Lupus erythematosus is a collection of autoimmune diseases in which the human immune system becomes hyperactive and attacks healthy tissues. [1] Symptoms of these diseases can affect many different body systems, including joints, skin, kidneys, blood cells, heart, and lungs. The most common and most severe form is systemic lupus erythematosus.

And just like a ton of other autoimmune diseases though, it’s not completely clear why it develops, and like most diseases it’s the result of both genetics and the environment. Alright so let’s go over a specific scenario to show how this plays out.
Certain chemical agents and drugs can also be associated with the genesis of autoimmune conditions, or conditions that simulate autoimmune diseases. The most striking of these is the drug-induced lupus erythematosus. Usually, withdrawal of the offending drug cures the symptoms in a patient.
Acute cutaneous lupus erythematosus is a cutaneous condition characterized by a bilateral malar rash (also known as a "butterfly rash") and lesions that tend to be transient, and that follow sun exposure. [1] The acute form is distinct from chronic and subacute cutaneous lupus erythematosus, which may have different types of skin lesions. [2]
