Chronic relapsing neuropathy associated with Castleman's disease (angiofollicular lymph node hyperplasia).

We report a 17-year-old patient who presented a chronic relapsing sensorimotor demyelinating neuropathy with 6 relapses over a 7-year period, preceding by 4 years the diagnosis of a multicentric angiofollicular lymph node hyperplasia. A role for Epstein-Barr virus (EBV) as a trigger of the neuropathy may be suggested by the presence of EBV DNA in the biopsied abdominal abdominal adenopathies. This unusual reported association seems to have a better prognosis than the known chronic progressive form of neuropathy associated with Castleman's disease and the Crow-Fukase syndrome.
