i believe you mean lymphnodes. They are small blood filters. Lymphocytes are a kind of white blood cell, also known as a helper-T cell. They are small but mighty, just as any other blood cell!
There are many diseases which destroy lymphocytes. You are most likely thinking of HIV infection though. HIV (human immunodeficiency virus) specifically enters CD4 T cells, a specific type of lymphocyte also known as helper T cell. It reproduces inside these cells and ultimately destroys them, slowly depleting the person of all of their CD4 T cells. This leads to acquired immunodeficiency syndrome (AIDS).
