title: Ataxia telangiectasia and acute lymphoblastic leukemia: report of a case.
abstract: We report a new case of ataxia-telangiectasia (AT) and acute lymphoblastic leukemia (ALL) and review all 21 known cases of AT and ALL. Leukemia in these patients is associated with a male predominance, age older than 10 years at diagnosis, a white blood cell count higher than 50,000 mm3, and a fatal course. Four patients have been reported who developed T-cell leukemia, 3 null-cell leukemia and 1 B-cell leukemia. The AT-ALL patients appear to be at risk for infections related to their immunodeficient status and ALL chemotherapy. In addition, neurologic deterioration has been noted during the early phase of therapy.
