Letter to the Editor

Primary Epstein-Barr virus-negative nasal-type natural killer/T cell lymphoma of the testis Nasal-type natural killer (NK)/T cell lymphomas involving extranodal presentation such as in the central nervous system (CNS), skin, lung, gastrointestinal (GI) tract, and testis are an example of uncommon non-Hodgkin's lymphoma. They are represented by the following immunophenotypic profile: CD2+, surface CD3-, cytoplasmic CD3+, CD56+, and a strong association with Epstein-Barr virus (EBV) [1-3]. In particular, nasal-type NK/T cell lymphoma presenting as a testicular tumor is quite rare, even in Asia where this type of lymphoma is prevalent. We report herein a testicular EBV-negative nasal-type NK/T cell lymphoma case with a long-term survival.

A 76-year-old Japanese man was admitted due to left-sided painless testicular enlargement in May 2007. There was no his-

Nasal T/NK-cell lymphomas can be further separated into those of natural killer (NK) cell lineage or of T-cell lineage, with differences in cellular phenotype, T-cell receptor (TcR) gene rearrangement and TcR transcript expression. Both NK-and T-cell subtypes are closely associated with Epstein-Ban

A 74-year-old Japanese man presented with systemic lymphadenopathy, hepatosplenomegaly, and erythroderma in December 1991. A characteristic pattern of anti-EBV antibodies was suggestive of latent EBV infection. A skin tumor biopsied in April 1993 contained biclonal EBV genomes diffusely in the infil
