2. In an adult male, hydrocele is a relatively benign condition
-Feeling of heaviness where?
1. Hydrocele develops in a young man without apparent cause:
-It should be considered cancer until proven otherwise

-Is often asymptomatic
-Feeling of heaviness in the scrotum
-Pain in the lower back
1. What is it?
2. What can it cause?

4. Usually how big?
5. Freely movable and should do what?
6. How can they be problematic?
1. Painless, sperm-containing cyst that forms on the epididymis
2. Located above and posterior to the testes
3. Attached to the epididymis
-Separate from the testes
-May be solitary or multiple
4. Usually greater than 2cm
5. Freely movable and should transilluminate
6. Rarely cause problems
If large, may become painful and require excision
1. What is it?
