Langerhans cell histiocytosis (LCH) in adults is a lot like LCH in children and can form in the same organs and systems as it does in children. These include the endocrine and central nervous systems, liver, spleen, bone marrow, and gastrointestinal tract. In adults, LCH is most commonly found in the lung as single-system disease. LCH in the lung occurs more often in young adults who smoke. Adult LCH is also commonly found in bone or skin.
As in children, the signs and symptoms of LCH depend on where it is found in the body. See the General Information section for the signs and symptoms of LCH.
Incidence and Mortality
Estimated new cases and deaths from testicular cancer in the United States in 2014:
New cases: 8,820.
Testicular cancer is a highly treatable, usually curable, cancer that most often develops in young and middle-aged men. Most testicular cancers are germ cell tumors. For treatment planning, germ cell tumors are broadly divided into seminomas and nonseminomas because they have different prognostic and treatment algorithms. For patients with...
Tests that examine the organs and body systems where LCH may occur are used to detect (find) and diagnose LCH. See the General information section for tests and procedures used to diagnose LCH.
In adults, there is not a lot of information about what treatment works best. Sometimes, information comes only from reports of the diagnosis, treatment, and follow-up of one adult or a small group of adults who were given the same type of treatment.
Treatment Options for LCH of the Lung in Adults
Treatment for LCH of the lung in adults may include:
Quitting smoking for all patients who smoke. Lung damage will get worse over time in patients who do not quit smoking. In patients who quit smoking, lung damage may get better or it may get worse over time.
