Erythema Dyschromicum Perstans: Response to Topical Tacrolimus.

BACKGROUND: Erythema dyschromicum perstans, a rare dermatosis of obscure etiopathogenesis and significant cosmetic morbidity, have no satisfactory treatment.

OBSERVATIONS: Two patients with having characteristic asymptomatic and slowly progressive, slate-grey macular lesions with distinct red borders involving the face, neck, upper trunk and limbs were diagnosed clinicopathologically as erythema dyschromicum perstans. Both were treated successfully with topical tacrolimus 0.1% ointment.

CONCLUSIONS: Overall, response to several therapeutic modalities including clofazimine and dapsone therapy is said to vary from complete failure to variable or inconsistent. Topical tarolimus provides an effective and safe alternative therapeutic option in erythema dyschromicum perstans.
