This THING appeared on my finger about a year ago, at first I did not pay attention to it, but with time it began bothering me.
I went to a skin doctor and he couldn't tell me exactly what it was.
He tried burning it with Nitrogen 4-5 times but it didn't help, since the core of this THING always survived even after the burned skin has come off.
The THING has a rough texture.
What scares me is that about a month ago, the THING started spreading, and it already grew in 50% in a month (!).
My everyday job includes meeting with people, and this THING on my hands is really bothering me, it's really non-aesthetic.
Can you help me diagnose what this is?
I can provide photos in better resolution if required.
