Immunohistochemistry reveals expression of the following antigens: Imaging features are often not pathognomonic and tissue diagnosis is usually required for definitive diagnosis. Although Langerhans cell histiocytosis (LCH) is a familiar entity to most radiologists and to pediatric radiologists in particular, it is but one of a group of disorders caused by the overproduction of histiocytes, a subtype of white blood cells. Arising from the aberrant accumulation of Langerhans and other immune cells, PLCH tends to cause a relatively isolated pulmonary involvement as compared to other forms of Langerhans cell (LC) and histiocytic disorders. Langerhans cell histiocytosis is due to uncontrolled monoclonal proliferation of Langerhans cells (distinctive cells of monocyte-macrophage lineage) and should be considered a malignancy although its biological behaviour is very variable 1,3. Langerhans cell histiocytosis (LCH) is a group of idiopathic disorders characterized by the presence of cells with characteristics similar to bone marrow–derived Langerhans cells juxtaposed against a backdrop of hematopoietic cells, including T-cells, macrophages, and eosinophils. As well as systemic disease, individual organ systems may be involved, which will be discussed separately: The remainder of this article concerns a general overview of LCH. In people with LCH, these cells multiply excessively and build up in certain … Jun 14, 2015 - This case was donated to Radiopaedia.org by Radswiki.net.
