The disease spectrum results from clonal accumulation and proliferation of cells resembling the epidermal dendritic cells called Langerhans cells, sometimes called dendritic cell histiocytosis. These cells in combination with lymphocytes , eosinophils , and normal histiocytes form typical LCH lesions that can be found in almost any organ . [ 5 ]
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 ...
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 ...
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 a suspected antiphospholipid syndrome, lupus anticoagulant is generally tested in conjunction with anti-apolipoprotein antibodies and anti-cardiolipin antibodies, and diagnostic criteria require one clinical event (i.e. thrombosis or pregnancy complication) and two positive blood test results spaced at least three months apart that detect at ...

Undifferentiated connective tissue disease (UCTD) (also known as latent lupus or incomplete lupus [1]) is a disease in which the connective tissues are targeted by the immune system. It is a serological and clinical manifestation of an autoimmune disease .
