Angio-immunoblastic lymphadenopathy. Diagnosis and clinical course.
Abstract
The clinical and pathologic findings in 24 patients with "angio-immunoblastic lymphadenopathy with dysproteinemia" (AILD) are presented. The patients' ages ranged from 44 to 80 years, with a median age of 68 years. The disease has an acute onset. In many respects, the clinical presentation is suggestive of malignant lymphoma. Generalized lymphadenopathy was always present. Hepatomegaly was found in 20 patients, splenomegaly in 17, constitutional symptoms in 20 and skin rashes in nine. Twenty patients had anemia, with positive Coombs' test in eight of 14 tested. Polyclonal hypergammaglobulinemia was found in 17 of 22 patients. Two patterns of evolution were recognizable: (1) long survival (24 to 67 months) without treatment or after the administration of intensive combination chemotherapy; and (2) rapid progression (one to 19 months) regardless of the treatment given. Sixteen patients died; postmortem examination in 10 cases showed the cause of death to be attributable to severe infection in eight patients, to renal disease in one and to cardiovascular disease in one. No evidence of malignant lymphoma was seen in any of these autopsies. Histologically, the disease is systemic, with specific lesions in the lymph nodes. The spleen...Continue Reading
