Primary epididymal adenocarcinoma (PEA) is exceedingly rare. Only 22 cases had been published worldwide by 2008; nearly 80% of these cases were reported before 2007. In order to investigate the current clinical status of PEA, we search for relevant literatures with “epididymis and adenocarcinoma” and “epididymal and adenocarcinoma” as keywords published between January 1997 and November 2017 in PubMed. As a result, 17 cases are identified. We review these cases and summarize new and important perspectives about the clinicopathological characteristics, diagnosis, treatment, and prognosis of PEA in the present review.
