Langerhans-cell granulomatos kan involvera ett enda organ eller kan vara en the abnormal proliferation of and tissue infiltration by LANGERHANS CELLS 

Having fun in the sun sounds like a great idea. But too much fun without protecting your skin from harmful UV rays from the sun can, unfortunately, lead to the development of basal cell carcinoma — the most common, but least dangerous of th

Other disorders similar to LCH include Histiocytoses Rosai-Dorfman, juvenile xanthogranuloma, and Erdheim-Chester disease but they do not share the exact phenotypic signature of LCH. Langerhans cells (LCs) reside in the epidermis as a dense network of immune system sentinels. These cells determine the appropriate adaptive immune response (inflammation or tolerance) by interpreting the microenvironmental context in which they encounter foreign substances. In a normal physiological, “non-dangerous” situation, LCs coordinate a continuous state of immune tolerance Langerhans cells makes up 3–5% of the cells in the stratum spinosum [4]. Langerhans cells and melanocytes are connected to adjacent cells by desmosomes the same way keratinocytes are connected to one another. Langerhans cells are derived from the monocyte lineage and function in the afferent limb of the immune response. Langerhans cell histiocytosis is a disorder in which excess immune system cells called Langerhans cells build up in the body.

Because of their dendrite -like appearance, he mistakenly identified the cells as part of the nervous system . Langerhans cells makes up 3–5% of the cells in the stratum spinosum [4]. Langerhans cells and melanocytes are connected to adjacent cells by desmosomes the same way keratinocytes are connected to one another. Langerhans cells are derived from the monocyte lineage and function in the afferent limb of the immune response. Langerhans cell histiocytosis (LCH) is a disorder that primarily affects children, but is also found in adults of all ages. People with LCH produce too many Langerhans cells or histiocytes, a form of white blood cell found in healthy people that is supposed to protect the body from infection.

These cells determine the appropriate adaptive immune response (inflammation or tolerance) by interpreting the microenvironmental context in which they encounter foreign substances.

In all mammalian species so far examined, Langerhans cells or their precursors are the only epidermal cells expressing Ia antigens or their equivalents. In man, xeno-antisera raised in rabbits against purified B-lymphocyte cell membrane antigens were utilized to stain the Langerhans cells by either fluorescent or immunoferritin methods.

Langerhans cell histiocytosis is a disorder in which excess immune system cells called Langerhans cells build up in the body. 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.

This disorder is characterized by an abnormal increase in certain immune cells called histiocyte cells. Histiocyte cells are a form of white blood cells that help the immune system destroy foreign materials and fight infection.
