| 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) |
|---|---|
| histiocytosis x | 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) |
| histiocytosis Y | A papilloma of the oral mucosa and skin in which squamous epithelium covers connective tissue papillae filled with large foamy histiocytes. Synonym: histiocytosis Y. (05 Mar 2000) |
| 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, malignant | A rare, usually rapidly progressive disorder, characterised by abrupt onset, fever, weight loss, hepato-splenomegaly, pancytopenia, and lymphadenopathy. (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) |
| histiocytosis, sinus | Benign, non-langerhans-cell, histiocytic proliferative disorder that primarily affects the lymph nodes. It is often referred to as sinus histiocytosis with massive lymphadenopathy. (12 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) |
| sinus 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) |
| sinus histiocytosis with massive lymphadenopathy | A chronic disease occurring in children and characterised by massive painless cervical lymphadenopathy due to distension of the lymphatic sinuses by macrophages containing ingested lymphocytes, and by capsular and pericapsular fibrosis. Synonym: Rosai-Dorman disease. (05 Mar 2000) |
| nodular non-X histiocytosis | A rare recurring generalised eruption in adults of flesh coloured or erythematous papules remaining localised to the skin and consisting of dermal nodules of mononuclear histiocytes that do not stain for lipid. Synonym: nodular non-X histiocytosis. (05 Mar 2000) |
| nonlipid histiocytosis | histiocytosis |
| lipid histiocytosis | Histiocytosis with cytoplasmic accumulation of lipid, either phospholipid (Niemann-Pick disease) or glucocerebroside (Gaucher's disease). (05 Mar 2000) |
