Since the natural progression of infantile hemangiomas is typically benign, over 90 % of cases do not require medical intervention. However, treatment is necessary for infantile hemangiomas that present local complications, functional impairments, or a risk of disfigurement. In this article we presented two children with mixed and deep infantile hemangiomas, with satisfactory therapeutic responses after treatment with topical timolol maleate. <italic>Conclusion.</italic> Timolol maleate is an effective, well-tolerated, and safe treatment option for various types of infantile hemangiomas.</p></abstract><trans-abstract xml:lang="ru"><p style="text-align: justify;"><italic>Актуальность</italic>. Инфантильные гемангиомы являются наиболее распространенными сосудистыми опухолями у детей. Поскольку естественное развитие инфантильных гемангиом обычно доброкачественное, более 90 % случаев не требуют медицинского вмешательства. Однако лечение необходимо для инфантильных гемангиом, которые представляют местные осложнения, функциональные нарушения или риск обезображивания. Мы представили двух детей со смешанными и глубокими инфантильными гемангиомами с удовлетворительными терапевтическими ответами после лечения топическим тимолола малеатом. Выводы. Тимолола малеат является эффективным, хорошо переносимым и безопасным вариантом лечения различных типов инфантильных гемангиом.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hemangioma</kwd><kwd>timolol</kwd><kwd>propranolol</kwd><kwd>topical</kwd><kwd>treatment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>гемангиома</kwd><kwd>тимолол</kwd><kwd>пропранолол</kwd><kwd>местный</kwd><kwd>лечение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Krowchuk DP, Frieden IJ, Mancini AJ, Darrow DH, Blei F, Greene AK, Annam A, Baker CN, Frommelt PC, Hodak A, Pate BM, Pelletier JL, Sandrock D, Weinberg ST, Whelan MA.
