Non-Hodgkin lymphoma arising in the paratesticular organs without testicular involvement is rare. In most previously reported cases, the classification systems that were used are now outdated and/or immunologic studies were not done. We report the clinical and pathologic features of 2 cases of non-Hodgkin lymphoma arising in the epididymis and the spermatic cord. Patient 1 was a 35-year-old man who presented with a painless scrotal mass. Patient 2 was a 61-year-old man who presented with a right inguinal mass. Orchiectomy performed in both patients revealed a mass confined to the epididymis in patient 1 and to the spermatic cord in patient 2. Histologic examination in both cases revealed diffuse large cell lymphoma, and immunohistochemical studies supported B-cell lineage. Subsequent staging studies showed no other site of disease in patient 1 and an isolated mass anterior to the right psoas muscle in patient 2. Malignant lymphoma involving testicular adnexal structures without involvement of the testis is extremely uncommon. To our knowledge, only 6 cases confined to the epididymis and 12 cases confined to the spermatic cord have been reported previously.
