliferation of histiocytes. Not uncommonly extranodal lesions occur, but sellar involvement is very rare. Treatment of this lesion is complicated, especially in cases of recurrences at multiple intracranial sites. We report two cases of RDD in the sellar region with intracranial recurrences to illustrate the clinicopathological features and considerations of the optimal management.
