Rosai-Dorfman disease synonyms

TL;DR: Rosai-Dorfman disease, also known as sinus histiocytosis with massive lymphadenopathy (SHML), is a rare disorder characterized by the accumulation of specific immune cells. While historical literature may refer to it by several names based on its discovery, Rosai-Dorfman disease is the currently preferred clinical term used by medical professionals worldwide.

What are the historical and alternative names for Rosai-Dorfman disease?

In medical literature, Rosai-Dorfman disease has been referred to by several titles, often reflecting the clinical presentation of the condition. The most prominent synonym is "sinus histiocytosis with massive lymphadenopathy," which describes the hallmark enlargement of lymph nodes caused by the infiltration of histiocytes. Occasionally, you may encounter the term "Destombes-Rosai-Dorfman disease" in European literature, acknowledging the contributions of Pierre Destombes, who described similar histological findings prior to the definitive work of Juan Rosai and Ronald Dorfman in 1969. Because the condition can present in tissues outside of the lymph nodes, it is sometimes referred to as "extranodal Rosai-Dorfman disease" when it affects organs like the skin, eyes, or central nervous system.

Why does Rosai-Dorfman disease have so many names?

The variety of names associated with Rosai-Dorfman disease stems from the evolution of pathological understanding. Initially, researchers described the condition based on the visible symptoms, such as the "massive lymphadenopathy" observed in the neck. As diagnostic technology improved, medical experts realized that the disease could manifest in various parts of the body, leading to the distinction between nodal and extranodal forms. The medical community eventually standardized the name to honor the pathologists who first characterized the disease's unique "emperipolesis"—a process where histiocytes engulf other white blood cells without destroying them—which remains the diagnostic hallmark of Rosai-Dorfman disease.

How is the disease classified in official medical systems?

Standardized nomenclature is essential for clinical coding and research. In major international databases, the condition is categorized as follows:

• Orphanet: Listed under ORPHA:802 (Rosai-Dorfman disease).


• OMIM: Documented as #619574, reflecting its classification as a histiocytic disorder.


• ICD-10/11: Often coded under broader categories for "Langerhans cell histiocytosis and other histiocytoses" or specific codes related to lymphadenopathy.

Which name should patients use when communicating with their doctors?

While your medical records might contain older terms like "sinus histiocytosis with massive lymphadenopathy," Rosai-Dorfman disease is the preferred clinical term in modern oncology, hematology, and pathology. Using this specific name ensures that your healthcare team is accessing the most current research and diagnostic guidelines.
