Philadelphia Chromosome Positive de novo Acute Myeloid Leukemia.

Philadelphia chromosome positive de novoacute myeloid leukemia (AML)is a rare disease with reported incidence of less than 1% of newly diagnosed cases of AML. Outcome of the disease is poor, owing to its resistance to conventional chemotherapy and variable response to imatinib besylate. We report a case of 24-year man who reported to our unit in November 2014 and was treated with conventional induction and consolidation chemotherapy with imatinib besylate. He achieved complete remission after induction chemotherapy and remained in remission. His cytogenetics also reverted to normal after consolidation chemotherapy. He relapsed after 3 months of maintenance imatinib besylate.
