A special characteristic rash that is formed by discoid lupus, which is manifested by skin red spots on the skin and peeling and can leave scars. He often appears on the face and scalp and can cause hair loss.

Hair loss may also occur because of immunosuppressive drugs, or with exacerbations of systemic lupus erythematosus, even in the absence of rash in the scalp.

Early lesions are erythematous papules or plaques slightly elevated over time, they rose, bright red, edematous, and the center becomes depressed, the color fades and becomes atrophic, and peripheral edema develops slowly red and becomes irregular with telangiectasia. We must also mention that there is follicular plugging characterized by areas of hyperkeratosis stroll in older lesions. We have seen that, typically, the lesions heal with scarring and hyperpigmentation or hypopigmentation.

If the lesions that are involving the scalp, erythematous, scaly, the hair usually grow back, but if the lesion heals with marking of hair loss is permanent.
