Rosai-Dorfman Disease of the Central Nervous System

چکیده
Rosai-Dorfman disease (RDD) is an idiopathic, non-neoplastic, lymphoproliferative disorder characterized by sinus histiocytosis and massive lymphadenopathy. When RDD involves the central nervous system the lesion simulates a meningioma. Histological and immunohistochemical confirmation is essential for a definitive diagnosis. In this paper, ten cases of RDD confined to the central nervous system are reported. Another case with orbital RDD was excluded. Nine cases involved the cranial cavity alone; in one, the cervical extradural region was also involved. Treatment consisted of surgical excision or biopsy. Histology and immunohistochemistry revealed a mixed cell population of predominantly mature histiocytes with evidence of emperipolesis and strong positivity for S100 protein in all cases. No recurrence was observed during follow up ranging from three months to eight years.

Rosai-Dorfman disease or sinus histiocytosis with massive lymphadenopathy is a rare disorder that typically manifests as lymphadenopathy and systemic symptoms whose etiology remains poorly elucidated. The diagnosis is based on immunohistochemistry. Its treatment is poorly defined but the prognosis is usually favorable. Here we report a 14 year old boy who presented with massive bilateral cervi...

Sinus histiocytosis with massive lymphadenopathy (SHML) was first described in 1969 by Rosai and Dorfman [1]. It is a rare inflammatory disorder with key clinicopathological characteristics such as emperipolesis and positive immunostaining for S-100 protein [2] and CD68. Rosai–Dorfman disease (RDD) is primarily manifested in the lymph nodes, yet extranodal disease has been reported in as many a...

Rosai-Dorfman disease (RDD) is a rare idiopathic and lymphoproliferative disorder. Central nervous system (CNS) involvement is infrequent and typically manifests as an isolated lesion. In this article, we describe an unusual case of RDD with multiple lesions in the CNS, upper respiratory tract and lymph nodes. A literature review revealed 45 cases (including the one described herein) of systemi...

Any patient with bilateral lymphadenopathy especially in Indian subcontinent is regarded as suffering from tuberculosis unless proved otherwise. This sometimes leads to unwarranted delay in correct diagnosis and management if there is ignorance regarding other rarer etiologies. Rosai-Dorfman Disease (RDD) may present in the same manner and should always be kept on the back of the mind to help a...

UNLABELLED Rosai-Dorfman Syndrome (RDD) is a rare, benign, self-limiting disorder which is characterized by the non-malignant proliferation of distinctive histiocytic cell within lymphatic system. RDD has been described as a dynamic entity in the spectrum of histiocytosis with non-Langerhans cell histiocytosis at one end and Langerhans cell histiocytosis at the other. The exact etiology of this...
