A total of 106 trephine biopsy specimens with clinical, laboratory and pathology findings corresponding to chronic myeloproliferative disorders (CMPD) were analyzed to reveal the nature of the lymphoid infiltrate in the bone marrow. Histological investigation in 31 chronic myeloid leukemia (CML), 29 CMPDs not otherwise specified (CMPD-NOS), 28 essential(More)
The malignant potential of colorectal adenomas highly correlates with their pathological characteristics, such as size, histology and grade of dysplasia. Currently, based on these parameters, adenomas are characterized as “non-advanced or advanced” and patient surveillance is adjusted accordingly. The aim of this study was to investigate the correlation(More)
Adenocarcinoma is the most common and heterogeneous type of lung cancer. Pulmonary enteric adenocarcinoma (PEAC) is a recently described, extremely rare primary pulmonary adenocarcinoma variant, which has a histological morphology and immunohistochemical phenotype similar to metastatic colorectal carcinoma (MCC). It was described originally in 1991 by Tsao(More)
Among the 300 peripheral T-cell lymphomas (PTCL) searched for EBV positive non-resting B-cells by EBER in situ hybridization 12 have been identified with various forms of EBV-driven B-cell proliferation. This could be categorized into three major forms. i. In the first form scattered immature, mononuclear B-cells of immuno-, centroblastic type with CD20+.(More)
B-cell chronic lymphocytic leukemia-related genomic changes were analyzed by karyotyping, fluorescence in situ hybridization, and V(H) gene sequencing in a prospective clinical evaluation. The V(H) mutational status correlated with high-risk cytogenetic aberrations while no such relation could be demonstrated for specific VH gene usage (V(3-21) and(More)
DNA-, RNA-, and cell-based methods provide different biologic information for determining the presence of minimal residual disease (MRD). We monitored the responses of patients with pediatric acute lymphoblastic leukemia (pALL) using DNA markers, TEL/AML1 expression, and scanning fluorescence microscopy (SFM). Using SFM, 36% of patients exhibited 1.5-3.1(More)
The authors investigated by reverse transcription-polymerase chain reaction the incidence of the t(12;21)(p13;q22) translocation among 130 pediatric acute lymphoblastic leukemia registered by the Hungarian Pediatric Oncology Workgroup. The distribution of this translocation was analysed in the ploidy categories as defined by the flow cytometric DNA analysis(More)
