Chromosome 14 is the most frequently rearranged chromosome in non-Hodgkin lymphoma (NHL), with aberrations particularly involving the heavy-chain immunoglobulin gene (IGH) in the chromosome band 14q32. Several translocation partners have been described: t(14;18)(q32;21)/IGH-BCL2 in follicular lymphoma (FL), t(11;14)(q13;q32)/CCND1-IGH in mantle cell lymphoma, and t(8;14)(q24;q32)/MYC-IGH in Burkitt lymphoma. The chromosomal locus 22q11 contains two important genes associated with leukemia and lymphoma; one is BCR, which fuses with ABL from 9q34 in chronic myeloid leukemia, and the other is the immunoglobulin lambda gene (IGL), which is rarely involved in the translocations observed in B-cell NHL. The t(14;22)(q32;q11) translocation has been previously reported in 8 cases of B-cell NHL; however, the translocation between IGH and IGL has been experimentally confirmed using fluorescence in situ hybridization (FISH) for only 4 cases. Here, we describe the first case of FL with a t(14;22)(q32;q11)/IGH-IGL translocation confirmed using FISH analysis. The patient in our case report was immunocompromised and was treated for aplastic anemia with cyclosporine A (CsA). The patient was diagnosed with follicular lymphoma, most likely caused by CsA.
