[Lymphadenopathy caused by hemophagocytic sinus histiocytosis (Destombes-Rosai-Dorfman syndrome). Immunologic and histopathologic study of a new case].
The case reported is one of lymphadenopathy due to haemophagocytic sinusal histiocytosis which had progressed for more than 10 years before resulting in death at the age of 58 years. In this advanced form, all superficial and deep nodes were involved. In addition to histiocytic hyperplasia, with haemophagocytosis and lipid overload, there was plasmocytic hyperplasia, i.e. B-lymphocytes, with polyclonal hypergamma-globulinaemia and an increase in the levels of many antibodies, in particular against rubella and the Epstein-Barr virus. The aetiopathological significance is discussed, in particular the role of an infection due to the EB virus.
