Abstract
We describe two follicular lymphoma (FL) patients with MYC/BCL2 double- and MYC/BCL2/BCL6 triple-hit translocations. The first patient (case 1) was a man in his 30s who presented with stage IV disease with leukemic manifestation. The second patient (case 2) was a man in his 60s who presented with relapsed FL, but his disease was in a limited stage. Histopathology of the lymph node biopsies revealed grade 3A FL in both cases. MYC positivity and the Ki-67-labeling index were 60-70 and 20% in case 1 and 30 and 50% in case 2, respectively. G-banding revealed t(8;14;18)(q24;q32;q21) in both cases and fluorescence in situ hybridization using MYC, IGH, and BCL2 break-apart probes confirmed t(8;14;18)(+5'BCL2,-3'MYC;+3'MYC,-5'IGH;+5'IGH,-5'BCL2). In case 2, additional materials of der(8)t(8;14;18) were duplicated and translocated to chromosome Y, and t(3;16)(q27;p13)/BCL6::CIITA was identified. We obtained BCL2-major breakpoint region::IGHJ5::IGHG1 and MYC exon 2::IGHA2 fusion sequences by long-distance polymerase chain reaction in case 1, and proposed that t(8;14;18) was generated by two-step translocations and that BCL2::IGH and MYC::IGH involved the same IGH allele. Both patients responded to the standard chemotherapy for FL. We suggest that the presence of t(8;14;18) in FL does not immediately indicate high-grade transformation and aggressive clinical behavior requiring intensive chemotherapy.

Abstract
We describe two patients with primary diffuse large B-cell lymphoma of the central nervous system (PCNS-DLBCL). The first patient (case 1) was a woman in her late 70s who presented with a tumor in the left frontal lobe, whereas the second patient (case 2) was a man in his early 70s who presented with a left frontal lobe tumor associated with intratumoral hemorrhage. The histopathology of the tumor specimen disclosed the proliferation of large cells with centroblastic (case 1) or immunoblastic/plasmablastic (case 2) cytomorphology and an accumulation of the tumor cells within the perivascular space. The cells in both cases were positive for CD20, CD79a, BCL6, IRF4/MUM1, MYC, and BCL2 and negative for CD5 and CD10. G-banding revealed t(8;14)(q24;q32) in case 1, and the tetraploid-range karyotype including two or three copies of der(3)t(3;14)(q27;q32) and der(14)t(3;14)(q27;q32) in case 2. Fluorescence in situ hybridization applied to metaphase spreads confirmed colocalization of MYC and IGH (case 1) and BCL6 and IGH (case 2) hybridization signals on the relevant derivative chromosomes. Case 1 carried the MYD88L265P mutation. This case report provides clear evidence for the occurrence of t(8;14)(q24;q32) and t(3;14)(q27;q32) in PCNS-DLBCL using metaphase-based cytogenetic analysis.

Abstract
A 75-year-old man presented with an ileocecal tumor composed of diffuse proliferation of large cells with immunoblastic morphology. Lymphoma cells were positive for CD20, CD79a, IRF4/MUM1, and BCL2, negative for CD5, CD10, and MYC, and partially positive for BCL6. PAX5 was positive with variable staining intensity among the cell nuclei. The V-D-J sequence of IGH showed the mutated configuration. The G-banding karyotype demonstrated two cytogenetic clones with or without t(9;14)(p13;q32), but the two shared other structural and numerical abnormalities. Fluorescence
in situ
hybridization using
PAX5
and IGH probes confirmed the presence or absence of t(9;14)(p13;q32)/
PAX5
-IGH in each clone. The breakpoints of t(9;14)(p13;q32) were mapped 2,170 bp upstream of the coding region of
PAX5
alternative exon 1B and within the IGHJ6-Eμ enhancer intron of IGH. It is suggested that t(9;14)(p13;q32) in this case was a secondary cytogenetic abnormality and the translocation is not necessarily involved in initial malignant transformation of B-cells but can occur later during the course of diffuse large B-cell lymphoma.

