Question: What Circular Rashes Scar?

 CelticLabyrinth - Wed Jan 24, 2007 1:36 pm


I was curious if any circular rashes besides discoid rashes scar with tan spots? Would any circular, scaley, upraised, red rash with well defined borders that eventually scars be considered a discoid rash? And is it possible to have just one of these rashes?

User avatar The term discoid generally refers to a circular or oval lesion. Thus, any rash that has this shape can be termed discoid.

Also, any rash that is inflammatory in nature (be it an infection, eczema, psoriasis, etc.) can cause post-inflammatory hyperpigmentation. This may be what you are seeing when you see the tanned areas that remain.

Your description of the rash makes me think you may be referring to psoriasis or possibly numular eczema.

Best wishes.
