The incidence of non-Hodgkin's lymphoma of the testis is in the order of 1.8% in adults. Ten cases of lymphomas histologically proven after orchidectomy are reported: 5 were diffuse large cell, 4 immunoblastic and 1 diffuse small cell lymphomas. Mean age was 56 years. Five patients had stage IE or IIE and 5 stage IV disease after staging. Seven patients had received chemotherapy followed by subdiaphragmatic irradiation and 2 with localized lymphoma were treated by radiotherapy alone after orchidectomy. Four patients in remission relapsed after 6 to 24 months. Central nervous system involvement during the course of the disease was observed in 5 cases. Five patients are still alive in remission after an 18 to 80 months follow-up.
