A case of primary myelofibrosis involving lymph node and with a novel cytogenetic abnormality [del (18) (p11.2-3)] is reported. The abnormalities are identical among specimens from the lymph node, peripheral blood, and bone marrow that were analyzed years apart. Additionally, we show that the infiltrate by dysplastic megakaryocytes in the lymph node morphologically mimics a metastatic mesenchym...
Preoperative peripheral blood reverse transcription-PCR (RT-PCR) for prostate-specific antigen (PSA) [RT-PCR-PSA] is not associated with an increased risk of progression after radical prostatectomy. We tested the hypothesis that early postoperative peripheral blood RT-PCR-PSA would detect prostate cancer cells persisting in the circulation that would be associated with disease progression. The ...
We experienced a 58-year-old Korean man with adult T-cell leukemia/lymphoma with features of histologically anaplastic large cell lymphoma involving the skin and testis. The patient had cutaneous nodules in both extremities and a palpable right testicular mass. Right orchiectomy was performed and specimens of removed testicle and skin nodules showed immunohistologically anaplastic large cell ly...
AIM To investigate whether human herpesvirus 6 (HHV-6) can cause latent infection of liver tissue. METHODS Peripheral blood and liver tissue were collected from 25 living related liver transplant recipients at the time of transplantation. An avidin-biotin complex peroxidase method was used to identify HHV-6 antigen in the liver tissue. A nested polymerase chain reaction (PCR) was used to dete...
INTRODUCTION Enoxaparin prophylaxis prevents venous thromboembolism in surgical patients. Real time anti-Factor Xa monitoring for surgical patients on enoxaparin prophylaxis is increasingly common. PRESENTATION OF CASES We report on three cancer patients with therapeutic or supratherapeutic anti-Factor Xa levels while on prophylactic doses of enoxaparin after surgical procedures. In all cases...
Using X-linked clonal analysis, mechanism of action of alltrans retinoic acid (ATRA) was sought in a 16-year-old female with relapsed clonally evolved acute promyelocytic leukemia (APL), who achieved complete remission. On ATRA, metamorphosis of peripheral blood leukemic promyelocytes to mature neutrophils was observed, despite the persistence of t(15;17) in 100% of bone marrow metaphases. DNA ...
PURPOSE Using concurrent tumor samples from different anatomical sites, we compared expression of the therapeutic targets CD25 and CD30 in T-cell lymphoma (TCL). EXPERIMENTAL DESIGN We examined levels of CD25 and CD30 by flow cytometry in tumor cells from peripheral blood and lymph node in 13 cutaneous TCL patients and by immunohistochemistry in concurrent lymph node and skin biopsy specimens...
BACKGROUND Human enteroviruses (EVs) may have a role as a possible risk factor in the pathogenesis of MI. The aim of this study was to evaluate the presence of enterovirus genomic RNA in peripheral blood samples of patients with acute myocardial infarction (MI). METHODS We investigated the presence of enterovirus genomic RNA in the peripheral blood of 115 patients with acute MI hospitalized i...
We examined lymphocyte subpopulations in the peripheral blood and serum concentrations of immunoglobulin (Ig) in 8 patients with tsutsugamushi disease. In 7 of the 8 cases, there was a 4-fold or greater increase in IgG and IgM antibody titers between the initial and convalescent serum specimens. In one case, there was no increase, but IgM antibodies were detected with diagnostically significant...
