Graft failure (GF) remains a major problem in cord blood transplantation (CBT). In 36 adult patients undergoing CBT at our hospital between July 2003 and December 2009, six patients developed GF (primary, n = 5; secondary, n = 1). All six patients underwent second stem cell transplantation (SCT). Three patients had acute myeloid leukemia, one had acute(More)
Although pathological diagnosis is essential for managing malignant lymphoma, intraabdominal lesions are generally difficult to approach due to the invasiveness of abdominal surgery. Here, we report the use of percutaneous image-guided coaxial core-needle biopsy (CNB) to obtain intraabdominal specimens for diagnosing intraabdominal lymphomas, which(More)
Immunoglobulin (Ig) G4-related sclerosing disease is a recently described syndrome characterized by lymphoplasmacytic infiltration of exocrine glands or extranodal tissues and elevated serum IgG4. We report three cases of lymphadenopathy secondary to IgG4-related sclerosing disease. Histologic features of involved lymph nodes included interfollicular(More)
A 67-year-old woman presented with a right inguinal mass in May 2006. CT scan showed lymph node involvement from the right inguinal to the common iliac and (18)F-FDG-PET revealed uptake in those areas. Biopsy results indicated Langerhans cell sarcoma (LCS). Interestingly, tumor cells expressed a high MIB1 index of 30%. We administered doxorubicin,(More)
Therapy-related myelodysplastic syndrome and acute myelogenous leukemia are increasingly being recognized as treatment complications in patients receiving chemotherapy or radiotherapy for previous neoplasms. However, therapy-related chronic myelogenous leukemia is relatively rare. A 61-year-old woman with a history of radiation therapy for breast cancer had(More)
The activated partial thromboplastin time (APTT) assay is a basic hemostatic assay based on the time it takes for clots to form in plasma samples after the addition of calcium chloride. It is used to screen for various coagulation disorders. Several previous reports have suggested that magnesium (Mg) might contribute to coagulation reactions by binding to(More)
A 32-year-old woman with acute myeloid leukemia failed to achieve remission with two courses of induction chemotherapy, and she received cord blood transplantation (CBT) in a non-remission state, using an HLA-matched cord blood (CB) graft after a conditioning regimen of fludarabine (Flu) at 125 mg/m² + melphalan at 140 mg/m² + total body irradiation (TBI)(More)
Human herpesvirus-6 (HHV-6) is known to cause critical encephalitis, as a central nervous system infection, in some hematopoietic stem cell transplantation (HSCT) recipients. Chromosomally integrated human herpesvirus-6 (CIHHV-6) persistently shows HHV-6 DNA in blood, but this does not necessarily suggest active infection. The true clinical significance in(More)
A 79-year-old woman was admitted with a 5-kg weight loss and anorexia. Computed tomography showed diffuse lymphadenopathy, and thickening of the duodenal and ileal walls. The patient then underwent biopsy of these sites. Pathological examination revealed duodenal Epstein-Barr virus (EBV)-positive peripheral T cell lymphoma-not otherwise specified (PTCL-NOS)(More)
