What are the long-term effects of repeated soft tissue bruising and damage?

Athletes often suffer injuries to parts of the body from repeated stress over time. What about soft tissue? What happens if a spot on your body is repeatedly bruised and subjected to damage over and over again over a period of years?

There's two ways it can go, since your question is not specifying what soft tissue you are talking about. If it's hairless skin - it will develop calluses, and become less soft and more resistant to following damages, like string players or gymnasts get really thick and hard skin. 
If it's muscle - Inflammation, which can become chronic, then pain and discomfort. 
Also in case of any damage - regeneration, more divisions, higher chance of cancer. In dentistry they sometimes change teeth shape, if there's a spot of soft tissue, constantly irritated by teeth. Even if there's no pain or discomfort, just the fact that it keeps regenerating a lot increase the chance of cancer.
