What is morphoea cure?

There is none: Morphea is a thickening of the skin that is famously difficult to treat effectively. It does not mean you are going to get the more serious diseases scleroderma or perry-romberg. One of my physician-colleagues has it, doesn't mind it, and simply calls himself "linoleum man". I hope you will not take this the wrong way, as treatment efforts, even tacrolimus, have been disappointing.
