Dr. Ragi in Teaneck is one of the best dermatologists in the area. My dad and my mother-in-law have been to him several times, and he's excellent. Here's a link to his site -

I have no knowledge of plastic surgeons in the area, but I can ask my wife if you don't get a recommendation. She's an RN with Hackensack Hospital, and may know of a good surgeon.
