How common is Langerhans cell histiocytosis in adults?
Adult histiocyte disorders are rare diseases. The most common of these is Langerhans cell histiocytosis (LCH), which affects only a few hundred patients every year in the United States. LCH results from the body's overproduction of immature histiocytes, which are a type of white blood immune cell.

What is lung cell histiocytosis?
Pulmonary Langerhans cell histiocytosis (PLCH) is proliferation of monoclonal Langerhans cells in lung interstitium and airspaces. Etiology is unknown, but cigarette smoking plays a primary role. Symptoms are dyspnea, cough, fatigue, and pleuritic chest pain. Diagnosis is based on history and imaging tests and sometimes on bronchoalveolar lavage and biopsy findings. Treatment is smoking cessation. Corticosteroids are given in many cases, but efficacy is unknown. Lung transplantation is usually curative when combined with smoking cessation. Five-year survival is about 74%. Patients are at increased risk of cancer.
Is a pulmonary function test normal?
Pulmonary function test findings are normal, restrictive, obstructive, or mixed depending on when the test is done during the course of the disease. Most commonly, the diffusing capacity for carbon monoxide (DLCO) is reduced and exercise is impaired.
How does PLCH affect patients?
The most frequently reported symptoms include shortness of breath on exertion, and cough. Some patients experience fatigue, weight loss and sometimes even a low grade fever.
What is the best test for PLCH?
Diagnosis and Treatment. The most important diagnostic test in patients with suspected PLCH is a CT scan of the chest (CAT scan). In many patients, the CT scan may show changes that are highly suggestive of PLCH (the presence of cysts and/or nodules).
What causes PLCH in adults?
While the precise cause of PLCH remains unknown, almost all adults with PLCH (about 95%) have either smoked cigarettes or have been exposed to substantial second-hand smoke. It is believed that cigarette smoke causes activation and accumulation of specific immune cells in the lungs (Langerhans cells) which leads to a cascade of inflammation and injury to the bronchial tubes and lung tissue over time. In addition to cigarette smoke, there may also be a subset of patients where PLCH is caused by genetic mutations. Recent research has shown that mutations of the BRAF gene have been linked to the development of PLCH. Other mutations have been identified. The occurrence of BRAF or other mutations suggests that at least a proportion of PLCH may be a low-grade cancer.
What is the name of the condition where the lungs collapse?
Approximately 15% of patients with PLCH may experience a pneumothorax (lung collapse due to leakage of air around the lungs). The common symptoms of a pneumothorax are sudden onset chest pain and shortness of breath, typically more on one side.

What is Langerhans cell histiocytosis?
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. In people with LCH, these cells multiply excessively and build up in certain areas of the body, causing tumors called granulomas to form. [1] The symptoms of LCH vary from person to person, depending on the areas of the body affected. LCH may be found in many areas of the body, including but not limited to the skin and nails, mouth, bones, lymph nodes, pituitary gland, and thyroid gland. When it is found in multiple areas of the body, it is known as multisystem disease. [1] [2] The cause of this disease is unknown, although most data suggest that it is characterized by a growth of immature Langerhans cells that appear to have mutations of the BRAF gene in about half the cases. LCH is not caused by a known infection, is not contagious, nor is it believed to be inherited. There remain differing opinions among experts as to whether it is definitively a cancer or not. [1] [3] Treatment for LCH varies and may include surgery, chemotherapy, radiation therapy, and use of certain medications. [3] [2]
What are the symptoms of lymph nodes?

Is LCH a cancer?
LCH is not caused by a known infection, is not contagious, nor is it believed to be inherited. There remain differing opinions among experts as to whether it is definitively a cancer or not. [1] [3] Treatment for LCH varies and may include surgery, chemotherapy, radiation therapy, and use of certain medications. [3] [2]
What is PLCH in lung?
Pulmonary Langerhans cell histiocytosis (PLCH) is a rare sporadic cystic lung disease of unknown aetiology that is characterised by the infiltration and destruction of the wall of distal bronchioles by CD1a+Langerhans-like cells. In adults, PLCH is frequently isolated and affects young smokers of both sexes.
What is LCH in biology?
Introduction. Langerhans cell histiocytosis (LCH) is a rare disorder of unknown aetiology that is characterised by the infiltration of involved tissues by dendritic cells sharing phenotypic similarities with Langerhans cells, which are often organised into granulomas [1].
What is HRCT in PLCH?
HRCT is mandatory for every suspected case of PLCH [ 8, 9 ]. It can visualise parenchymal lesions, such as nodules or cysts that are not readily visible on standard chest radiography. The typical HRCT pattern combines small, poorly limited nodules, cavitated nodules and thick- and thin-walled cysts predominantly in the upper and middle lung fields, with a relative sparing of the bases. The lesions are focal and are separated by apparently normal parenchyma, and they affect both the peripheral and the central parts of the lung fields.
What are the symptoms of a symtom?
1) Respiratory symptoms (cough and dyspnoea on exertion), which occur in approximately two-thirds of all such cases. Constitutional manifestations (asthenia, fever, night sweats and weight loss) may be associated with 10–20% of these patients. 2) Spontaneous pneumothorax, which is observed in 15–20% of cases.
Is cladribine a purine?
Cladribine (2-chlorodeoxyadenosine), which is a purine nucleoside analogue and is directly toxic for lymphocyte and monocyte cells, has been used as a second-line treatment in multisystem LCH [91, 92] and has been reported to induce remission or improve lung disease in several PLCH cases [18, 93–96].
Is bronchial tree normal?
The macroscopic appearance of the bronchial tree is normal or shows only nonspecific inflammation related to smoking. Bronchial mucosa biopsy specimens do not confirm the diagnosis of PLCH, but are helpful for ruling out an alternative diagnosis in atypical cases.
