An adenomatoid tumor is the most common paratesticular benign tumor that accounts for approximately 30% of all paratesticular benign neoplasia. According to literature, most adenomatoid tumors are located in epididymis, but have also been found in seminal ducts, prostate and tunica albuginea. Etiology is still unknown. Important methods in diagnosing an extratesticular form of adenomatoid tumor include anamnestic data and physical examination, as well as ultrasound imaging. Reported data recommends rapid perioperative biopsy in case of unspecified scrotal pathologies, which in turn reduces the need for radical orchiectomy and preserves ednogenous testosterone production as well as spermatogenesis.
