[Polyneuropathy and dysglobulinemia presenting 36 months before an angio-immunoblastic lymphadenopathy (author's transl)].

We report a patient with angio-immunoblastic lymphadenopathy (A.I.L.) with pulmonary localisation. The symptomatology of the A.I.L. was dominated by a polyclonal increase in gammaglobulins and a neuropathy 35 months before the generalized lymphadenopathy. We discuss this unusually long prodromal period and the nature of the neuropathy.
