Definition / general
- Massive painless bilateral lymph node enlargement in neck, of unknown etiology
- Rare; 25% involve extranodal sites (skin, upper respiratory tract, bone) but massive lymphadenopathy is usually also present
Terminology
- Also called Rosai-Dorfman disease
Clinical features
- Associated with fever, leukocytosis, anemia, elevated sedimentation rate, polyclonal hypergammaglobulinemia
- Usually age 20 years or less but can affect any age
- Initial cases from South Africa; now from U.S., Western Europe, Africa and Caribbean
- May spontaneously resolve; extranodal cases may persist for decades
- May cause death due to amyloidosis, involvement of a vital organ or immunologic abnormalities
- May coexist with lymphoma in same node (Mod Pathol 2000;13:414)

- Associated with Hodgkin disease (Hum Pathol 1995;26:1378)
Treatment
- None in most cases
Microscopic (histologic) description
-
Lymph node:
- Distinctive features are emperipolesis, plasma cells, distention of nodal sinuses
- Capsular and pericapsular inflammation and fibrosis
- Dilated sinuses filled with large histiocytes containing intact lymphocytes (emperipolesis, lymphocytophagocytosis) and with extremely large, round, vesicular nuclei with a delicate nuclear membrane and prominent nucleoli
- Histiocytes may exhibit atypia and be multinucleated
- Polyclonal plasma cells and lymphocytes
- Plasma cells frequently surround prominent high endothelial venules
- Remaining node contains plasma cells with Russell bodies
- No / rare internodal fibrosis
Microscopic (histologic) images
Cytology description
- Histiocytes with large nuclei and emperipolesis
- Lymphocytes are within cytoplasmic vacuoles
- Histiocytes may have atypia; also reactive lymphocytes (Diagn Cytopathol 2001;24:42)
Molecular / cytogenetics description
- Not clonal
Differential diagnosis
- Langerhans cell histiocytosis: prominent eosinophils, smaller nuclei with central grooves, indistinct nucleoli, no lymphophagocytosis although may have erythrophagocytosis, CD1a+
- Leprosy
- Metastatic melanoma
- Prosthesis related changes
- Sinus histiocytosis: no emperipolesis, S100-
- Toxoplasmosis: see Leuk Lymphoma 2004;45:1037
