MALT1 and MALT lymphoma: Cytogenetic analyses using G-banding, reverse-transcription polymerase chain reaction (RT-PCR), and/or fluorescence in situ hybridization (FISH) to detect t(11;18) (q21;q21)/BIRC3-MALT1 and/or other specific chromosomal translocations can be performed to confirm the certain diagnosis of MALT lymphoma [2,3,19,20,21,22].
