Infantile hemangioma is one of the most common benign vascular malformations in children. Besides that, some questions about classification, diagnostic, and choice of method of treatment remains the questionable. The modern data about classification, clinical course, diagnostic, and main principles of treatment of infantile hemangioma are presented in this work. In most cases, the uncomplicated clinical course of infantile hemangioma was observed. However, in some patients the complications may arise. Ulceration, obstruction, functional impairment, and disfigurement are the most often complications of infantile hemangioma. Although, most infantile hemangiomas tend to regress spontaneously, some of them required the treatment. Applying of the β-blockers (systemic or topical), laser therapy, and surgery are the main methods that used for the treatment of infantile hemangiomas. Patients with infantile hemangiomas, despite the simplicity of diagnostic, should be treated on specialized centers. Early detection of at-risk infantile haemangioma is a major point, requiring an increased awareness by paediatricians, with the aim to prevent the complications development. However, it was proven the efficacy of propranolol treatment for the all types of infantile hemangiomas, the long-term follow-up studies are needed to assess its safety with regard to neurodevelopment. No conflict of interest was declared by the authors. Key words: infantile hemangioma, diagnostic, treatment.
