title: Papillary cystadenoma of epididymis: Is there a need for further investigation in unilateral cases?
abstract: BACKGROUND
  The presence of a mass in the epididymis is not a common entity. The papillary cystadenoma of epididymis is a benign tumor which may occur sporadically or as a characteristic of von Hippel-Lindau disease.
  
  
  METHODS
  We present a case of a 27-year-old man with a right scrotal mass who was treated with surgical excision. Histopathological examination revealed a clear cell epididymal papillary cystadenoma. A computed tomography scan that was performed later showed no other abnormality or any signs of von Hippel-Lindau disease.
  
  
  CONCLUSIONS
  In this report, a case of a young man suffering from this rare tumor is discussed, focusing on the need of further evaluation in order to determinate if it occurs as a feature of VHL disease or as a sporadic form.
  
  
  CONCLUSIONS
  In unilateral cases of papillary cystadenoma of epididymis such as our patient's, literature advocates that no further examinations and expensive genetic testing is required.
