| histiocytosis, langerhans-cell | Group of disorders of histiocyte proliferation which includes letterer-siwe disease, hand-schueller-christian syndrome, and eosinophilic granuloma. Langerhans cells are components of the lesions. (12 Dec 1998) |
|---|---|
| histiocytosis, non-langerhans-cell | Group of disorders which feature accumulations of active histiocytes and lymphocytes, but where the histiocytes are not langerhans cells. The group includes haemophagocytic lymphohistiocytosis, infection-associated haemophagocytic syndrome, sinus histiocytosis, xanthogranuloma, reticulohistiocytoma, juvenile xanthoma, xanthoma disseminatum, as well as the lipid storage diseases (sea-blue histiocyte syndrome and niemann-pick disease). (12 Dec 1998) |
| langerhans cell | Paul langerhans, german pathologist, 1847-1888 1. Star-shaped cells in the deeper portions of the germinative layer of the epidermis. 2. Irregulare wandering cells in the intercellular spaces of rhe cornea. Synonym: Langerhans stellate corpuscles. (16 Dec 1997) |
| langerhans cell histiocytoses | An immunologic disorder of unknown cause where there is proliferation of histiocytes (a type of cell in the immune system) in the bloodstream. The disorder is characterised by inflammation of the bronchioles and small pulmonary vessels that leads to fibrosis and destruction of alveolar cell walls. Cigarette smoking is considered a risk factor. Individuals with this disorder are also at increased risk for spontaneous pneumothorax. Symptoms include cough, chest pains, shortness of breath, fever, weight loss and malaise. Bronchoscopy with biopsy confirms the diagnosis. Childhood forms exist and cause more systemic symptoms and findings such as failure to thrive, weight loss, fevers, irritability, rash and bone pains. Treatment is with corticosteroids. (27 Sep 1997) |
| Islets of Langerhans | <anatomy> Groups of cells found within the pancreas: A cells and B-cells secrete insulin and glucagon. See: D cells. (18 Nov 1997) |
| islets of langerhans transplantation | The transference of pancreatic islets within an individual, between individuals of the same species, or between individuals of different species. (12 Dec 1998) |
| Langerhans | <anatomy> Groups of cells found within the pancreas: A cells and B-cells secrete insulin and glucagon. See: D cells. (18 Nov 1997) |
| langerhans cells | Recirculating, dendritic, antigen-presenting cells containing characteristic racket-shaped granules (birbeck granules). They are found principally in the stratum spinosum of the epidermis and are rich in class II major histocompatibility complex molecules. (12 Dec 1998) |
| Langerhans' cells | Dendritic clear cell's in the epidermis, containing distinctive granules that appear rod-or racket-shaped in section, but lacking tonofilaments, melanosomes, and desmosomes; they carry surface receptors for immunoglobulin (Fc) and complement (C3), and are believed to be antigen fixing and processing cell's of monocytic origin; active participants in cutaneous delayed hypersensitivity. (05 Mar 2000) |
| Langerhans' granule | A small tennis racket-shaped membrane-bound granule with characteristic cross-striated internal ultrastructure; first reported in Langerhans' cells of the epidermis. Synonym: Birbeck's granule. (05 Mar 2000) |
| Langerhans' islands | <anatomy> Groups of cells found within the pancreas: A cells and B-cells secrete insulin and glucagon. See: D cells. (18 Nov 1997) |
| Langerhans, Paul | <person> B. Berlin, July 25th, 1847. Was a Physician and an Anatomist and became Professor of Pathological Anatomy in Freiburg. On his retirement went to Madeira. D. Funchal, July 20th, 1888. Islets of Langerhans - collection of cells in the pancreas which produce insulin and glucagon. Cells of Langerhans - dendritic cells found in the epidermis of the skin. Lived: 1847-1888. (05 Dec 1998) |
| malignant histiocytosis | A rapidly fatal form of lymphoma, characterised by fever, jaundice, pancytopenia, and enlargement of the liver, spleen, and lymph nodes; the affected organs show focal necrosis and haemorrhage, with proliferation of histiocytes and phagocytosis of red blood cells. (05 Mar 2000) |
| regressing atypical histiocytosis | A rare disease characterised clinically by multiple ulcerating cutaneous papules and nodules which show spontaneous regression; the skin is infiltrated by malignant-appearing histiocytes. (05 Mar 2000) |
| histiocytosis | A condition marked by the abnormal appearance of histiocytes (macrophages) in the blood. Lipid h., Niemann-Pick disease. Sinus h., a disorder of the lymph nodes in which the distended sinuses are completely or nearly completely, filled by histiocytes, as a result of active multiplication of the littoral cells. H. X, a generic term embracing eosinophilic granuloma, Letterer-Siwe disease and Hand-Schuller-Christian disease and indicating a shared common origin for the three entities. (16 Dec 1997) |
