Update. I had an appointment with my dermatologist. Unfortunately the appointment was only for annual full body visual scan for moles. She was not prepared to discuss the lichen. When I disrobed you could see on her face her surprise at the extent of my discoloration. She let me know she’d be researching, talking to my rheumatologist, and perhaps my GYN and get back to me. Another term she introduced is morphea (localized scleroderma). I Googled and found images that resemble the look of my torso. Stay tuned. Oh, I asked about photo therapy and she says she knows of no equipment in this town . . . but was not resistant to researching further.
