Langerhans cell histiocytosis (LCH) 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 . [ 1 ]
Chronic multifocal Langerhans cell histiocytosis; Other names: Hand–Schüller–Christian disease: A child with Hand-Schüller-Christian Disease: Specialty: Dermatology: Symptoms: Triad of bulging eyes, breakdown of bone, diabetes insipidus [1] Other symptoms eg. bone pain, facial asymmetry, ear infections, teeth/gum problems, liver and lung ...
Letterer–Siwe disease, (LSD) or Abt-Letterer-Siwe disease, is one of the four recognized clinical syndromes of Langerhans cell histiocytosis (LCH) and is the most severe form, involving multiple organ systems such as the skin, bone marrow, spleen, liver, and lung. Oral cavity and gastrointestinal involvement may also be seen.
In the rare disease Langerhans cell histiocytosis (LCH), an excess of cells similar to these cells are produced. However LCH cells stain positive to CD14 which is a monocyte marker and shows a different, hematopoietic origin for the disorder. [12] LCH can cause damage to skin, bone and other organs.

First described in 1961 (where they were simply termed "characteristic granules"), [2] they are solely found in Langerhans cells. [1] Although part of normal Langerhans cell histology, they also provide a mechanism to differentiate Langerhans cell histiocytoses (which are a group of rare conditions collectively known as histiocytoses ) from ...
According to the Histiocytosis Association, 1 in 200,000 children in the United States are born with histiocytosis each year. [2] HAA also states that most of the people diagnosed with histiocytosis are children under the age of 10, although the disease can afflict adults. The disease usually occurs from birth to age 15.

Hashimoto–Pritzker disease, [1] ... Congenital self-healing reticulohistiocytosis is a condition that is a self-limited form of Langerhans cell histiocytosis. [2]: ...
Non-Langerhans cell histiocytosis, also known as rare histiocytoses, comprise all histiocyte, macrophage, and dendritic cell proliferative disorders that are not categorized as hemophagocytic lymphohistiocytosis (HLH) or Langerhans cell histiocytosis (LCH). [1] The spectrum of non-langerhans cell histiocytoses include: Benign cephalic histiocytosis
