re-curring round skin rash with raised edges
I have a round rash that looks like a bruise on my upper-arm
that is almost perfectly round and has raised edges and sort of
flat and pale in the middle that has been getting larger in the
three weeks I have had it, it started out small.  no itching at
all.  I had this similar about a year ago and I saw a
doctor who did biopsy and antibody blood test and the tests
came back negative.  They gave me a cream to put on the last two
times this happened and eventually went away but took about three
weeks.  Do you have any idea what this might be?  I am
just concerned because it went from about a size of a dime to now
about 1 inch and a little in diameter.

Thanks for your help

I'm afraid I don't know what it is.  I suggest you contact the doctor who did the biopsy and ask whether the recurrence might she any new light.  I will say that recurrent conditions are not generally progressively worse.  They can vary a bit in location and sise without the changes necessarily implaying anything much.  Next time it may well go back to the size it was before.

Sorry I can't be more specific.
