The t(10;11)(p12-14;q14-21) is a non-random translocation that results in the fusion of CALM gene on chromosome 11 with AF10 gene on chromosome 10. This translocation is observed in acute myeloid leukemia, acute lymphoblastic leukemia, and lymphoblastic lymphoma. Here we report a patient with t(10;11) who was diagnosed with AML-M4. Reverse transcriptase-polymerase chain reaction (RT-PCR) assay revealed one type of CALM/AF10 and three types of AF10/CALM fusion transcripts. Sequencing analysis for these RT-PCR products determined the breakpoint in CALM at nucleotide (nt) 1926-1927 and in AF10 at nt 423-424. The latter breakpoint was the same as that identified in three monocytic cell lines carrying t(10;11). After achieving complete remission, the patient developed mediastinal emphysema during the course of consolidation therapy, possibly due to the necrosis of his mediastinal mass. Monocytic leukemias with CALM/AF10 fusion are frequently associated with mediastinal invasion. We need to pay special attention to such a complication, even if the chest X-ray is normal at presentation.

We reported 5 patients who developed air-leak syndrome (ALS) including pneumothorax, pneumomediastinum and subcutaneous emphysema after allogeneic stem cell transplantation (SCT). The underlying diseases were AML (n=2), ALL (n=1), MDS (n=1), and CML (n=1). All patients received allogeneic SCT from related donors including 2 donors with HLA mismatch. Total body irradiation was performed as a conditioning regimen in all patients. Late-onset noninfectious pulmonary complications (LONIPC) were detected in all patients before the development of ALS. The interval from diagnosis of LONIPC to onset of ALS was 10-360 days (median, 20 days). Four of 5 patients were treated with corticosteroid for chronic graft-versus-host disease and/or LONIPC. To date, three patients have died of respiratory failure. The others are currently alive and one of these surviving patients is receiving home oxygen treatment. Physicians should be aware of this rare complication following LONIPC, because treatment of ALS is difficult in some patients.
