Cytogenetic studies were performed in 12 papillary serous adenocarcinomas of the ovary. Of the more than 19 clonal structural chromosome abnormalities observed in these cancers, 6q- and 14q+ were found to be the most frequent. Both markers coexisted in the cells of eight cases; in the other four cases, either a 6q- or 14q+ was present. In at least six cases, the additional segment on the long a...

Translocation t(4;11)(q21;q23) leading to formation of MLL-AF4 fusion gene is found in about 10% of newly diagnosed B-cell acute lymphoblastic leukemia (ALL) in adult patients. Patients expressing this chromosomal aberration present typical biological, immunophenotypic, and clinical features. This form of leukemia is universally recognized as high-risk leukemia and treatment intensification wit...

: Pseudolymphomatous infiltrates in Borrelia infection of the skin most commonly manifest with dense B-cell infiltrates and plasma cells. Cutaneous infiltrates of B-cell chronic lymphocytic leukemia (B-CLL) may accumulate at sites of infection, including Borrelia infection. We report an unusual constellation in a patient with synchronously diagnosed B-CLL and Borrelia infection of skin presenti...

Temozolomide (TMZ), an alkylating agent, is widely used for treating high-grade gliomas. TMZ has been reported to cause secondary myelodysplastic syndrome and acute myeloid leukemia. However, TMZ-related acute lymphoblastic leukemia is rare. Here we describe a 54-year-old woman with glioblastoma multiforme, who developed precursor-B acute lymphoblastic leukemia with translocation (4;11)(q21;q23...
