[Non-Hodgkin's lymphoma: unusual testicular localization: case report].

We report on a 58-year-old man, in whom a clinical suspicion of orchitis of the right testicle was treated with antibiotics. The instored antibiotics failed to improve the clinical condition of orchitis. Previous medical history revealed a gastric lymphoma for which gastrectomy was performed, followed by combination chemotherapy. Therefore testicular biopsies were performed. These biopsies confirmed the diagnosis of testicular localisation of lymphoma. A combination chemotherapy, in association with alpha-Interferon was instaured. One year after instauration of combination therapy, the patient is in complete remission. This unusual localisation of lymphoma is discussed in regard of other cases described in literature.
