    Abstract:
    We report a case of a 31-year-old HIV infected black female, who presented with asymptomatic generalized lymphadenopathy. Three particularly enlarged lymph nodes were biopsied (2 cervical and 1 axillary). The histological picture was consistent with a diagnosis of sinus histiocytosis with massive lymphadenopathy (SHML) or Rosai-Dorfman disease. Large histiocytes, positive for a variety of macrophage markers and for the S-100 protein, were observed in the distended sinuses. A few hyperplastic follicles, such as usually seen in HIV-infection-associated lymphadenopathy, were present at the periphery of one lymph node. No infections agent besides HIV could be detected by histological or microbiological analysis or by in situ hybridization. This is the first reported case of SHML associated with HIV infection. The possible relationship between the two diseases is discussed.
