The most typical skin rashes of systemic lupus erythematosus are called butterfly rash and discoid rash. The so-called butterfly rash is a rash on both sides of the nostrils, resembling the wings of a butterfly, and the so-called discoid rash is a circular, disc-shaped rash on the facial area. At the same time, patients with systemic lupus erythematosus may also experience reticular purpura or vasculitic rashes like those of end-finger vasculitis, all of which are typical manifestations of skin rashes in patients with systemic lupus erythematosus.
