Patients with lupus erythematosus (LE) often have skin signs and develop many different types of lesions. LE skin diseases are divided into two broad categories: those skin lesions that occur only in people with LE, known as LE-specific skin lesions, and those skin lesions that can occur in people with LE, but can also occur in other diseases (LE-non-specific skin lesions). There are three broad categories of LE-specific skin lesions: chronic cutaneous LE (CCLE), or diseases limited to the skin, subacute cutaneous LE (SCLE), and acute cutaneous LE (ACLE). The most common lesion in CCLE is known as discoid LE; however, discoid skin lesions may appear in a patient with any type of LE.
