Testicular tumor: Presenting sign of lymphoma

The occurrence of a testicular tumor in a man past middle age is rather unique in that, even if it be the only abnormal physical finding, it is probably the presenting sign of generalized lymphomatous disease already present or shortly to become clinically active. Isolated lymphomas of the testis, although not unheard of, are rare. The prognosis is uniformly bad; none of the patients in our series survived or was without evidence of generalized involvement for more than a year from the time of recognition of the testicular disease.
