Interesting that only 30% have this "classic" feature of SLE.
I have not had the butterfly rash on my face, but I do have bilateral pigmentation darkening on both sides of my neck in exactly the same spot/same shape.
I did have a rash on my ankle that lasted a few days, but it didn't weep, itch or anything.
Perhaps that's part of why I'm still in denial--I haven't had any of the supposed classic signs of SLE. I know I should count my blessings, but it makes me doubt the diagnosis at times.
