[Scrotal masses: considerations on two cases of epididymal tumors]

The scrotum is a fibromuscular sac that contains the testis, epididymis, spermatic cord and the associated fibrous coatings. All these components can be affected by different variety of pathologic phenomena, including congenital, inflammatory and neoplastic events. When a scrotal mass is observed, there are two basic questions to be answered, i.e. if the mass is intratesticular or extratesticular, and if it is of cystic or solid nature. Apart from a few rare exceptions, intratesticular solid masses should be considered malignant, while extratesticular masses with liquid content are generally benign. CASE REPORTS. Two cases of tumor are hereby presented: they originated from the epididymis, and their clinical presentations did not allow making a differential diagnosis between benign and malignant tumor during the preoperative examinations. After presenting the diagnostic doubts to patients, and once obtained their informed consent, surgeries were performed allowing for a precise histological diagnosis, and at the same time, proving to be also valid therapeutic tools.
