Histiocytoses, singular histiocytosis, are a rare set of conditions affecting tissue macrophages.
Historical classification of histiocytoses in a table
Features of histiocytoses:[1]
Histologic features | EM features | CD68 | S-100 | CD1a | Image | |
---|---|---|---|---|---|---|
Macrophage | epithelioid cells, giant cells | - | + | - | - | Macrophages - CD68 (WC) |
Erdheim-Chester disease | Touton giant cells | - | + | +/- | - | ECD (upmc.edu) |
Rosai-Dorfman | Emperipolesis | - | + | + | - | RDD (WC) |
Langerhans cell histiocytosis (LCH) | Reniform nuclei, eosinophilic cytoplasm |
Birbeck granules | + | + | + | LCH (WC) |
Notes:
- EM = electron microscopy.
The classification has evolved considerably, as the entities can overlap. An overview of a more recent classification is found in the article classification of histiocytoses and neoplasms of the macrophage-dendritic cell lineages.
