title: [A case of late recurrence of germ cell tumor].
abstract: A 19-year-old male was admitted to our hospital because of retroperitoneal tumor and metastases in the lung and liver. He underwent chemotherapy followed by retroperitoneal lymph node dissection and pathologic examination revealed mostly necrotic tissue with a small amount of teratomatous tissue. Two years later, a hyper echoic lesion was found in the left testis, and left high orchiectomy was performed. The resected specimen appeared to be a burned-out testicular tumor. Ten years later, CT scan detected lymph node swelling in the retroperitoneum, and excision of the tumor was performed. Pathologic examination revealed well-differentiated adenocarcinoma. Since no primary adenocarcinoma was found, this case was considered late relapse of a germ cell tumor.
