Background: The skin is one of the most affected organs in tuberous sclerosis complex and angiofibromas are seen in almost 80% of such patients. These benign tumors impose a great psycho-social burden on patients. Objective: The aim of the study was to evaluate the effectiveness and tolerability of topical sirolimus for facial angiofibromas in patients with tuberous sclerosis complex. Methods: This was a prospective, single-blinded, cross-over study which involved twelve patients. We investigated the effect and safety of topical 0.1% sirolimus, which was obtained by crushing sirolimus tablets and mixing it with petrolatum. The patients were asked to apply the cream to one side of their face, and vaseline to the other side. The effect of topical sirolimus was evaluated using the “facial angiofibroma severity index.” Results: There was a significant improvement in the redness and extension of the tumors on the sides to which the active ingredient was applied. Some side effects such as itching and irritation occurred in three patients, which were treated with topical hydrocortisone cream. Conclusion: Topical sirolimus appears to be a promising, fairly well tolerated treatment for facial angiofibromas in patients with tuberous sclerosis complex. Although its efficacy diminishes with time, repetitive usage is effective.
