| lymphocytic adenohypophysitis | A diffuse lymphocytic infiltration of the adenohypophysis, often related to pregnancy; probably a disturbance in the immune system. (05 Mar 2000) |

| lymphocytic choriomeningitis | A form of viral meningitis caused by the lymphocytic choriomeningitis virus. In humans it may be inapparent or present with symptoms of a flu-like disease, aseptic meningitis, encephalitis, or myelitis. (12 Dec 1998) |
| lymphocytic choriomeningitis virus | The type species of arenavirus, part of the lcm-lassa complex viruses, producing an inapparent infection in house and laboratory mice. In humans, infection with lcmv can be inapparent, or can present with an influenza-like illness, a benign aseptic meningitis, or a severe meningoencephalomyelitis. The virus can also infect monkeys, dogs, field mice, guinea pigs, and hamsters, the latter an epidemiologically important host. (12 Dec 1998) |
| lymphocytic interstitial pneumonia | A rare disease characterised by interstitial accumulation of lymphocytes in the lungs and late fibrosis; usually a result of a lymphoma, occasionally seen in AIDS, especially. In children. Sometimes seen as an autoimmune disorder. Synonym: lymphocytic interstitial pneumonia, lymphoid interstitial pneumonia. (05 Mar 2000) |
| lymphocytic interstitial pneumonitis | A rare disease characterised by interstitial accumulation of lymphocytes in the lungs and late fibrosis; usually a result of a lymphoma, occasionally seen in AIDS, especially. In children. Sometimes seen as an autoimmune disorder. Synonym: lymphocytic interstitial pneumonia, lymphoid interstitial pneumonia. (05 Mar 2000) |
| lymphocytic leukaemia | <haematology, oncology> An acute form of childhood leukaemia characterised by the development of abnormal cellsdevelop in the bone marrow and lymphoblasts are found in blood-formingtissues. A type of chronic leukaemia found most often in the elderly, it is characterised by the presence of mature lymphocytes in the blood. Origin: Gr. Haima = blood (13 Nov 1997) |
| lymphocytic leukemoid reaction | Leukocytosis of varying degree, with adult lymphocytes and immature forms amounting to 40% (or more) of the total number of white blood cells in the circulating blood; may be observed in association with pertussis, infectious mononucleosis, gonorrhoea, chickenpox, and sarcoidosis. (05 Mar 2000) |
| lymphocytic leukocytosis | A condition in which the blood contains an unusually high number of normal lymphocytes. (09 Oct 1997) |
| lymphocytic leukopenia | Reduction in the number of lymphocytes. (12 Dec 1998) |
| lymphocytic lymphoma | <oncology, tumour> A cancer of lymphatic tissues, the tumour cells are mostly abnormal lymphocytes. (13 Nov 1997) |
| lymphoma, small lymphocytic | A low-grade malignant lymphoma that may, in some cases, be considered histologically identical to chronic lymphocytic leukaemia (cll; leukaemia, lymphocytic, chronic). It is diffuse in pattern, representing the neoplastic proliferation of well-differentiated B-lymphocytes. In patients with immunoglobulin gammopathies, the lymphocytes may exhibit plasmacytoid characteristics. (12 Dec 1998) |
| autoimmune thyroiditis | <endocrinology> Inflammation of the thyroid gland without the formation of pus. Noninfectious nonbacterial thyroid inflammation. (27 Sep 1997) |
| parasitic thyroiditis | Chronic South American trypanosomiasis with involvement of the thyroid gland, causing myxoedema. (05 Mar 2000) |
| giant cell thyroiditis | Thyroiditis with round cell (usually lymphocytes) infiltration, destruction of thyroid cells, epithelial giant cell proliferation, and evidence of regeneration; thought by some to be a reflection of a systemic infection and not an example of true chronic thyroiditis. Synonym: de Quervain's thyroiditis, giant cell thyroiditis. (05 Mar 2000) |
| giant follicular thyroiditis | A variant of Hashimoto's thyroiditis in which lymphocytic infiltrate in thyroid has formed into giant follicles. (05 Mar 2000) |
