LymphomaJAMA Cancer of the lymphoid tissues. Lymphomas are often described as being large or small cell types, cleaved or noncleaved, diffuse or nodular. The different types often have different prognoses (ie, prospect of survival or recovery). Some of these lymphomas are named after the physicians who first described them (eg, Burkitt's lymphoma, Hodgkin's disease). Lymphomas also can be referred to by the organ where they are active, such as CNS lymphomas, which are in the central nervous system, and GI lymphomas, which are in the gastrointestinal tract. The types of lymphomas most commonly associated with HIV infection are called non-Hodgkin's lymphomas or B-cell lymphomas. In these types of cancers, certain cells of the lymphatic system grow abnormally. They divide rapidly, growing into tumors.
a malignant disease (cancer) of the lymphoid tissue.
Lymphoma is common in HIV positive people with fewer that 50 CD4 cells/mm3.
Lymphoma may spread out of the lymph nodes (extranodal disease) and into
the brain, bone marrow or liver; primary central nervous system lymphoma
originates in the brain. Symptoms include swollen lymph nodes, weight
loss and fever. Lymphomas are classified as Hodgkins disease or non-Hodgkins
