Successful Treatment of Macroglossia Due to Lymphatic Malformation With Sirolimus

Abstract

OBJECTIVE: To evaluate the effectiveness and safety of sirolimus therapy in a child with macroglossia due to lymphatic malformation. METHODS: Sirolimus treatment was applied to the patient with an initial dosing of 0.8 mg/m2 per dose, administered orally, twice daily at approximately 12-hour intervals. RESULTS: After 9 months of sirolimus therapy, there was a nearly complete resolution of lymphatic malformation. The last evaluation was performed 6 months after withdrawal of treatment, and the lesion had almost completely resolved. CONCLUSION: This article presents a novel approach to the treatment of lymphatic malformation of the tongue using sirolimus, which appears to be safe and effective for the management of complex cases.
