Rebound peripheral blastosis with subsequent remission during remission induction in a patient with acute promyelocytic leukemia.
A patient with acute promyelocytic leukemia manifested peripheral blastosis with 50% peripheral blasts and an absolute blast count of 10,000/microliter 2 weeks after the start of induction chemotherapy. The subsequent disappearance of the peripheral and marrow blasts without further chemotherapy was noticed, and complete remission was achieved on day 25 of chemotherapy. The histologic and clinical implications of this phenomenon are discussed.
