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, usually self-limited.[2]

Clinical findings:[3][2]

  • Fever.
  • Leukocytosis with neutrophilia.
  • Polyclonal gammaglobulinemia.

Gross

  • Skin: nodules.[2]

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.
  • Emperipolesis (from Greek: em = inside, peri = around, polemai = wander about[5]):
    • Histiocytes contain other whole cells: neutrophils, lymphocytes, plasma cells.
      • The "eaten" cell is within a vacuole;[6] thus, it should have a clear halo around it.
      • Thought to be related to peripolesis; the attachment of a cell to another.[7]
