What is the definition of Rosai-Dorfman Disease?
Rosai-Dorfman disease was first described by Rosai and Dorfman in 1969. It is a benign disease which is characterized by over-production and accumulation of a specific type of white blood cell (histiocyte) in the lymph nodes of the body, most often those of the neck (cervical). Other lymph node groups may also be involved and, in some cases, abnormal accumulation of histiocytes may occur in other areas of the body (extranodal). The cause of this condition remains unknown, although altered immune responses and infectious agents may play a role. Rosai-Dorfman disease is a self-limited and seldom life-threatening disease which commonly does not require therapy.
What are the alternative names for Rosai-Dorfman Disease?
- Sinus histiocytosis with massive lymphadenopathy
- Rosaï-Dorfman disease
What are the causes for Rosai-Dorfman Disease?
The exact cause of Rosai-Dorfman disease is unknown. Possible causes include altered immune responses and infections by agents such as varicella-zoster and other herpetic viruses; Epstein-Barr; cytomegalovirus; Brucella; and Klebsiella.
What are the symptoms for Rosai-Dorfman Disease?
The symptoms and physical findings associated with Rosai-Dorfman disease vary depending upon the specific areas of the body that are affected. Systemic symptoms, such as fever, weight loss, malaise, joint pain, and night sweats, may be present. Cervical lymph nodes are most characteristically involved, but other areas, including extranodal regions, can be affected. These areas include the skin, central nervous system, kidney, and digestive tract.
What are the current treatments for Rosai-Dorfman Disease?
In many cases, the signs and symptoms of Rosai-Dorfman disease go away without any treatment (spontaneous remission) within months or a few years. When possible, the preferred course of management is continuous observation without treatment. Many individuals will not require therapy, but in some cases, various treatment options may become necessary. Treatment of the condition is then typically directed toward the specific symptoms that the affected individual has. Some individuals may need surgical removal of histiocytic lesions. In more serious cases, treatment options have included therapy with certain drugs including steroids (e.g., prednisone), alfa-interferon (a man-made copy of a protein that is normally made by the body in response to infection), chemotherapy and radiation therapy. These treatments have improved symptoms in some individuals, but in others they have not been effective. Other treatment is symptomatic and supportive.
