Information
Histiocytes do not travel through the blood. Instead, they remain in one part of the body.
Histiocytes are found in many organs and tissues, including the following:
- Brain
- Breast tissue
- Liver
- Lymph nodes
- Placenta
- Spleen
- Tonsils
An abnormal number of histiocytes leads to a disease called Langerhan’s cell histiocyosis (previously called histiocytosis X).
