title: Sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease) in a patient with elevated Epstein-Barr virus titers.
abstract: Sinus histiocytosis with massive lymphadenopathy (SHML) is a newly recognized disorder. The etiology of this disease is unknown. An exaggerated response to an offending agent such as the Epstein-Barr virus or Klebsiella bacteria has been postulated. Its course is usually benign. Cervical adenopathy is seen in 97% of the patients, while 30% of patients have nodal involvement in other sites, and 30% have extranodal involvement. There is a 7% mortality rate that occurs primarily in patients with immunologic defects. Corticosteroids ameliorate the constitutional symptoms, but cyclophosphamide appears to have the most beneficial effect. This article presents the case of a patient with SHML who demonstrated elevated Epstein-Barr virus titers.