Abstract
A 62-year-old woman, who had a 16-year history of
JAK2V617F-mutated myeloproliferative neoplasm
(MPN), developed Burkitt leukemia (BL) 16 months after treatment with
ruxolitinib to control hydroxyurea-refractory conditions. BL cells were
CD10+, CD19+, CD20−,
CD34−, cytoplasmic CD79a+, and TdT+,
and lacked surface immunoglobulins but expressed the cytoplasmic μ heavy
chain. In the bone marrow, nuclear MYC+ BL cells displaced the MPN
tissues. t(8;14)(q24;q32) occurred at a CG dinucleotide within
MYC exon 1 and at the IGHJ3 segment, and an N-like segment
was inserted at the junction. The V-D-J sequence of the non-translocated IGH
allele had the unmutated configuration. DNA from peripheral blood at a time of
the course of MPN exhibited homozygous JAK2V617F
mutation, while that at BL development included both
JAK2V617F and wild-type DNAs. Although the
association between JAK1/2 inhibitor therapy for MPN and secondary development
of aggressive B-cell neoplasm remains controversial, this report suggests that,
in selected patients, close monitoring of clonal B-cells in the BM is required
before and during treatment with JAK1/2 inhibitors.

Abstract
We described four patients with diffuse large B-cell lymphoma (DLBCL) carrying t(9;14)(p13;q32) that places the PAX5 adjacent to the immunoglobulin heavy chain (IGH) gene. Ages ranged between 63 and 80, and three were female. One developed a nodal disease, and the other three involved extranodal organs. The lymphoma cells were CD10- /BCL6- /MUM1+ in three and CD10+ /BCL6+ /MUM1+ in one. BCL2 was weak or negative. All had t(9;14)(p13;q32), and three had additional 14q32/IGH translocations or +der(14)t(9;14)(p13;q32). Fluorescence in situ hybridization using the PAX5 break-apart probe showed that the locus was disrupted between the 5' and 3' probes or within the 5' probe. Immunohistochemistry (IHC) using a monoclonal antibody against PAX5 showed strong nuclear positivity in all four patients. Cell block IHC of a CD30+ DLBCL cell line, KIS-1, which carried the t(9;14)(p13;q32) and PAX5-IGH fusion gene, reproduced the CD10- /BCL6- /MUM1+ immunophenotype, low-level BCL2, and strong nuclear PAX5. Uniform nuclear positivity of MUM1 in all four cases and KIS-1 cells suggest that these lymphomas arose at a late stage of B-cell differentiation, where expression of PAX5 physiologically becomes downregulated. It is therefore possible that high-level PAX5 resulting from t(9;14)(p13;q32) at this stage of differentiation perturbs the plasma cell differentiation program initiated by PAX5 repression, thereby contributing to the development of a fraction of DLBCL.

Abstract
An 80-year-old man presented with the accumulation of pleural fluid in the right thoracic
cavity. Serum electrophoresis revealed an M-component and immunofixation confirmed IgM/λ.
The level of IgM was 1,526 mg/dL. Imaging studies showed an infiltrative condition of the
ipsilateral lung parenchyma. The fluid contained abundant neoplastic cells with the
morphological and immunophenotypic features of plasma cells, which expressed IgM/λ
monoclonal immunoglobulins on the cell surface and in the cytoplasm. The karyotype was
48,XY,+3,add(9)(p13),+12,add(14)(q32),del(16)(q22),−18,+mar, and a series of fluorescence
in situ hybridization studies demonstrated that the add(14) chromosome
represented der(14)t(14;18)(q32;q21), at which the MALT1-immunoglobulin
heavy-chain (IGH) fusion gene was localized. A long-distance polymerase
chain reaction amplified the fragment encompassing the two genes, showing that the
junction occurred at the J6 segment of IGH and 3.7-kb upstream of the
MALT1 breakpoint cluster. We propose that this case represents an
extreme form of the plasmacytic differentiation of extranodal marginal zone lymphoma that
developed in the lung.

Abstract
We herein report a rare case of acute basophilic leukemia with t(16;21)(p11;q22) generating the FUS‐ERG fusion gene. The basophilic nature of leukemia blasts was demonstrated by cytomorphology, toluidine blue metachromasia, mature basophil‐associated antigen expression, and characteristic granules under electron microscopy. The molecular link between t(16;21)/FUS‐ERG and basophilic differentiation remains unclear.

