I have a brown mark on my left thigh for the past 2 years. It has grown maybe 5-10% since I first saw it. I've already consulted with different dermatologist(s) 3 times over the past 2 years (last one being 2 months back) and they've told me not to worry. I was asked to use flutivate cream but later asked to discontinue after diagnosing the mark as benign. I may be paranoid here but it worries me that another small spot has appeared next to the original mark just today it seems. Attaching image for reference.
