Rosai-Dorfman disease, abbreviated RDD, is a rare lymph node pathology.
It is also known as sinus histiocytosis with massive lymphadenopathy,[1] abbreviated SHML.
General
- Super rare.
- Prognosis - good.[2]
- Fever.
- Leukocytosis with neutrophilia.
- Polyclonal gammaglobulinemia.
Microscopic
Features:
- Sinus histiocytosis:
- Histiocytes - abundant.
- Singular large round nuclei[4] ~2x the size of resting lymphocyte.
- Prominent nucleolus - visible with 10x objective.
- Abundant cytoplasm.
- Singular large round nuclei[4] ~2x the size of resting lymphocyte.
- Histiocytes - abundant.
- Emperipolesis (from Greek: em = inside, peri = around, polemai = wander about[5]):
DDx:
- Other specific histiocytoses:
- Infection, e.g. rhinoscleroma (nasopharynx), xanthogranulomatous pyelonephritis.
- Sinus histiocytosis.
- Xanthomatous change.

- RDD - case 1 - several images (upmc.edu).
- RDD - case 2 - several images of breast (upmc.edu).
- RDD - case 3 - several images (upmc.edu).
- RDD - case 4 - several images (upmc.edu).
IHC
- CD68 +ve.
- S-100 +ve.
- Useful for seeing emperipolesis.
- CD1a -ve.
- CD1a +ve in Langerhans cell histiocytosis.
