Osteosarcoma is high-grade tumor of skeleton and compose 6% of all bones tumors and bone dysplasia, 62% of malignant tumors of bones and 18% of all malignancies in children. Approximately 80% of the metastases are localized in the lungs, metastasis only in the bones, or both in bones and lungs observed in 20% of patients. Patient underwent neoadjuvant and adjuvant chemotherapy and surgery – extirpation of the right calcaneus with the replacement of the defect with thoracodorsal flap.</p></abstract><trans-abstract xml:lang="ru"><p>Данная статья посвящена демонстрации клинического случая пациента с остеосаркомой редкой локализации. Остеосаркома относится к высокозлокачественным опухолям скелета и составляет до 6% от всех костных опухолей и дисплазий, 62% от злокачественных опухолей костей и 18% всех злокачественных опухолей у детей. Примерно в 80% случаев метастазы локализуются только в легких, метастазирование только в кости или одновременно в кости и легкие наблюдается у 20% больных. Пациенту выполнены адъювантная и неоадъювантная полихимиотерапия и оперативное лечение – экстирпация правой пяточной кости с замещением дефекта торакодорсальным лоскутом.</p></trans-abstract><kwd-group xml:lang="en"><kwd>osteosarcoma</kwd><kwd>calcaneus</kwd><kwd>chemotherapy</kwd><kwd>surgery</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>остеосаркома пяточной кости</kwd><kwd>химиотерапия</kwd><kwd>оперативное лечение</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
