Diffuse large B-cell lymphoma presenting with hypercalcemia and multiple osteolysis.

Osteolysis and hypercalcemia are observed in 5-15%, and 10%, respectively, of malignant lymphoma patients during their clinical course. However, both osteolysis and hypercalcemia are uncommon at onset of the disease. We encountered a 24-year-old male non-Hodgkin's lymphoma patient who had multiple osteolytic lesion from the onset of the disease and repeated episodes of hypercalcemia during the clinical course.

Aberrant methylation in promoter-associated CpG islands of multiple genes in therapy-related leukemia.

Methylation profile was analyzed in eleven cases of therapy-related leukemia (t-leukemia) for p14, p15, p16, Rb, hMLH1, hMSH2, MGMT, APC, RAR beta, DAPK, RIZ1, FHIT, and SOCS-1 genes by using methylation specific polymerase chain reaction (MSP) analysis. Six (55%) of eleven cases showed methylation of at least one gene. The average time to the development of t-leukemia after the treatment of the primary tumor was significantly shorter in patients with methylation than those without methylation (49.

Peripheral T-cell lymphoma presenting with rapidly progressing myelofibrosis.

Myelofibrosis following peripheral T-cell lymphoma has rarely been reported. Described here is a case of peripheral T-cell lymphoma with myelofibrosis and elevated transforming growth factor beta (TGF-beta). A 69 years old male was admitted due to anemia and thrombocytopenia.

EBV associated hemophagocytic syndrome accompanied by central pontine myelinolysis.

The development of central pontine myelinolysis (CPM) has rarely been reported in association with hemophagocytic syndromes (HPS). Here we report a unique case of Epstein-Barr Virus (EBV)-related HPS which was accompanied with CPM. A 72-year-old man who had no significant medical history was admitted to our hospital due to high fever and progressing dysphasia and dysarthria.
