In 2009, I had a dermal fibrous hisitiocytoma removed from my right arm. It started as a brown dot, and grew in to a lump that was about half and inch, and brown-purple in color, like a bruise. It was benign, but I was told to watch my skin for anything weird going on. The tumor has only a 30% chance of recurrence. The doctor said to watch sun exposure, which I did.
Now, I've noticed a brown spot next to my ear, under the hair line, on the right side. It's about the size of a pencil eraser and dark brown. One part is kind of round-ish, and the other part looks sort of lumpy, like a paint splatter. It's a little raised and doesn't hurt.
I would like to know what it could be and if I should see a doctor?
