Aims: Testicular and extratesticular masses can be found in scrotum. Although most of those masses are intratesticular, some develop from paratesticular tissues. In this case report, we analyzed the results of a patient admitted to the hospital complaining of a scroted mass causing pain. Case Report: Epididymectomy was performed to a 5-year-old man patient with an expanding scrotal mass which was causing pain. After running some tests, performing initial investigations like scrotal ultrasound scan and MR, there were still doubts about the risk of malignancy. To be sure about the mass whether it is a tumor or an infection, epididymectomy was decided to be performed. The day after the operation, the patient was discharged with no complications. His complaints eased after the operation. Conclusion: The scrotum is the sac that contains the testicles. A scrotal mass can be originated from testicles or paratesticular tissues. Although 3% of all solid extratesticular masses are malignant, previous studies have shown that the malignancy rate can raise up to 16%. That’s why scrotal masses which are not certainly benign must not be ignored and epididymectomy should be performed.
