Allergic contact dermatitis to pimecrolimus

Pimecrolimus suppresses the proinflammatory cytokine production of cutaneous T and mast cells (1). It is used to treat atopic dermatitis and is the active ingredient in the topical formulation pimecrolimus 1.0% cream (Elidel, Novartis Pharma AG, Basel, Switzerland).
