title: [Paratesticular adenomatoid tumor, presentation as epididymal pain].
abstract: OBJECTIVE
  To describe an additional case of adenomatoid tumor of the epididymis.
  
  
  RESULTS
  A 55-year-old man consulted for epididymal pain. Palpation and ultrasound evaluation disclosed an epididymal tumor. The patient underwent orchidectomy; histological examination of the surgical specimen confirmed an adenomatoid tumor.
  
  
  CONCLUSIONS
  Adenomatoid tumor of the epididymis is an uncommon tumor of the paratesticular tissue. Although its etiopathogenesis remains unclear, there appears to be a mesothelial involvement. Ultrasound evaluation and clinical examination are essential in making the preoperative diagnosis. It is a benign tumor and surgical excision can achieve cure. If the intraoperative frozen section is found to be benign, the tumor can be excised or enucleated without semicastration.
