How timely this post is for me. In late April this year I noticed a "place" on my left forearm that caught my attention. I have lichen planus so I thought that's what it was. It aggressively became larger and more noticeable. When it was about 2 weeks in developing I was able to get to my dermatologist the same day. Good fortune, I thought. He looked at it and said "cancer does not develop that quickly. Let's give it a month to see what it does." After only two weeks I came back to let him know that this is something that does need attention. I had already had four squamous cancers--one place had to have plastic surgery. This visit convinced him to do a biopsy. It came back squamous. I had open wound surgery rather than Mohs because the doctor said insurance would not pay for Mohs because of where it was located. I even asked how much it would be to pay out of pocket because I just wanted the best type of surgery. I let him convenience me that the open wound surgery would be a good way to go. I did daily wound cleaning and bandage changes for 2 1/2 months. Follow up visits revealed the wound was healing well, "looks great." After the last wound check a nodule came up rather suddenly and the perimeters of the wound became harder and light colored. I went back to the derm and the nurse practitioner said she did not like the look of it and the cancer may be returning. She said lets give it two weeks and watch it. After two weeks it was worse. She took a picture and said she would check with the doc to see if it should be biopsied. I told her I wanted the doc to come look himself and he did. It was decided to biopsy and ask for STAT pathology as he agreed it appears to be cancer again. Now we wait for pathology with averages 12 days for a report and then appt with a Mohs surgeon. The first surgeon is the only one who said that lichen planus can turn into cancer "only if active LP." I hope this experience is helpful to others.
