Evidence for reactivation of human herpesvirus 6 in generalized lymphadenopathy in a patient with drug-induced hypersensitivity syndrome.

The present case provides direct evidence of human herpesvirus 6 reactivation in resected lymph node tissue in a patient with drug-induced hypersensitivity syndrome. This case clearly demonstrates that appropriate pathological evaluation of lymphadenopathy for drug-induced hypersensitivity syndrome, which mimics malignant lymphoma in clinical, radiological, and pathological findings, is required.

[Sustained remission of MDS overt leukemia associated with abrupt discontinuation of immunosuppression following relapse after the second course of allogeneic hematopoietic stem cell transplantation].

The case of a 32-year-old female with relapsed myelodysplastic syndrome (MDS) after second course of allogeneic transplantation is described. The peripheral blood stem cell transplantation was performed as early as 3 months after the initial bone marrow transplantation because of rejection and relapse; however, the patient again relapsed 2 months later. Immediate discontinuation of cyclosporine resulted in the progression of pancytopenia and the development of high fever, liver dysfunction and skin eruption.

Prognosis of elderly patients with acute myelogenous leukemia: analysis of 126 AML cases.

We retrospectively analyzed 126 acute myelogenous leukemia (AML) patients aged > or =60 years who had all been referred to the same hematological department between 1989 and 1999. In 76 de novo AML cases, 53 patients (median age, 72 years) were treated with combination chemotherapy (CT) for remission induction. Complete remission (CR) rate was 57.
