BACKGROUND It remains unknown whether primary ocular adnexal extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is a homogeneous entity, as there are few reports of the results of cytogenetic or molecular analyses of these tumors. METHODS We performed interphase fluorescence in situ hybridization (FISH) analysis(More)
Amplification and translocation of the Bcl-2 gene has been detected in a certain subset of diffuse large B-cell lymphomas (DLBCL). The correlations among Bcl-2 protein expression, gene translocation or amplification, and the molecular signature determined by cDNA array are poorly understood. This study examined 25 cases with de novo nodal DLBCL. Interphase(More)
The frequency of t(14;18) in follicular lymphoma (FL) in Japan has been reported to be low compared to North America and other European countries. Recently, it has also been reported that FL lacks t(14;18), mainly among histological grade 3b, and occasionally has a rearranged Bcl-6 gene. It is not known whether a difference in histology or immunostaining(More)
Posttransplantation lymphoproliferative disorder (PTLD) is one of the well-recognized complications after allogeneic stem cell transplantation (SCT). It generally occurs early after SCT, and only a few reports of late-onset cases are available. We report a 58-year-old male patient who developed lymphoma 4 years after allogeneic SCT for chronic myeloid(More)
We studied the prevention of phlebitis in 10 patients who had developed the symptoms after receiving vinorelbine to treat breast cancer at our outpatient chemotherapy clinic from July 2005 to August 2006. Veins proximal to the injection site were warmed using hot compresses during the vinorelbine injection and physiological saline was increased to wash out(More)
Mucosa-associated lymphoid tissue (MALT) lymphoma is a low-grade B-cell lymphoma and is usually slow to disseminate. The t(11;18)(q21;q21) translocation has been identified in a subset of MALT lymphoma cases, and AP12 and MLT1/MALT1 genes have been implicated in this translocation. However, the clinicopathologic features of t(11;18)-bearing MALT lymphoma(More)
Primary granulocytic sarcoma (GS) is a rare disease defined by the absence of antecedent or concomitant leukemic cells in the bone marrow and the peripheral blood. Immunohistochemical staining for myeloperoxidase is necessary for a definite diagnosis. Otherwise, primary GS is often misdiagnosed as a malignant lymphoma or other malignancies. Primary GS is(More)
