Is there any new treatments for tumoral calcinosis other than surgery and control of phosphate levels?

Not realy but: Some of them get too big we could surgically taken out. Good luck, thank you.

You answered it: You have answered the question - surgery, control of phosphate. This is what we might call an orphan disease. The problem is that there are only a few people with this to generate a nucleus for therapy studies. We have tried a variety of attempts to control these large calcium deposits. Unfortunately your answer is still the best approach.
