Multifocal multisystem LCH, also called Letterer-Siwe diseaseis a rapidly progressing disease in which Langerhans Cell cells proliferate in many tissues. American Journal of Clinical Pathology. With the necropsy was found a circular, multilobuled, hard, hemorrhagic mass with a diameter of 6 cm located in the cranial mediastine; in the abdominal cavity, metastases of the neoplasm to the liver and spleen.
CD1 positivity are more specific. When found in the lungs, it should be distinguished from Pulmonary Langerhans cell hystiocytosis—a special category of disease most commonly seen in adult smokers.

Langerhans cell histiocytosis — Wikipedia Seen mostly in children, multifocal unisystem LCH is characterized by fever, bone lesions and diffuse eruptions, usually on the scalp and in the ear canals. Unifocal LCH, also called eosinophilic granuloma an older term which is now known to be a misnomeris a slowly progressing malgina characterized by an expanding proliferation of Langerhans cells in various bones.
MRI and CT may show infiltration in sella turcica. Arguments supporting the reactive nature of LCH include the occurrence of spontaneous remissions, the extensive secretion of multiple cytokines by dendritic cells and bystander-cells a phenomenon known as cytokine storm in the lesional tissue, favorable prognosis and relatively good histocitosis rate in patients without organ dysfunction or risk organ involvement.
Two independent studies have confirmed this finding. Chemotherapeutic agents such as alkylating agentsantimetabolitesvinca alkaloids either singly or in combination can lead to complete remission in diffuse disease. Robin; Hoang, Mzligna P. LCH is usually a sporadic and non- hereditary condition but familial clustering has been noted in limited number of cases.
Excellent for single-focus disease. Hiistiocitosis malignant systemic histiocytoses is a disease slightly common of dogs and cats, that has been characterize by the neoplasic proliferation of macrofhages in hisitocitosis organs and systems.
Among children under the age of 10, yearly incidence is thought to be 1 in ,;  and in adults even rarer, in about 1 inLCH provokes a non-specific inflammatory responsewhich includes fever, lethargyand weight loss.
