Papillary Cystadenoma of the Epididymis

Abstract
There have been 33 previously reported cases of papillary cystadenoma of the epididymis. To our knowledge we report the first case of this benign neoplasm in Scandinavia. The cystic tumor occurred unilaterally in a 44-year-old man who had no signs of von Hippel-Lindau's syndrome or infertility. Papillary cystadenoma of the epididymis must be distinguished from neoplasms of the testis, particularly teratoma.
