Cutaneous leishmanasis (CL) may present with unusual clinical variants such as acute paronychial, annular, palmoplantar, zosteriform, erysipeloid, and sporotrichoid. The zosteriform variant has rarely been reported. Unusual lesions may be morphologically attributed to an altered host response or owing to an atypical strain of parasites in these lesions. We report a patient with CL in a multidermatomal pattern on the back and buttock of a man in Khozestan province in the south of Iran. To our knowledge, this is the first reported case of multidermatomal zosteriform CL. It was resistant to conventional treatment but responded well to a combination of meglumine antimoniate, allopurinol, and cryotherapy.

The insignificant cosmetic effect of minoxidil solution caused discontinuity of treatment among almost all patients.

Statistically, sulfasalazine was more effective than placebo in reducing cutaneous lesions and improving pruritus after 6 weeks of treatment. According to our study, sulfasalazine is a relatively safe and effective treatment option and may be an alternative therapy for the treatment of generalized lichen planus.

Objective: Melasma is an acquired hyperpigmentation disorder, and reactive oxygen species play important role in regulating melanin synthesis. Lycopene is one of the most effective oxygen neutralizers among tomato-derived carotenoids. Also, hydroquinone is a compound that has been used for the treatment of hyperpigmentation by mechanism of tyrosinase inhibition and can be found in wheat.Methods: An appropriate cream formulation containing 0.05% tomato lycopene and 3.45% wheat bran extract was prepared, and physicochemical characterization was performed. The prepared formulations were applied twice a day for three months in combination with SPF = 30 sunscreen by 22 patients diagnosed with melasma. MASI score in two groups was evaluated at weeks 0, 3, 6, 9, and 12 and 1 month after the treatment. Results:The prepared formulation shows smooth and homogeneous appearance with suitable spreadability and viscosity. The MASI score of intervention group from the sixth week until the end of the treatment was significantly decreased compared to the onset of the treatment (P < .05), and the mean difference of the MASI score and the rate of skin discoloration in intervention group (0.53 ± 0.47 and 3.73 ± 1.90, respectively) were significantly higher than in placebo group (0.14 ± 0.20 and 0.91 ± 0.07, respectively; P < .05). Size of melasma during the study was decreased significantly from 6.59 ± 3.47 to 5.97 ± 3.83 (P < .05). Conclusion:The data of mean difference of the MASI score indicated skin improvement in intervention group. Meanwhile, no recurrence was observed one month after the end of the treatment. These data suggest that the prepared formulation containing lycopene and wheat bran extract is safe and could be promising as an efficacious cosmetic treatment.

Introduction: Generally affecting women, melasma is the acquired disorder of hyperpigmentation, and researches are still ongoing to find an effective, fast, and low-side-effect drug treating this disease. The present study is aimed at comparing the efficacy of topical metformin and placebo in the treatment of melasma. Methods: Sixty patients with melasma were treated in placebo and topical metformin recipient groups in a double-blind clinical trial. In addition to the demographic and laboratory findings of patients before and after the intervention, the MASI Score of patients in weeks 0, 4, 8, and 12 of the study and then one month after the study were analyzed using SPSS version 20 software. Results: The mean age of the studied patients was 35.25 ± 7.11 years. No significant difference was observed between the phenotypes (P= .49) and the type of melasma (P= .63) in the two groups. The mean MASI score of patients at the time of being included in the study in the placebo group was 10.47 ± 3.08; and in the metformin group, it was 11.93 ± 4.64 (P = .16). Compared to the beginning of the study, the MASI scores were significantly decreased in both groups of placebo (P = .00) and metformin (P = .00) one month after the end of the study; nevertheless, no statistically significant difference was observed between the MASI Scores of two groups in any of the study periods (P > .05). Conclusion: The results of the present study showed that metformin cream significantly declines the patients’ MASI score and does not have any effect on patients’ laboratory markers. Of course, no significant difference was observed between the MASI scores of the patients receiving metformin and the placebo group; however, the MASI score decrease trend continued until the 12th week; while in the placebo group, no significant decrease was seen after eight weeks.
