Probably you're fine: Here's lot's of info on that Dx. http://www.expertconsultbook.com/expertconsult/ob/book.do?method=display&decorator=none&eid=4-u1.0-B978-1-4377-0859-2..00016-4--bb0015 If you doubt the professor - get a 2nd opinion, but I expect they'll also agree if they look at it. Again, if they agree to do a biopsy and you want one.....

If it goes into: proximal cuticle or matrix then yes, if it changes at all then yes, if you have family history of melanoma than yes. If you are worried then yes. But it certainly may be a benign melanonychia
