Abstract
Systemic contact dermatitis (SCD) describes a hypersensitivity reaction following systemic re-exposure of the inciting allergen in previously sensitized individuals. Plants, drugs, and metals are the most common causes of SCD. In individuals with obstinate dermatitis, it is imperative to deliver history-focused patch testing with subsequent avoidance and elimination of the compound.
