Infantile hemangioma is the most common anomalies affecting young children. This disease occurs in 2—9% of newborns. Before laser therapy and the discovery of propranolol’s properties, sclerotherapy, close-focus X-ray therapy, and other crippling, low-efficacy methods were widespread. After their use, patients needed additional reconstructive surgical treatment and psychological help. This article presents a clinical case of the treatment of patient K., 6 years old, who underwent a single close-focus radiotherapy at the age of 9 months. The aesthetic result of the intervention was unsatisfactory, and treatment with propranolol was contraindicated due to somatic complications. Doppler ultrasound, transcutaneous oxygenometry, and formation thermometry were used for diagnosis. At the age of 3, a child underwent interstitial coagulation of hyperplastic vessels using a laser with a wavelength of 970 nm. At the age of 5.5 years, the second stage of treatment was performed — surgical removal of a residual hemangioma with scarred tissues. Histological examination showed increased expression of glucose transporter protein GLUT1 in the vascular wall, which is typical for infantile hemangioma. Six months after the end of treatment, a normotrophic, mild postoperative scar was observed, the anatomy of the upper lip was restored, the lip was soft and elastic.
