title: [The clinical significance of extratesticular originating tumors (author's transl)].
abstract: A case of large retroperitoneal metastasis of a seminoma is demonstrated. The primary tumor was impossible to recognize clinically. The extremely scarred primary tumor was at last discovered histologically in the normal appearing testis on the same side. This experience leads to the conclusion that the diagnosis "extratesticular originating testicular tumor" not be accepted unless a "burned-out" tumor can be exluded histologically in the ipsilateral testis.
