To assess the effectiveness and safety of a 24-week application of tretinoin 0.025% cream, with an alternate-day regimen, in achieving control of VLS signs and symptoms. 17 patients affected with VLS were included. The main efficacy parameters were the response rate, as defined by protocol parameters, the rate of patients achieving an improvement from baseline of ≥75% in the subjective and objective scores, and the mean reduction in subjective and objective scores throughout the treatment. The safety of the treatment was also assessed. By the end of the 24-week treatment, 12 patients (70.6%) experienced a response; 35.3% and 17.6% of patients achieved an improvement of at least 75% in subjective and objective scores, respectively. Mean scores of itching, leukoderma (pallor) and hyperkeratosis decreased significantly in the study patients, and none presented itching-related excoriations. Erythema increased compared with baseline. Six patients (35.29%) experienced some side effects related to tretinoin, mainly mild erythema and burning. None of the subjects discontinued the treatment because of side effects. Tretinoin 0.025% cream applied for 24 weeks may represent a useful alternative option to corticosteroids in the treatment of active VLS, acting particularly on hyperkeratosis and pallor.

Abstract
To assess the effectiveness and safety of a 24-week application of tretinoin 0.025% cream, with an alternate-day regimen, in achieving control of VLS signs and symptoms. 17 patients affected with VLS were included. The main efficacy parameters were the response rate, as defined by protocol parameters, the rate of patients achieving an improvement from baseline of ≥75% in the subjective and objective scores, and the mean reduction in subjective and objective scores throughout the treatment. The safety of the treatment was also assessed. By the end of the 24-week treatment, 12 patients (70.6%) experienced a response; 35.3% and 17.6% of patients achieved an improvement of at least 75% in subjective and objective scores, respectively. Mean scores of itching, leukoderma (pallor) and hyperkeratosis decreased significantly in the study patients, and none presented itching-related excoriations. Erythema increased compared with baseline. Six patients (35.29%) experienced some side effects related to tretinoin, mainly mild erythema and burning. None of the subjects discontinued the treatment because of side effects. Tretinoin 0.025% cream applied for 24 weeks may represent a useful alternative option to corticosteroids in the treatment of active VLS, acting particularly on hyperkeratosis and pallor.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
