Langerhans Cell Histiocytosis (LCH) is a very rare form of disorder that involves clonal proliferation of the Langerhans cells, the abnormal cells that are derived from the bone marrow which are capable of.. Granulomas also frequently occur in the skin, appearing as blisters, reddish bumps, or rashes which can be mild to severe. The pituitary gland may also be affected; this gland is located at the base of the brain and produces hormones that control many important body functions. Without hormone supplementation, affected individuals may experience delayed or absent puberty or an inability to have children (infertility). In addition, pituitary gland damage may result in the production of excessive amounts of urine (diabetes insipidus) and dysfunction of another gland called the thyroid. Thyroid dysfunction can affect the rate of chemical reactions in the body (metabolism), body temperature, skin and hair texture, and behavior.

Blood 2014;124:3007-3015.Unifocal LCH is also known as Eosinophilic Granuloma. It is a slow-progressing disease that is characterized by expanding proliferation of the Langerhans cells in the different bone structures. It is a polystotic or monostotic disease having no extraskeletal involvement. This is the main difference between eosinophilic granuloma and other types of LCH variants.

Letterer-Siwe disease (disseminated) has a high mortality rate. The prognosis in these patients depends on the patient's age, the extent of disease, and the degree of organ dysfunction. The mortality rate is 50% or higher.Langerhans cell histiocytosis is usually not inherited and typically occurs in people with no history of the disorder in their family.Billings TL, Barr R, Dyson S.

LCH has been commonly thought of as a cancerous condition, even if it is not so. Although the exact specific reason for the development of the disease is still under debate, recently the researchers are of the opinion that it is caused by an autoimmune disorder in which the immune cells attack the body by mistake instead of fighting infections. Tumors are formed by the extra immune cells that can affect various areas of the patient’s body, including the skull, bones and other areas. Genetic factors are believed to be responsible for some forms of LCH.TEXTBOOKS McClain KL, Allen CE. Inflammatory and Malignant Histiocytoses. In Williams Hematology, 9th Edition.

  1. 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. In Langerhans cell histiocytosis, excess immature Langerhans cells usually form tumors called granulomas. Many researchers now consider Langerhans cell histiocytosis to be a form of cancer, but this classification remains controversial.
  2. The remaining tissue consists of endocrine cells called islets of Langerhans. These clusters of cells look like grapes and produce hormones that regulate blood sugar and regulate pancreatic secretions

[24] Response to chemotherapy in the first 6 weeks (induction therapy) is among the most important prognostic indicators for multifocal LCH. A good response to chemotherapy during this period is associated with significantly improved survival. [4, 25] Conversely, hematologic involvement or involvement of organs such as the lungs, spleen, and liver is associated with worse long-term outcomes. [4]

The extensive variability in gene expression between these 2 cellular populations has prompted speculation that LCH cells may develop from a population of cells distinct from epidermal Langerhans cells. Specifically, it is hypothesized that "misguided" blood-derived myeloid dendritic cells are recruited to specific anatomic sites and their subsequent stimulation of T-cell trafficking and local immunomodulation is responsible for the characteristic lesions of LCH. [10] Notably, this hypothesis is consistent with either an oncogenic or reactive etiology for LCH, because what stimulates these misguided cells remains unclear.

LCH causes non-specific inflammatory response that includes lethargy, fever and weight loss. More specific symptoms are caused by organ involvement.Although the epidermal Langerhans cell has been presumed to be the cell of origin in LCH, recent studies have called this belief into question. Specifically, a variety of other cellular populations have been identified that possess phenotypic characteristics similar to Langerhans cells, including expression of CD207 and Birbeck granules. Therefore, in addition to epidermal Langerhans cells, other potential cellular origins for LCH include dermal langerin+ dendritic cells, lymphoid tissue-resident langerin+ dendritic cells, and monocytes that can be induced by local environmental stimuli to acquire a Langerhans cell phenotype.

Langerhans cell histiocytosis. Published by TBP. Presentation. Age: 25. Gender: Female. Spine- Langerhans cell histiocytosis Erdheim-Chester disease (ECD) is caused by mutations of the MAPkinase pathway, most often the BRAF V600E mutation. ECD affects the lungs, heart, and kidneys by forming “rinds” around these organs and is characterized by excessive production and accumulation of histiocytes within multiple tissues and organs. (Diamond) Histiocytes are large phagocytic cells (macrophages) that normally play a role in responding to infection and injury. (A phagocytic cell is any “scavenger cell” that engulfs and destroys invading microorganisms or cellular debris.) In those with ECD, sites of involvement may include the long bones, skin, tissues behind the eyeballs, lungs, brain, pituitary gland, and/or additional tissues and organs. Associated symptoms and findings and disease course depend on the specific location and extent of such involvement. The specific underlying cause of ECD is unknown. ECD patients have increased density (sclerosis) in the tibiae (lower leg bones) as well as abnormal tissue wrapping around the kidneys, heart, aorta, and bronchi.

Others may have more severe disease involving many organs within the body. This can be fatal. The predictors of a poor outcome are:The diagnostic work-up may include X-rays of the skull, a complete skeletal bone survey and PET scan, chest x-ray, complete blood count and differential, erythrocyte sedimentation rate, liver function tests including AST, ALT, bilirubin, and albumin; electrolytes and urinalysis. (Phillips) CT of the skull if mastoids involved. Pulmonary disease: high resolution CT. Brain: MRI. Diabetes insipidus: water deprivation test or serum and urine osmolality. Langerhans cell histiocytosis (LCH) is a rare disease characterized by an abnormal proliferation of histiocytes, an archaic term for activated dendritic cells and macrophanges The appearance of the rash or X-rays and scans of internal organs may give the doctor a clue to the diagnosis. A skin biopsy of the affected area is usually needed to confirm the diagnosis. The biopsy findings do not give any indication of the likely course of the disease.Grois N, Potschger U, Prosch H, et al. Risk factors for diabetes insipidus in langerhans cell histiocytosis.

[Full Text]. Langerhans-Cell Histiocytosis A spectrum of diseases formerly known as histiocytosis X and now called Langerhans-cell histiocytosis is characterized by ERK pathway activation.. Langerhans cell histiocytosis, abbreviated LCH, is a rare disorder of tissue macrophages. It broadly fits into the category of histiocytoses. It used to known as eosinophilic granuloma. It has been referred to by several eponyms - Hand-Schüller-Christian disease.. Some studies have also indicated that expression of vascular endothelial growth factor (VEGF); Bcl-2 family proteins; and FADD, FLICE, and FLIP proteins in the Fas signaling pathway may be involved in the pathogenesis of LCH. [14, 15, 16] The E-cadherin-beta-catenin-Wnt signaling pathway has also been implicated in LCH, and down-regulation of E-cadherin may be associated with disease dissemination. [3, 17]
