How to treat it? I had a vascular lesion on the tip of my nose, roughly about 4mm by 4mm . Circular and brownish black in colour. I went to the dermatologist and they told me it is better to get it removed, so i underwent something known as radiosurgery. The machine they used was knows as ellman something. However its been 2 weeks now, and the scab has fallen off twice and i picked it off by mistake while washing my face . The removal has left some sort of a dent on my nose. will it heal and merge with surrounding skin?
