title: Detection of HTLV-I (human T-cell lymphotropic virus, type I) proviral DNA in leukemic cells from a French patient with Sezary syndrome.
abstract: Human T-lymphotropic type I (HTLV-I) proviral sequences were detected in leukemic cells of a patient living in Marseilles (south of France) and suffering from Sezary syndrome. He did not have any travel history outside France and did not receive blood transfusion or hepatitis B vaccination. This case of HTLV-I positive Sezary syndrome is the first one described outside the known endemic regions for HTLV-I. Moreover, this patient was found to be negative for viral antibodies. This observation should therefore stimulate new and thorough analysis of the association of this human retrovirus with leukemia and lymphoma in the Mediterranean region, both by seroepidemiological and molecular biology techniques.
