Results of PCR for HTLV-1. In smouldering ATLL (case no. 51), strongly positive bands were detected with all four sets of primers (lanes 1 through 4). In CTCLs in HTLV-1 carrier (case nos. 52 and 53), weakly positive bands were detected with all four sets of primers (lanes 5 through 8). In 50 CTCLs, no bands were detected for HTLV-1 (lanes 9 through 12). M: molecular marker; lanes 1 and 5; gag (198 base pairs [bp]), lanes 2 and 6; pol (120 bp), lanes 3 and 7; env (209 bp), lanes 4 and 8; pX (327 bp).
