I was diagnosed and with an epidermoid cyst on my neck. The PA injected a steroid to try and shrink it. The cyst never went away and appeared to stay large weeks after. I agreed to have surgical incision since it was on my neck above my Adam's apple and affected my swallowing/appearance. When they opened it up they realized it was ruptured inside. They cleaned it out the best they could and electro-cauterized remaining tissue that wouldn't come loose. What are my chances of this cyst coming back?
