Dermatitis

Rashes with lupus come in all different shapes, sizes and places. This article has some more information on the different types of rashes: https://lupus.net/symptoms/rash. Its possible that the rash on your finger is related. Have you been able to show this to your doctor?

It may be like a lupus lesion from discoid lupus. Sometimes with the butterfly rash I get other lesions over my body. Does the fingertip hurt at all around the rash? The best thing is to send your doctor that picture to be sure. He/she would be better able to assess it and give you a more definitive answer. I hope it feels better and clears up soon. ~Racquel~ lupus.net team member

Jodi Lynne, I started getting a rash on fingertips and around my finger nails on my right hand about 8 months ago....comes and goes....very sore/sensitive to touch, red and enflamed. By the time I can get in to my Rheumatologist takes a few weeks, and it is starting to dry up.....he just says that it looks like Lupus Rash, but seems to be healing on its own, and does nothing. Then a few weeks after healing it comes back.....I've sent messages and pics to Rheumatologist when reoccurs, but thus he doesn't seem concerned. However my Primary Physician gave me a steroid cream to use on it which helps with the pain, itch, and inflammation of it. I may be looking for a new Rheumatologist.

I don't get dermatitis on my fingertips, but I have recently begun developing dermatitis on the corners of my mouth. I've been using a steroid cream on it, which is somewhat helpful when I'm using it, but the dermatitis has been reappearing once I stop using the steroid cream. I also sometimes use CeraVie healing ointment, which was recommended by my dermatologist. Good luck with everything!
