Angioimmunoblastic lymphadenopathy (AILD) may respond to thalidomide treatment: two case reports.

The histological morphology of AILD-type T-cell lymphoma shows proliferation of small, arborizing high endothelial venules. Patients typically have generalized lymphadenopathy, fever, weight loss, skin rash, polyclonal hypergammaglobulinemia and autoimmune phenomena, and are susceptible to infections. The clinical course is usually aggressive. About 30% of patients have an initial remission on steroids alone, but most require some form of cytotoxic chemotherapy. Median survival ranges from 15 to 24 months, and it appears that the disease cannot be cured. We have used anti-angiogenetic therapy with thalidomide in two AILD patients and observed remarkable responses.
