Han, Oh, and Seo: Testicular T-cell Lymphoma

Abstract

Testicular lymphomas are rare, accounting for only 5% of all testicular tumors. The majority of these tumors are part of the disseminated disease process, and only rarely arise as a primary lesion. Most testicular lymphomas are B-cell lymphomas. Testicular T-cell lymphomas, are rarely detected, but have many subtypes according to the immunohistological feature, and have poor outcome and high relapse rates, even with a localized disease. Herein, 2 cases of testicular T-cell lymphoma, initially manifesting in the testis, are reported, with a review of the clinical features and outcomes.
