PG - 81-4 AB - A 76-year-old woman had lymphocytosis with lymphocytes having convoluted or lobulated nuclei. These abnormal lymphocytes (leukemic cells) were positive for CD4, and some expressed IL-2R (CD25) and CD3 molecules, respectively. These morphologic and phenotypic features were compatible with adult T-cell leukemia, but serum antibodies to human T-cell lymphotropic virus type I (HTLV-I) were not detected by the particle aggregation method and an enzyme-linked immunosorbent assay. The polymerase chain reaction showed that the LTR, gag, pol, and env regions of HTLV-I proviral DNA had not been incorporated into the leukemic cells. Only the pX region was detected in these leukemic cells. FAU - Takenaka, T AU - Takenaka T AD - Department of Laboratory Medicine, Wakayama Medical School, Japan.
