lymphoma
Chapter: 4
A malignant neoplasm arising in lymphoid cells. It normally causes lymph node swelling, since the lymph nodes are where most lymphoid tissue resides. However, lymphoma may arise anywhere there are lymphocytes, which is to say that it may arise anywhere. During the recent HIV epidemic, we have begun to see more lymphomas arising in the gastrointestinal tract amongst the Gut-associated lymphoid tissue (GALT). Some clinicians have called these malignancies GALTomas. We have also seen an increase in lymphomas arising in the central nervous system in those patients infected with the HIV.
