Kenalog Granules After Injecting Into Encapsulated Cyst?

I had an ecapsulated acne cyst for 6 months and have had it injected with kenalog countless times. It now looks white almost like scar tissue in the middle. A surgeon I saw said it could be cortisone granules; Is this very likely? Or is it more likely scar tissue?. It doesn't hurt. It just started looking white during the last 3-4 weeks. The cyst is very walled off and I have scarring around it so maybe the cortisone isn't dissapating like normal? If so is there a way to get rid of the kenalog?
