I just had a lichenoid keratosis removed by a plastic surgeon. My dematologist said it looked like a squamous cell carcinoma, which I have had on the same leg. For that reason alone, I had it removed. It came back as benign, however, I have been reading that a lichenoid keratosis is like a pre-cancerous actinic keratosis, which can turn into cancer. I am happy it is gone.
