BACKGROUND: Adult T-cell leukemia/lymphoma (ATLL) is a neoplasm of the mature helper T-lymphocyte. Human T-lymphotropic virus type 1 (HTLV-1) has been shown to be the cause of this neoplasm. Recently, however, the HTLV-1 genome has been found in some patients with cutaneous T-cell lymphoma (CTCL), which suggests a causal relation of HTLV-1 to CTCL. Thus, the relation between the HTLV-1 genome and CTCL, as well as the difference between ATLL and CTCL, have come into question.
METHODS: The authors examined two patients with CTCL whose serum anti-HTLV-1 antibodies were constantly positive. The Southern blot technique, inverse polymerase chain reaction (IPCR), and polymerase chain reaction (PCR) with four sets of primers for gag, pol, env, and pX regions of HTLV-1 were used to clarify the distinctions between ATLL and CTCL.
RESULTS: Clinically, one patient presented with multiple subcutaneous nodules with involvements of the internal organ, and the other patient was typical for mycosis fungoides. No integration of HTLV-1 DNA was detected by IPCR or the Southern blot technique in either patient. PCRs with the four sets of primers were all found to be positive for HTLV-1 except one.
CONCLUSIONS: The authors conclude that ATLL should be differentiated from CTCL in view of the responsibility of HTLV-1 for promoting or maintaining CTCL.
