Therapeutic effect of Topical Sirolimus on Facial Angiofibromas in Patients of Tuberous Sclerosis Complex

Introduction: Tuberous sclerosis complex (TSC) is a rare autosomal dominant disorder. Facial angiofibromas are the most common cutaneous findings of TSC. Treatment modalities such as laser, surgery, and/or cryotherapy are employed. Topical therapy with Sirolimus, an mTOR inhibitor, showed beneficial effects. Objective: To study the effects of topical sirolimus (0.1%) on Facial Angiofibromas in patients of TSC. Methodology: Four patients with facial angiofibromas were included. They applied Sirolimus preparation twice daily, for 3 months. The Facial Angiofibroma Severity Index (FASI) was recorded pre-intervention, at 3 months and after 6 months. Results: All the patients showed a reduction in the FASI score at the end of three months of therapy. In three patients, on discontinuing therapy, there was no change in the FASI score at the end of six months, i.e., FASI 3 and FASI 6 were the same. Conclusion: Topical sirolimus is an effective treatment for facial angiofibroma in patients with TSC.
