### Patient: Doctor, I have a skin growth and mass in my scrotum. Also, I am experiencing groin pain and have a lump or mass on my leg. What is wrong with me? 
### Doctor: Based on your symptoms, it sounds like you may have a spermatocele, which is a cyst that forms in the epididymis, a small tube located behind your testicles. It can cause pain and swelling in the groin, as well as a mass or lump within the scrotum.
