Introduction: facial angiofibromas of tuberous sclerosis are the most prevalent cutaneous manifestation, affecting 80% of patients, which cause facial lesions with negative psychosocial consequences. Newly, topical rapamycin has been established as an effective and safe therapy for this skin condition.
Purpose: to analyze the available scientific evidence about the effectiveness and safety of topical sirolimus in the treatment of facial angiofibromas in tuberous sclerosis.
Methods: a literature search was conducted in PubMed and Cochrane. Effectiveness and safety were analyzed along with the main characteristics of each formulation in all included studies.
Results: thirty studies were included involving a total of 508 patients, developed in the last 20 years. Four randomized clinical trial, 17 case series and 9 single case reports were founded. Multiple topical rapamycin concentrations (0.003-1%) and formulations (gel, ointment, solution) were found in literature. Rapamycin demonstrated its effectiveness in all studies included, except for 5 patients in a 1 b study. Rapamycin was shown to be safe for the treatment of FA.
Conclusions: Topical sirolimus can be considered an effective and safety option for the treatment of facial angiofibromas in tuberous sclerosis. However, further long-term studies need to establish an evidence-based therapeutic protocol.KEY MESSAGEUpdated review to date in topical rapamycin for facial angiofibromas, allowing support in therapeutic decisions.
