Primary diffuse large B-cell lymphoma of the testis.

Non-Hodgkin's lymphomas are chronic lymphoproliferative disorders, with nodal or extranodal onset, most of which being digestive tract lymphomas. Testicular primitive lymphoma generally affects men; it is rare but aggressive type of lymphoma. We present the case of the only patient diagnosed with testicular lymphoma in Hematology Clinic of Craiova, Romania, in the last 20 years. Histopathological and immunohistochemical exams confirmed the diagnosis of diffuse large B-cell lymphoma, and the stage was IIB. According to International Prognostic Index (IPI) score, the patient was classified as low risk. He received combined treatment consisting of surgery, chemotherapy, central nervous system prophylaxis and radiotherapy. The outcome was very good, the patient achieving complete remission. After 36 months, he is still in complete remission with clinical and biological evaluation performed every three month, and computerized tomography once a year.
