Abstract:
BACKGROUND: Recent reports suggest that Epstein-Barr virus (EBV) may play an important role in such a wide spectrum of human neoplasia. Recently, peripheral T cell lymphomas and particularly, angiocentric lymphomas (ACL), increasingly are reported to be associated with EBV.Nasal-type and nasal T/NK cell lymphoma (TNKL) have recently been reported to comprise most of ACLs. The prognosis of these tumors has been extremely poor. OBJECTIVE: The purpose of this study was to investigate EBV association in primary or secondary cutaneous T-cell lymphoproliferative disorders and to identify any prognostic association. METHODS: Thirty six patients with primary or secondary cutaneous T-cell lymphoproliferative (CTCL) disorders were examined to evaluate the presence of Epstein-Barr virus using in situ hybridization for EBV-encoded RNA (EBER). RESULTS: EBER was detected in tumor cells in one third of the total cases (13/36); 4/4 secondary skin lymphoma from nasal TNKL, 8/8 primary cutaneous nasal type TNKLs and 1/5 mycosis fungoides (MF).EBER was not detected in the following disease: 6 cases of anaplastic large cell lymphomas (ALCL) including 2 cases of probable NK-like T cell lineage, 3 lymphomatoid papulosis, 2 CD56 (-) T cell ACLs and 7 subcutaneous panniculitic T-cell lymphomas (SPTL) by Revised European-American Lymphoma (REAL) classification and recent concept of further classification into NK-cell lineage. One case of T-cell pseudolymphoma as a negative control was also negative in EBER. CONCLUSION: High incidence of EBV was observed in primary or secondary CTCLs in Koreans, with predilection for nasal and nasal type TNKL. In MFs, an erythrodermic MF with fatal outcome was associated with EBV and the EBV detection might reflect worse prognosis in MFs as seen in an aggressive course of nasal and nasal type TNKLs.
