- Abstract: Tuberous sclerosis complex (TSC) is an autosomal dominant neurocutaneous disorder with an incidence of approximately 1 in 5,000 to 10,000 live births. TSC has various clinical manifestations such as multiple hamartomas in systemic organs, including the skin. Angiofibromas are the most common skin lesions in patients with TSC. Although benign, angiofibromas develop in childhood and puberty, and can be psychosocially disfiguring for patients. Skin lesions in TSC, specifically angiofibromas, have no significant risk of malignant transformation after puberty; thus, they require no treatment if not prominent. However, the presentation of TSC is important owing to its impact on patient cosmesis. Surgical treatment and laser therapy are the mainstream treatments for angiofibromas. Although the evidence is limited, topical mammalian target of rapamycin inhibitors such as sirolimus (rapamycin) are effective in facial angiofibroma treatment. We describe an adult patient with an angiofibroma who had an excellent response to treatment with topical rapamycin after a single session of carbon dioxide (CO₂) laser ablation. The patient showed no sign of relapse or recurring lesions for a year. CO₂ laser ablation may serve as a new paradigm of treatment for angiofibromas in TSC. Since the selection of laser devices can be limited for some institutions, we suggest a rather basic but highly effective approach for angiofibroma treatment that can be generally applied with the classic CO₂ device.
