Histiocytoses, singular histiocytosis, are a rare set of conditions affecting tissue macrophages.
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.
Langerhans cell histiocytosis
Main article: Langerhans cell histiocytosis
IHC
Langerin (CD207).[2]
Erdheim-Chester disease
- Abbreviated ECD.
General
- Rare.
- Clonal proliferation of histiocytes; 3 of 5 cases shown monoclonal by Chetritt el al.[3]
Gross
Features:
- Bone involvement - classic.
- Usually multiple systems are involved.
Note:
- Does not usually involve the lymph nodes - like Rosai-Dorfman disease.
Microscopic
Features:[4]
- Foamy histocytes.
- Large cells with gray, bubbly cytoplasm.
- +/-Touton giant cells - very distinctive histiocytes - classic.
- Nuclei form a ring around the cell periphery.

IHC
Features:[5]
- CD68 +ve.
- S100 -ve/+ve.
- CD1a -ve.
