Pulmonary involvement in angio-immunoblastic lymphadenopathy (A.I.L.D.). Case report and review of literature

Abstract

A.I.L.D. is a hyperimmune disorder of the B-cell system of unknown etiology. Although it is distinguished morphologically from Hodgkin's disease, the clinical manifestations may be similar. Pulmonary localisation of A.I.L.D. is infrequently seen. We report the radiologic and pathologic findings of a pulmonary localisation of A.I.L.D. The infiltrates were first localised in the interstitium, developing into complete consolidation of the lung bases. It is important to remember that although superimposed infection is a frequent complication, specific interstitial infiltration may occur and is often fatal.
