Histiocyte

Macrophage

A histiocyte is a type of immune cell. It destroys foreign substances to protect the body from infection.

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:

  • Brain
  • Breast tissue
  • Liver
  • Lung
  • Lymph nodes
  • Placenta
  • Spleen
  • Tonsils

An abnormal number of histiocytes leads to a disease called Langerhans cell histiocytosis (previously called histiocytosis X).
