Hi Doctors ,
I'm an Iranian and new here.
Unfortunately, my father , he has 52-year-old , has a big problem on his nose ! I've attached 2 images about that problem.
He refer to some doctors and they give him a lot of medicine , but those medicine haven't any effective result for treating.
I want to know what is this and how can we do for treating this skin disorder ?
This disorder is so annoying for him, and if you can have any information about it help me , please.
