This study has been posted quite a lot on this forums as far as I can remember. Look at both pictures very closely. They are exactly the same image, but the second on is photoshopped. Of course that doesn't mean that the case in the case report isn't real.. But it seems suspicious. Also, the condition in the first pictures is not even close to why I personally would call EC. But that's just a matter of definition, I guess.
I've been using a calendula ointment for many months (in a petroleum jelly base), and it hasn't done anything to cure the condition.
