title: Ependymoma, glioblastoma, and acute leukemia in a child.
abstract: A 5-year-old boy developed an ependymoma; 3 years later, after chemotherapy and radiotherapy, he developed glioblastoma multiforme and acute myeloblastic leukemia. His maternal grandmother had died at a young age of colon cancer. Since ependymoma is not known to predispose to other cancers, the unusual sequence of malignant disease may have been due to combined therapy in a susceptible host.
