Five cases of @entity1358 metastatic to the @entity1062 or its adnexa are described, including 3 that represented the initial presentation and mimicked primary @entity1062 . The @entity1 ranged from 46 to 85 years of age. Three presented with self-identified testicular masses. One @entity1 was investigated because of fever of unknown origin and was found to have a left rib @entity3 . Further work-up led to the discovery of a testicular mass. The final @entity1 had a @entity5 of the spermatic cord that was examined without knowledge that he had a prior @entity703 . All the @entity5 were unilateral. They ranged from 1.8 to 5.0 cm; multiple @entity5 nodules were present in one of them but the others were discrete solitary masses. Four @entity5 were yellow/yellow-tan, and one was gray. On microscopic examination all the @entity5 were of the clear cell type. Patterns included solid sheets, acini, cysts, alveoli, and trabeculae. Two had prominent vascular invasion. Diagnoses initially entertained in these cases included @entity19464 , @entity10693 , and clear cell @entity9296 . In 3 cases a @entity703 was discovered 2 to 4 weeks after the diagnosis of @entity1358 metastatic to the @entity1062 was rendered. On follow-up two @entity1 died of @entity5 , and two were alive (5 months and 1 year) after orchiectomy. The diagnosis of @entity1358 metastatic to the @entity1062 should be considered in evaluating a @entity5 of the @entity1062 , particularly in an older male or if the appearance suggests a @entity19464 . The differences in survival between metastatic @entity1358 and @entity11597 indicate the importance of considering the former in the differential.