Abstract
Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) may include the lymphoid blast crisis of chronic myeloid leukemia (CML-BC). We applied fluorescence in situ hybridization (FISH) of the BCR-ABL fusion gene to peripheral blood and/or bone marrow smears to determine whether the fusion was restricted to mononuclear cell nuclei or if segmented cell nuclei representing mature neutrophils also carried the fusion (Seg-FISH). Among 20 patients with Ph+ ALL without a prior diagnosis of CML, 9 were Seg-FISH+ and 11 were Seg-FISH-. Seg-FISH+ cases were characterized by a higher rate of p210-type BCR-ABL transcripts, higher white cell and blast counts, and a higher rate of myeloid and T-lymphoid antigen expression than Seg-FISH- cases, in addition to 'major route' cytogenetic abnormalities associated with CML-BC. Eighteen patients were treated with tyrosine kinase inhibitors (TKIs) either alone or in combination with multiagent chemotherapy, and 7 underwent allogeneic hematopoietic stem cell transplantation. Progression-free and overall survivals were greater in the Seg-FISH+ group than in the Seg-FISH- group. These results suggest that the Seg-FISH+ group represents lymphoid CML-BC that occurs de novo, while the Seg-FISH- represents Ph+ ALL in the strict sense, and the two groups are associated with survival when treated with TKIs or TKI-combined therapy.

Abstract
A 75-year-old woman presented with marked leukocytosis; the white cell count was 143.6 × 10³/μL with 38.6 % monocytes and 13.6 % immature granulocytes, including blasts. Bone marrow (BM) aspirate smears showed >90 % cellularity with hyperplasia of myeloid-lineage cells, 14.6 % monocytes, and 32.1 % blasts. The granulocyte series showed a range of dysplastic morphologies. The rate of peroxidase positivity was 51.5 %. CD36+ cells with monocytic differentiation comprised 64.6 % mononuclear cells. Metaphase spreads obtained from the BM revealed an aneuploid karyotype with -7 and a submetacentric marker chromosome derived from chromosome 2, which was determined to be inv(2)(p23q13) by fluorescence in situ hybridization using the Vysis ALK probe. RAN-binding protein 2 (RANBP2)-ALK fusion mRNA was confirmed by reverse transcriptase-mediated polymerase chain reaction and nucleotide sequencing. High-sensitivity anti-ALK immunohistochemistry of a BM biopsy specimen demonstrated nuclear membrane staining of leukemia cells. As the leukemia showed features of chronic myelomonocytic leukemia, the patient was treated with standard daunorubicin-cytarabine followed by azacitidine, leading to the durable suppression of leukemia progression. These findings suggest that inv(2)(p23q13)/RABBP2-ALK defines a small subset of myeloid leukemia characterized by differentiation to monocytes and sharing features of myelodysplastic syndrome/myeloproliferative neoplasm.

Abstract
Imatinib Mesylate, a specific inhibitor of BCR/ABL tyrosine kinase, was developed as a molecularly targeted drug for the treatment of patients with chronic myelogenous leukemia. We evaluated effectiveness of the drug on cytogenetic response for monitoring residual disease using fluorescence in situ hybridization(FISH), reverse transcription-nested-polymerase chain reaction(RT-nested-PCR) and competitive PCR strategy. Of 9 patients in chronic phase, 7 achieved major cytogenetic response(CR) and 2 achieved minor CR by FISH. In 3 out of 6 patients with complete CR, no BCR/ABL gene was detected by RT-nested-PCR in peripheral blood or bone marrow specimens. Of 4 patients in accelerated phase, 1 achieved complete CR but 3 developed blast crisis. Despite high efficacy of Imatinib, 5 out of 13 patients showed resistance to the drug. To clarify the mechanism of resistance, we have newly developed a method for investigating a point mutation of T315I in tyrosine kinase domain of BCR/ABL gene using RT-PCR restriction digested analysis. None of them showed T315I mutation. The sensitivity of the method was as low as 10 copies of mutant gene. The method is useful for screening the mutation when there are many clinical samples or low copy number of BCR/ABL gene. BCR/ABL value obtained by FISH was of use to predict cytogenetic response when residual disease was above 2 to 3%. Below this level, the routine use of RT-nested-PCR was suffices to monitor minimal residual disease.
