Lymphadenopathy mimicking lymphoma associated with cryoglobulinaemia and arteritis.
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.
