Abstract
A patient who developed an immunoblastic leukemia of T-cell type two and one-half years after initial diagnosis of mixed cellularity Hodgkin's disease, stage IIIB, is described. The patient's course was characterized by an initial 15-month remission following radiation therapy. A relapse of Hodgkin's disease was treated with intensive chemotherapy. Thirteen months later the patient entered a rapid terminal course with multiple organ infiltrates and a leukemic peripheral blood. The leukemic phase was characterized by a 55,000 WBC with 48% immunoblasts, greater than 90% of which marked as T-cells. Although acute myelogenous leukemia, acute lymphocytic leukemia, lymphosarcoma cell leukemia and other tumors have been described in Hodgkin's disease after intensive therapy, this is the first report of the unusual association of a T-cell immunoblastic leukemia with Hodgkin's disease.
