Overview

Scrotal masses must be differentiated from other diseases that cause scrotal swelling,scrotal pain,such as testicular tortion ,epididimitis,testicular tumors,inguinal herniation and many other diseases.

Differentiating Scrotal masses from the other Diseases

Scrotal masses must be differentiated from other diseases that cause scrotal swelling,scrotal pain,such as testicular tortion ,epididimitis,testicular tumors,inguinal herniation and many other diseases.
