Dendritic cells are a form of histiocyte, or white blood cell. These cells play a role in the body’s immune system. They can be found in the skin, lungs, stomach, bone, eyes and intestines. Langerhans cells, which help regulate the immune system, are normally found throughout the body, especially in the skin, lymph nodes, spleen, lungs, liver, and bone marrow. In Langerhans cell histiocytosis, excess immature Langerhans cells usually form tumors called granulomas.

Langerhans cells, which help regulate the immune system, are normally found throughout the body, especially in the skin, lymph nodes, spleen, lungs, liver, and bone marrow. In Langerhans cell histiocytosis, excess immature Langerhans cells usually form tumors called granulomas. Langerhans cell histiocytosis (LCH) is caused by clonal expansion of myeloid precursors that differentiate into CD1a + /CD207 + cells in lesions that leads to a spectrum of organ involvement and dysfunction.
