Abstract

Sixty cerebrospinal fluid (CSF) samples were obtained from 28 children with terminal deoxynucleotidyl transferase (TdT) positive acute lymphocytic leukemia (ALL). Cell morphology was evaluated using Wright's stained cytocentrifugation prepared slides. The presence of nuclear TdT was detected by an immunofluorescent (IF) assay. Evaluation of CSF mononuclear cells using these two methods simultaneously allowed us to differentiate between leukemic and nonleukemic pleocytosis. Agreement between cytomorphology and TdT in identifying CNS lymphoblasts was found in 55 of 60 samples. Seventy-two per cent of the TdT-positive samples were obtained from children with CSF cell counts less than 10 WBC/mm3. We recommend that these two methods be used in conjunction when evaluating CSF mononuclear cells from children with TdT positive ALL.
