title: Lymphadenopathy mimicking lymphoma associated with cryoglobulinaemia and arteritis.
abstract: Two patients are described with polyclonal IgG cryoglobulinaemia and necrotizing arteritis who developed severe lymphadenopathy which clinically mimicked malignant lymphoma. Histological studies demonstrated that the lymphadenopathy resulted from a pseudolymphomatous reaction associated with vascular damage.
