angioimmunoblastic lymphadenopathy with dysproteinemia

angioimmunoblastic lymphadenopathy with dysproteinemia (AILD),

a systemic disorder resembling lymphoma, characterized by fever, night sweats, weight loss, and generalized lymphadenopathy. There are cellular infiltration of lymphocytes, immunoblasts, and plasma cells; change or effacement of lymph node architecture; hepatosplenomegaly; maculopapular rash; polyclonal hypergammaglobulinemia; and Coombs' positive hemolytic anemia. It is considered to be a nonmalignant hyperimmune reaction to chronic antigenic stimulation. There are proliferation of B cells and profound deficiency of T cells. The disease follows a progressive but variable course; some patients have long survival without chemotherapy, whereas others have a rapid course, with death from overwhelming infection.

angioimmunoblastic lymphadenopathy (angioimmunoblastic lymphadenopathy with dysproteinemia (AILD)) a systemic disorder resembling lymphoma characterized by fever, night sweats, weight loss, generalized lymphadenopathy, hepatosplenomegaly, macropapular rash, polyclonal hypergammaglobulinemia, and Coombs'-positive hemolytic anemia. It is considered to be a nonmalignant hyperimmune reaction to chronic antigenic stimulation; there is proliferation of B cells accompanied by profound deficiency of T cells. The disease follows a progressive but extremely variable course: some patients survive for a long period without chemotherapy; in other patients, overwhelming infections rapidly lead to death

dermatopathic lymphadenopathy regional lymph node enlargement associated with melanoderma and other dermatoses marked by chronic erythroderma.

lymphadenopathy syndrome a condition occurring in immunocompromised individuals, characterized by unexplained lymphadenopathy for 3 or more months that involves extrainguinal sites, which on biopsy reveal nonspecific lymphoid hyperplasia. See also AIDS-related complex.
