Clinically significant cardiac infiltration in acute leukemia, lymphocytic lymphoma, and plasma cell myeloma

Cardiac infiltration by hematologic neoplasms leading to clinically significant cardiovascular disease is rare. Three such cases are described in this report, and it is suggested that rare manifestations of hematologic neoplasms may become more common in the future since these diseases are more amenable to therapy than heretofore. Cardiac involvement with hematologic neoplasms is of more than academic interest since this complication is likely to respond to radiotherapy.
