title: Peripheral neuropathy associated with angioimmunoblastic lymphadenopathy.
abstract: A 49-year-old man developed mononeuritis multiplex associated with angioimmunoblastic lymphadenopathy. The biopsy of the sural nerve revealed focal reduction of myelinated fibres and axonal degeneration, as well as perivascular inflammatory infiltrates composed of lymphocytes and plasma cells, exhibiting policlonal immunoglobulin expression, proliferation of blood vessels, thickening of the vessel wall and endothelial hyperplasia. These latter changes are similar to those commonly encountered in the lymph nodes, as well as in other organs, in patients suffering from angioimmunoblastic lymphadenopathy.
