In general, Langerhans cells in situ and freshly isolated Langerhans cells represent functionally 'immature' dendritic cells. They express lower levels of cell surface MHC class II molecules and stimulate resting T cells less well in mixed lymphocyte reactions when compared to 'mature' dendritic cells, e.g. peripheral blood dendritic cells Langerhans cell histiocytosis is an abnormal 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. These diseases are related to other forms of abnormal proliferation of white blood cells, such as leukemias and lymphomas.

Langerhans cell definition is - a cell found in the epidermis that functions as an antigen-presenting cell which binds antigen entering through the skin The World Health Organization classification of hematopoietic and lymphoid tumors classifies Langerhan cell histiocytosis (LCH) as a dendritic cells disorder. This grouping includes Langerhans cell histiocytosis, secondary dendritic cell processes, juvenile xanthogranuloma, solitary histiocytomas with a dendritic phenotype and Erdheim-Chester. Langerhans cells, along with other classes of dendritic cells, are universally found in all skin,. There is minimal variation between parts of the body in their content of Langerhans cells. They are found in all genital tissue including the glans, foreskin, shaft, scrotum, clitoris, clitoral hood, labia, and vagina Causes. We don't know all the reasons why some people get LCH. About half of the people with the disorder have a faulty gene that makes the Langerhans immune cells grow out of control Langerhans cell histiocytosis is due to uncontrolled monoclonal proliferation of Langerhans cells (distinctive cells of monocyte-macrophage lineage) and should be considered a malignancy although its biological behavior is very variable 1,3 .

Abstract. Langerhans cells (LCs) are intraepidermal dendritic cells that extend their dendrites between keratinocytes to form a dense network that covers the entire body. The mammalian epidermis has two diffusion barriers, the stratum corneum and tight junctions (TJs). In their resting state, LCs sit underneath these two barriers Langerhans' cell histiocytosis. Langerhans' cell histiocytosis (LCH) is a very rare condition with a high survival rate. Histiocyte cells normally help protect the skin, but sometimes the body has too many of them and they move around the body, causing damage. LCH can affect bones or organs and the symptoms present in a number of different ways Langerhans and Dermal Dendritic Cells. As part of the first line of defense against exogenous pathogens, the skin houses a number of highly specialized dendritic cell (DC) subsets. Following antigen recognition, skin-localized DCs migrate to skin-draining lymph nodes where they induce an immune response or promote tolerance Indeed, in the past we have shown in skin equivalents with integrated Langerhans Cells (SE-LC) that upon allergen exposure MUTZ-3 LC mature and migrate in a CXCL12 dependent manner from the epidermis to the dermis, whereas upon irritant exposure MUTZ-3 LC migrate in a CCL5 dependent manner and undergo an IL-10 dependent phenotypic switch into a macrophage-like cell in the dermis, closely. Langerhans cell histiocytosis (LCH), characterized by intense and abnormal proliferation of bone marrow-derived histiocytes (Langerhans cells), is a rare disease of unknown pathogenesis, leading to its high rate of misdiagnosis and missed diagnosis . Here we introduce a case of LCH by reviewing related literatures and focus on the clinical.

Langerhans cell histiocytosis is a rare disease that tends to affect children and adolescents. The median age at diagnosis depends on the specific subtype of the disease. The incidence of Langerhans cell histiocytosis is approximately 0.5 per 100,000 individuals in the United States. Males are more commonly affected with Langerhans cell. Langerhans cells (LCs) are resident macrophages in skin epidermis, where they have immune-stimulatory capacities. Under both steady and inflammatory conditions, upon activation, LCs migrate from the epidermis to the skin-draining lymph nodes to present antigens to T cells, resulting in the activation of acquired immunity (Hemmi et al., 2001; Merad et al., 2008; Romani et al., 2010; Stoitzner.
