In the FISH results, 9 cases (39.1%, 9/23) showed API2-MALT1 fusion gene, 1 case with possible BCL10-IgH abnormality, but none showed chromosomal abnormalities related with MALT1 and IgH gene simultaneously.     ///    "BCL10 was detected by immunohistochemistry of EnVision method, and API2-MALT1, BCL10, MALT1, IgH chromosomal abnormalities were detected by fluorescent in situ hybridization (FISH) technique.
