Classification of histiocytoses and neoplasms of the macrophage-dendritic cell lineages is an evolving classification published by the Histiocyte Society.
The version published in 2016 consists of five groups:[1]
Group | Diseases | Details |
---|---|---|
L group | Langerhans cell histiocytosis (LCH), indeterminate cell histiocytosis, Erdheim-Chester disease (ECD), mixed LCH/ECD | |
C group | cutaneous non-LCH, cutaneous non-LCH with major systemic component | cutaneous non-LCH subdivided into: XG family JXG, non-XG family |
R group | familial Rosai-Dorfman disease (RDD), sporadic RDD | sporadic RCC includes: classical RDD, extra-nodal RDD, RDD with neoplasia or autoimmune disease, unclassified RDD |
M group | primary malignant histiocytoses, secondary malignant histiocytoses | secondary malignant histiocytosis follow another hematologic malignancy; subclassified as: histiocytic, interdigitating, Langerhans, indeterminate cell |
H group | primary hemophagocytic lymphohistiocytosis (HLH), secondary hemophagocytic lymphohistiocytosis, HLH or unknown/uncertain origin | secondary HLH is non-Mendelian |
Lame way to remember the groupings: Malignant Histiocytoses Can Result in Lifelessness.
