| lymphoma, lymphoblastic | A high-grade malignant lymphoma composed of a diffuse, relatively uniform proliferation of cells with round or convoluted nuclei and scanty cytoplasm. The cells are cytologically similar to the lymphoblasts seen in acute lymphocytic leukaemia, and in some cases, the disease may evolve into a leukaemic phase morphologically indistinguishable from acute t-lymphocytic leukaemia (leukaemia, T-cell, acute). Lymphoblastic lymphoma represents approximately one-third of the cases of non-hodgkin's lymphomas in children and 5% of the cases in adults. It is more prevalent in males. (12 Dec 1998) |
|---|---|
| lymphoma, mixed-cell | Malignant lymphoma characterised by the presence of a mixed population of cells, with the smaller cells resembling lymphocytes and the larger ones histiocytes. It usually presents in a nodular (follicular) pattern, but may evolve into a diffuse pattern. (12 Dec 1998) |
| lymphoma, mixed-cell, diffuse | A heterogeneous group of intermediate-grade lymphomas of mixed cellular composition. Although they have not been extensively studied, it appears that they are predominantly B-cell diseases. (12 Dec 1998) |
| lymphoma, mixed-cell, follicular | A low-grade malignant lymphoma of follicular pattern in which there is no clear preponderance of one cell type (small or large) over another. The large cells, cleaved or noncleaved, are often 2-3 times larger in diameter than normal lymphocytes. (12 Dec 1998) |
| lymphoma, mucosa-associated lymphoid tissue | Extranodal lymphoma of lymphoid tissue associated with mucosa that is in contact with exogenous antigens. Many of the sites of these lymphomas, such as the stomach, salivary gland, and thyroid, are normally devoid of lymphoid tissue. They acquire malt tissue as a result of an immunologically mediated disorder. (12 Dec 1998) |
| lymphoma, non-hodgkin | Any of a group of malignant tumours of lymphoid tissue that differ from hodgkin disease, being more heterogeneous with respect to malignant cell lineage, clinical course, prognosis, and therapy. The only common feature among these tumours is the absence of giant reed-sternberg cells, a characteristic of hodgkin's disease. (12 Dec 1998) |
| 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, small-cell | A B-cell lymphoma presumably representing a tumour of interfollicular B-lymphocytes that may be functional. Those that are secrete identical immunoglobulin molecules. (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) |

| Lycoperdon |
The puffball is a fungus that consists of a polyphyletic assemblage of Basidiomycota with gasterothecia (gasteroid basidiocarps) in which the spores are produced internally; that is, the basidiocarp remains closed, or opens only after the spores have been released from the basidia. The spores of puffballs are statismospores rather than ballistospores, meaning they are not actively shot off the basidium. ...

| Lycoris |
Lycoris, formerly Redmond Linux Corp, was started in the year 2000 with a vision of making free software easy enough for anyone to use. Redmond Linux was founded by Joseph Cheek, an entrepreneur who had previously worked for both Microsoft and Linuxcare. In late 2001 it merged with embedded systems company DeepLinux; the merged entity was named Redmond Linux Corporation. The company's first product was Redmond Linux Personal, an easy-to-use Linux desktop operating system. ...

| lymphatic |
In mammals including humans, the lymphatic vessels (or lymphatics) are a network of thin tubes that branch, like blood vessels, into tissues throughout the body. Lymphatic vessels carry lymph, a colorless, watery fluid originating from interstitial fluid (fluid in the tissues). The lymphatic system transports infection-fighting cells called lymphocytes, is involved in the removal of foreign matter and cell debris by phagocytes and is part of the body's immune system. ...
