Abstract
We report a rare case of adult Philadelphia chromosome (Ph)-positive acute lymphoblastic leukemia (ALL) with an e1a3 fusion transcript. A 25-year-old female consulted our hospital for leukocytosis and thrombocytopenia. She was diagnosed with Ph-positive precursor B cell ALL. The patient’s BCR–ABL fusion gene showed the e1a3 transcript. She received bone marrow transplantation (BMT) in the first complete remission (CR). However, the disease relapsed 4 months later, and she received a second BMT in the second CR, which caused lethal venoocculusive disease. The duration of the total clinical course was 18 months. We established a new cell line from the patient’s leukemic cells at the time of relapse, which is very rare and useful for study as an atypical Ph-positive ALL model. The literature on Ph-positive leukemia lacking ABL exon 2 was also reviewed.
