Опухоли секретируют фактор роста фибробластов 23 (ФРФ23), который обладает фосфатурическим действием. Клинические симптомы онкогенной остеомаляции неспецифичны (включая утомляемость, боли в костях и мышечную слабость), что затрудняет своевременную постановку диагноза и приводит к задержке лечения.</p><p>При своевременной диагностике и полной резекции образования прогноз благоприятный и приводит к полному нивелированию симптомов. В случае отсутствия визуализации опухоли используется консервативное лечение препаратами фосфора и активных метаболитов витамина D. Из-за риска рецидива или метастазирования ФРФ23-секретирующих образований пациенты требуют длительного мониторинга.</p><p>В статье представлен клинический случай поэтапной диагностики и лечения фосфопенической остеомаляции опухолевого генеза у пациентки молодого возраста с сахарным диабетом 1 типа.</p></abstract><trans-abstract xml:lang="en"><p>Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome usually caused by small-sized tumors. Tumors secrete fibroblast growth factor 23 (FGF23), which has a phosphaturic effect. The clinical signs of TIO are non-specific, and include fatigue, bone pain and muscle weakness, which makes timely diagnosis of the disease difficult and treatment is often delayed.</p><p>Well-timed diagnosis is essential and combined with complete tumor resection it leads to complete relief of symptoms and good postoperative prognosis. In cases of undetected tumors, medical treatment with phosphate supplements and active vitamin D medications is usually successful, however, treatment is associated with numerous complications and side effects can be burdensome for the patients. Due to the risk of recurrence or metastasis, patients with TIO require long-term management and follow-up.</p><p>In this article, we present a clinical case of successful diagnosis and treatment of TIO in a young patient with type 1 diabetes mellitus.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гипофосфатемия</kwd><kwd>онкогенная остеомаляция</kwd><kwd>фактор роста фибробластов 23</kwd><kwd>фосфор</kwd><kwd>мезенхимальная опухоль</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypophosphatemia</kwd><kwd>tumor-induced osteomalacia</kwd><kwd>fibroblast growth factor-23</kwd><kwd>mesenchymal tumor</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">Bhatt AA, Mathews SS, Kumari A, Paul TV.
