Immunophenotypic characterization of the cell infiltrate in five cases of sinus histiocytosis with massive lymphadenopathy (Rosai-Dorfman disease)

Hum Pathol. 1992 Jun;23(6):647-54. doi: 10.1016/0046-8177(92)90320-3.


Little is known about the nature of the large intrasinusoidal cells exhibiting cytophagocytosis, which are the histologic hallmark of sinus histiocytosis with massive lymphadenopathy (SHML) (Rosai-Dorfman disease). Using a broad panel of monoclonal and polyclonal antibodies, we analyzed the immunophenotype of the cell infiltrates in seven lymph node biopsy specimens from five cases of SHML. The SHML cells constantly expressed the S-100 protein, concanavalin agglutinin and peanut agglutinin lectins, and monocyte-macrophage-associated antigens CD 11c, CD 14, CD 33, CD 68, and LN 5. Labeling with other antimacrophage antibodies was extremely variable, with some (MAC 387, lysozyme) restricted to clusters of SHML cells and others (CD11b, CD 36, alpha-1-antichymotrypsin) staining only scattered cells. The CD 1a antigen was found on some cells in only one case, whereas HLA-DR and the HLA-DR-associated invariant chains were absent. The heterogeneity of SHML cell marker expression might be related to the local content of factors (eg, cytokines) capable of modulating the phenotype of monocytes and derived cells. All cases presented with huge amounts of medium-sized mononuclear cells accumulated in the sinuses and intersinusoidal tissue. These cells expressed the S-100-/CD 11b+/CD 11c+/CD 14+/CD 16+/CD 33+/CD 36+/lysozyme+/MAC 387+/HLA-DR+ phenotype. These recently immigrated monocytes might represent the immediate precursors of SHML cells.
