RESUMEN
Primary testicular non-Hodgkin lymphoma [NHL] is an uncommon extra nodal presentation, accounting for 1% of all NHL and 1 to 9% of testicular neoplasms. Median age at time of presentation is 60 years old. Anthracycline based chemotherapies are most frequently used. To analyze baseline characteristics, treatment modalities and survival of six cases of primary testicular non-Hodgkin lymphoma. We screened 46 testicular neoplasm cases registered from January 1999 to January 2009 and found six primary testicular lymphoma patients. These six cases were analyzed for baseline clinical features, investigations, treatment and outcome variables. Median age was 50 years old and median duration of symptoms was 4 months. All patients had testicular swelling. Four patients had abdominal lymphadenopathy. Most patients had diffuse large B-cell histology. All patients underwent high inguinal orchidectomy and five were treated with anthracycline based chemotherapy. Four patients completed therapy and one of them relapsed two years later. Primary testicular NHL is an uncommon entity and with current combined modality treatment, the outcome may be as good as nodal NHL
