| lymphoma, small cleaved-cell, diffuse | An intermediate-grade malignant lymphoma in which the neoplastic cells (B-lymphocytes) exhibit variability in size, configuration, and degree of differentiation. The cells have distinctive nuclei, irregular in shape, with marked indentations and angularity. (12 Dec 1998) |
|---|---|
| lymphoma, small cleaved-cell, follicular | A low-grade malignant lymphoma of predominantly follicular pattern. Follicles are of relatively uniform size and shape and the cells are usually somewhat larger than normal lymphocytes. Nuclei are irregular with prominent indentations and cytoplasm can rarely be identified. Cells exhibiting these characteristics are often called centrocytes. (12 Dec 1998) |
| 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) |
| lymphoma, small noncleaved-cell | A high-grade malignant lymphoma that includes both burkitt tumour (burkitt lymphoma) and other lymphomas previously designated undifferentiated non-burkitt type. Nuclei in burkitt tumour are round to ovoid and uniform in size. The non-burkitt type exhibits greater nuclear variation and less evidence of cellular maturation with a correspondingly lesser degree of differentiation. (12 Dec 1998) |
| lymphoma, T-cell | A group of heterogeneous lymphoid tumours representing malignant transformations of T-lymphocytes. (12 Dec 1998) |
| lymphoma, T-cell, cutaneous | A group of lymphomas exhibiting clonal expansion of malignant T-lymphocytes arrested at varying stages of differentiation as well as malignant infiltration of the skin. Mycosis fungoides and sezary syndrome are the best characterised of these disorders. (12 Dec 1998) |
| lymphoma, T-cell, peripheral | A group of malignant lymphomas thought to derive from peripheral T-lymphocytes in lymph nodes and other nonlymphoid sites. They include a broad spectrum of lymphocyte morphology, but in all instances express T-cell markers admixed with epithelioid histiocytes, plasma cells, and eosinophils. Although markedly similar to large-cell immunoblastic lymphoma (lymphoma, large-cell, immunoblastic), this group's unique features warrant separate treatment. (12 Dec 1998) |
| lymphoma, undifferentiated | A form of lymphoma in which relatively large stem cells with large nuclei, pale, scanty cytoplasm, and indistinct borders are predominant. The cells are undifferentiated, i.e., show no morphologic evidence of maturation toward lymphocytes or histiocytes. (12 Dec 1998) |
| adenoviruses, human | Species of the genus mastadenovirus, causing a wide range of diseases in humans. Infections are mostly asymptomatic, but can be associated with diseases of the respiratory, ocular, and gastrointestinal systems. (12 Dec 1998) |
| adenovirus infections, human | Respiratory and conjunctival infections caused by 33 identified serotypes of human adenoviruses. (12 Dec 1998) |
| antigens, human platelet | Human alloantigens expressed only on platelets, specifically on platelet membrane glycoproteins. These platelet-specific antigens are immunogenic and can result in pathological reactions to transfusion therapy. (12 Dec 1998) |
| bites, human | Bites inflicted by humans. (12 Dec 1998) |
| bonding, human-pet | The emotional attachment of individuals to pets. (12 Dec 1998) |
| packed human blood cells | Whole blood from which plasma has been removed; may be prepared any time during the dating period of the whole blood from which it is derived, but not later than six days after the blood has been drawn if separation of plasma and cell's is achieved by centrifugation. (05 Mar 2000) |
| genetic human male | An individual with a karyotype containing a Y chromosome, an individual whose cell nuclei do not contain Barr sex chromatin bodies, which are normally present in females. Patients with ambiguous sexual development and those with Turner's syndrome are classed as genetic male's or genetic females according to the absence or presence of Barr bodies even though their sex chromosome complement may suggest otherwise.
