Eczematous drug eruption (Q91670)

Drug eruptions are rarely eczematous in nature and a diagnosis of eczematous drug eruption should be made only when there is convincing evidence that the eczema is related to drug exposure. They may occur as a result of prior topical sensitization to an allergen contained in or which cross reacts with a compound present in a medication administered systemically (systemic allergic contact dermatitis).
