Опухоль возникает из подкожной клетчатки и наиболее часто обнаруживается в подмышечной впадине, затем в плечевой, паховой областях и грудной стенке. Характерным микроскопическим видом ФГМ является наличие 3 типов тканей в различных пропорциях: четко очерченные пучки плотной волокнистой соединительной ткани, примитивной мезенхимы (организованной в гнездах, концентрических завитках или полосах) и промежуточной зрелой жировой ткани. Хирургическое удаление является основным методом выбора лечения при данной патологии. Мы сообщаем о 2 случаях редкого расположения ФГМ, локализующихся в ягодичной области и области задней верхней трети бедра. При этом в одном наблюдении поражение затрагивало только подкожно-жировую клетчатку, а во втором отмечался распространенный инвазивный процесс в мышцах. Несмотря на доброкачественный характер опухоли, распространение ее характеризуется инвазивным ростом (не имеет капсулы и четкой границы с окружающими тканями), что может вызвать трудности у хирургов при первичной операции в определении границ удаления ФГМ. Считаем целесообразным использовать для этого экспресс-биопсию во время оперативного вмешательства.</p></abstract><trans-abstract xml:lang="en"><p>Fibrous hamartoma of infancy (FHI) is a rare tumor, accounting for less than 2% of soft tissue tumors occurring in the first year of life. The tumor arises from the subcutaneous tissue and is most often found in the armpit, then in the shoulder, groin and chest wall. The characteristic microscopic appearance of FHI is the presence of three tissue types in varying proportions: well-defined bundles of dense fibrous connective tissue, primitive mesenchyme (organized in nests, concentric whorls, or bands), and intermediate mature adipose tissue. Surgical removal is the main choice of treatment for this pathology. We report 2 cases of rare FHI localized in the gluteal region and the region of the posterior upper third of the thigh. At the same time, in one observation, the lesion affected only the subcutaneous fat, and in the second, a widespread invasive process in the muscles was noted. Despite the benign nature of the tumor, its spread is characterized by invasive growth (it does not have a capsule and a clear border with the surrounding tissues), which can cause difficulties for surgeons during the primary operation in determining the boundaries of FHI removal. For this purpose, we consider it expedient to use an express biopsy during surgery.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фиброзная гамартома младенцев</kwd><kwd>дети</kwd><kwd>оперативное лечение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>fibrous hamartoma of infancy</kwd><kwd>children</kwd><kwd>surgical treatment</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Reye R.D.
