Official Title: A Double Blind Randomized Trial, Placebo-controled of 0.0003% Calcitriol Ointment Versus 0.1% Tacrolimus Ointment in the Treatment of Pityriasis Alba
Brief Summary: Pityriasis alba (PA) is a frequent cause of consultation in tropical areas due to its chronic course, trend to relapse and aesthetic impact. Currently, no treatment is widely accepted. The objective is to assess the calcitriol and tacrolimus ointment efficacy in the treatment of PA compared with petrolatum. Twenty lesions on the face greater than 3 cm, in individuals of phototype IV-V, aged 3-18 years are going to be randomly assigned to receive petrolatum, calcitriol, and tacrolimus twice daily. No photoprotection is going to be indicated, and hygienic habits will not be modified. Patients will be evaluated at baseline and for 9 weeks, by means of Transepidermal Water Loss (TEWL), colorimetry, clinically and by photography control.
