title: No evidence of KSHV/HHV-8 in mycosis fungoides or associated disorders.
abstract: The recently discovered human virus known as Kaposi's sarcoma-associated herpesvirus (KSHV) or human herpesvirus-8 (HHV-8) has been associated with body-cavity-based lymphomas in AIDS patients. It is most closely related to two other herpesviruses, the Epstein-Barr virus and herpesvirus saimiri, which are known to be associated with lymphomas in humans and nonhuman primates, respectively. To determine whether KSHV/HHV-8 is involved in the pathogenesis of mycosis fungoides (MF) and related disorders, we used a genomic PCR assay followed by confirmatory Southern blot analysis with a nested oligonucleotide probe to analyze cases for the presence of this virus. The specimens studied included fresh-frozen lesional tissues obtained from 16 patients with MF, seven with lymphomatoid papulosis, seven with primary cutaneous CD30+ large cell lymphoma of T-cell lineage, and five with Hodgkin's disease. Two T-cell tumor lines were also studied: MT4 (derived from a patient with adult T-cell leukemia/lymphoma) and Jurkat (derived from a patient with T-cell acute lymphoblastic leukemia). All cases were uniformly negative for KSHV/HHV-8, whereas Kaposi's sarcoma-positive controls and human beta-globin DNA integrity controls were appropriately positive. These findings provide strong evidence against a role for KSHV/HHV-8 in the pathogenesis of MF or associated lymphoproliferative disorders.
