United Kingdom

I have a James Grieve Apple Tree and when recently removing a greaseband I found that underneath it was some kind of reaction to the band. The trunk was only affected under the band and that area seemed to have raised blotches with like an orange-browwn surface. I have looked all over the internet but can find nothing like it. Has anyone any ideas of what it is and how to treat it?
