title: Immunoblastic lymphadenopathy. A report of two cases.
abstract: Two patients with immunoblastic lymphadenopathy had lymphadenopathy, hepatosplenomegaly, rash, dysproteinemia, constitutional symptoms, and typical morphologic findings or lymph node obliteration by immunoblasts and plasma cells, proliferation of aborizing vessels, and infiltration with amorphous, eosinophilic material. One patient had massive pulmonary infiltrates that responded to steroid therapy early in the course of the disease, but recurred and were found, at autopsy, to represent immunoblastic invasion of the lung. In both cases, a severe peripheral neuropathy developed during the course of the disease. One patient was addicted to dextroamphetamine for 20 years. Response to corticosteroids and cytotoxic therapy was initially rapid and complete, but refractoriness developed as seen in postmortem findings of extensive visceral involvement.
