title: Adult teratoma of the testis metastasizing as adult teratoma: case report and review of literature.
abstract: A case of adult teratoma of the testis in a 19-year-old white man is presented, The tumor metastasized to the retroperitoneal lymph nodes and the metastases were also well differentiated, benign-appearing tissues. This case suggests that even the benign-appearing components of these tumors have malignant potential. Because these tumors are malignant, they should be treated by radical orchiectomy and radical retroperitoneal dissection.
