A case of chronic actinic dermatitis treated with topical tacrolimus.

Abstract

INTRODUCTION:

The treatment of chronic actinic dermatitis (CAD), a sun-induced disorder characterized by a persistent eczematous eruption, involves photoprotective measures, topical corticosteroid therapy and, in more severe cases, systemic immunosuppression. The potential side effects of systemic immunosuppressant drugs prompted us to evaluate the efficacy of topical tacrolimus for treatment of CAD. PATIENT AND TREATMENT: A 58-year-old man with CAD, resistant to previous treatment with topical and systemic corticosteroids, oral cyclosporine and PUVA-photochemotherapy, was treated with tacrolimus ointment 0.1% once a day.

RESULTS:

Tacrolimus ointment led to significant improvement of pruritus and severe eczematous skin lesions after 20 days of treatment.

CONCLUSIONS:

Tacrolimus shows a beneficial effect on CAD; this could be attributed to the fact that CAD is characterized by a lymphohistiocytic infiltrate producing a chronic eczema and that tacrolimus blocks the activation of lymphocytes and other immune system cells, also inhibiting the release of mediators from cutaneous mast cells and basophils.
