Thymic Extranodal Marginal Zone Lymphoma of Mucosa-associated Lymphoid Tissue with 8q24 Abnormality.

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) of the thymus is reported to have characteristic features that distinguish it from MALT lymphoma of other organs; it is proposed to be a distinct clinicopathological subgroup of MALT lymphoma. We herein present a case of thymic MALT lymphoma accompanied by Sjögren's syndrome, involving the first report of a thymic MALT lymphoma patient carrying a chromosomal abnormality of 8q24. No c-myc gene translocation or c-Myc protein overexpression was observed, suggesting that c-myc was not involved in lymphomagenesis or progression.

[Efficacy of serum immunoglobulin free light chain and 18F-FDG PET/CT for therapeutic evaluation in a case with multiple plasmacytoma of bone].

Solitary/multiple plasmacytoma of bone, a rare disease as compared to multiple myeloma, is characterized by monoclonal proliferation of plasma cells in local legion (s) of bone, with no bone marrow abnormalities. Monoclonal gammagloblinemia is often absent in these conditions, and useful examinations allowing evaluation of responses to treatment are as yet lacking. Recently, 18F-FDG PET/CT (PET/CT) was reported to be useful for detecting bone lesions.

The association of level of reduction of Wilms' tumor gene 1 mRNA transcript in bone marrow and outcome in acute myeloid leukemia patients.

We focused on the level of reduction of Wilms' tumor gene 1 (WT1) mRNA in bone marrow as minimal residual disease during chemotherapies in adult acute myeloid leukemia (AML) patients. Forty-eight patients were enrolled in this study. Log levels of reduction of WT1 mRNA transcript after induction therapy compared with those at diagnosis were associated with disease-free survival (DFS) (P=0.

IL-6-positive classical Hodgkin's lymphoma co-occurring with plasma cell type of Castleman's disease: report of a case.

We present a case of classical Hodgkin's lymphoma (HL) co-occurring with histological features of Castleman's disease (CD). A 25-year-old man presented with left supraclavicular and axillary lymph node swelling and mediastinal mass. Using an initial biopsy specimen from left axillary lymph node, a tentative diagnosis of multicentric CD of plasma cell type was made.

Clinical value of assessing the response to imatinib monitored by interphase FISH and RQ-PCR for BCR-ABL in peripheral blood for long-term survival of chronic phase CML patients: results of the Niigata CML-multi-institutional co-operative clinical study.

This retrospective analysis investigated the prognostic value of monitoring the response to imatinib using peripheral blood (PB) samples and the impact of the response on outcome in 133 patients with chronic myeloid leukemia (CML). We divided the response into 3 categories according to the results of neutrophil (N)-FISH and BCR-ABL transcript levels in PB; more than a 3-log reduction [major molecular response (MMR)], between a 2-log and 3-log reduction or negative with N-FISH [complete cytogenetic response equivalent (CCyRe)], N-FISH positive or less than a 2-log reduction (non-CCyRe). The median follow-up was 5.

Sequential adenovirus infection of type 14 hemorrhagic cystitis and type 35 generalized infection after cord blood transplantation.

We report a case of a 29-year-old male patient with a generalized adenovirus (AdV) infection after cord blood transplantation (CBT) for acute myelocytic leukemia with maturation at 2nd complete remission. Before engraftment, hemorrhagic cystitis was caused by AdV, which resulted in hydronephrosis, renal failure, and adenoviremia on day 34. Forced diuresis, hemodialysis, withdrawal of cyclosporin A, and administration of gamma-globulin or vidarabine were not effective and the patient died of pulmonary alveolar hemorrhage on day 67.
