Management of a Pediatric Oral Hemangioma Using Intralesional Sodium Tetradecyl Sulfate: A Case ReportKey Clinical Message: Benign vascular lesions called oral hemangiomas are frequently seen in young children. In this case study, intralesional sodium tetradecyl sulfate (STS) was used successfully to treat a 10-year-old girl who had an oral hemangioma. The lesion was noted a few weeks after birth, which was located on maxillary labial and vestibular mucosa from teeth 12 to 16 with effacement of right nasolabial fold. Diagnosis was confirmed through ultrasonography and contrast enhanced computer tomography imaging. The patient had intralesional STS injections several times, which significantly decreased the size of the lesion and eliminated the related symptoms. The effectiveness of STS as a non-surgical therapy option for children’s oral hemangiomas is demonstrated by this report.
