What is Langerhans cell histiocytosis? Langerhans cell histiocytosis (also called histiocytosis X) is a rare disorder that primarily affects children. 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

Langerhans cell histiocytosis is a type of cancer that can damage tissue or cause lesions to form in one or more places in the body. Langerhans cell histiocytosis (LCH) is a rare cancer that begins in LCH cells. LCH cells are a type of dendritic cell which fights infection. Sometimes there are mutations (changes) in LCH cells as they form. Langerhans cell histiocytosis (LCH) is a rare cancer involving clonal proliferation of Langerhans cells, abnormal cells deriving from bone marrow and capable of migrating from skin to lymph nodes.Symptoms range from isolated bone lesions to multisystem disease. LCH is part of a group of syndromes called histiocytoses, which are characterized by an abnormal proliferation of histiocytes.

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. Histiocytic sarcoma (G), like Langerhans cell sarcoma (H), demonstrates large pleomorphic atypical cells; however, the cells of histiocytic sarcoma are generally larger than those of Langerhans cell sarcoma and show less nuclear complexity (hematoxylin-eosin, original magnification X400). Our assumptions on the identity and functions of Langerhans cells (LCs) of the epidermis have undergone considerable changes. Once thought to be prototypic representatives of the dendritic cell (DC) lineage, they are now considered to be a specialized subset of tissue-resident macrophages. Despite this, LCs display a remarkable mixture of properties. Like many tissue macrophages, they self Langerhans cells, along with other classes of dendritic cells, are universally found in all skin,.

Symptoms range from isolated bone lesions to multisystem disease. LCH is part of a group of syndromes called histiocytoses, which are characterized by an abnormal proliferation of histiocytes. These diseases are related to other forms of Celltypen som orsakar sjukdomen heter Langerhans celler, uppkallad efter den man som först påvisade dessa celler.

The Langerhans cell is a class of white blood cell. The symptoms and seriousness of Langerhans cell diseases are determined by where the proliferation of the Langerhans cell occurs. If the cells multiply and remain mostly in the skin, the result often is localized to the skin.

Förekomst Det årliga insjuknandet (incidensen) har uppskattats till 9 per miljon barn under 15 års ålder. 5 rows 2017-09-11 Langerhans cells (LC) are members of the dendritic cells family, residing in the basal and suprabasal layers of the epidermis and in the epithelia of the respiratory, digestive and urogenital tracts. They specialize in antigen presentation and belong to the skin immune system (SIS).

Box 117, 221 00 Lund, Sweden Langerhans´ cellhistiocytos (LCH) benämndes tidigare histiocytosis X, »a reactive, non-neoplastic proliferation of the Langerhans cells« [19].

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 cells function similarly in human and mouse and can be identified by the presence of Langerin/CD207-containing Birbeck granules. Both human and mouse Langerhans cells express MHC class II, E-Cadherin, EpCAM/TROP1, Integrin alpha X/CD11c, and Langerin/CD207.

Theodor Langhans (1839–1915) was the first to describe the multinucleate cells now known as Langhans cells Langerhans cells (LCs), as dendritic cells (DC) that play an important role in the immune system, are mainly distributed in the epidermis. This review focuses on the role of these epidermal LCs in regulating skin threats (such as microorganisms, ultraviolet radiation and allergens), especially psoriasis.

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.
