nodular fasciitis (with focal vasular involvement)

Well, today, I have nothing to teach you! Nodular fasciitis is correct.

I posted this on facebook this morning but I thought it would be well worth putting it into the spot diagnosis comment this am.

I was reading Mark Hurt's recent blog and it reminded me that when I started training a new resident/fellow in dermatopathology, I always began by saying "treat every case as if it were a biopsy of yourself of one of your loved ones". That way, you will give it the attention that it deserves. Of course the same applies to every branch of medicine. As soon as you treat a case as just another specimen, you are lost!

Yes indeed, scrutiny is the keyword.
