There are few data in the literature on the incidence of this disease, as well as clinical recommendations for treatment.</p> <p><bold>Clinical case.</bold> This report presents the case of an 11.5-year-old boy with primary tumoral calcinosis and equinus deformity of the foot. The patient had multiple foci of the subcutaneal calcification, cannot walk, experienced fatigue, and had high fever and equinus deformity of the left foot. Immunological and genetic studies were performed, but any specific mutations were not found. After the diagnosis was verified and interleukin-1β inhibitor therapy was prescribed, there was a significant positive trend observed in the patient: a significant improvement in the patient’s general condition, a decrease in the number of calcinates, and a reduction in inflammation. Calcification of the Achilles tendon and gastrocnemius muscle was the cause of the deformity of the left foot.</p> <p><bold>Discussion.</bold> Significant improvement was achieved during treatment: the boy started walking, fatigue was decreased, no new calcificates were formed, and inflammation was under the control. Using an inhibitor of interleukin-1β as a permanent therapy of primary tumoral calcification allowed performsurgical treatment without complications from an operation site, as well as a relapse of deformity.</p> <p><bold>Conclusion.</bold> The clinical case presented here demonstrated the application of an interdisciplinary approach to the treatment of an extremely rare disease.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Первичный опухолевый кальциноз является крайне редким заболеванием. Статистические данные о встречаемости данной патологии, а также клинические рекомендации по лечению в русскоязычной литературе отсутствуют.</p> <p><bold>Клиническое наблюдение.</bold> Представлен клинический случай лечения пациента 11,5 года с первичным опухолевым кальцинозом и эквинусной деформацией левой стопы. Ребенок поступил с жалобами на наличие множественных подкожных кальцинатов, невозможность самостоятельно ходить, утомляемость, подъем температуры до фебрильных цифр, деформацию левой стопы. Проведен комплекс клинико-лабораторного, иммунологического и генетического обследования. После установки диагноза и назначения терапии ингибитором интерлейкина-1β отмечена значительная положительная динамика: общее состояние пациента существенно улучшилось, уменьшилось количество кальцинатов, были купированы воспалительные явления. При обследовании обнаружено, что деформация левой стопы обусловлена кальцификацией ахиллова сухожилия и икроножной мышцы. Для лечения деформации стопы было успешно применено хирургическое лечение.</p> <p><bold>Обсуждение.</bold> В результате комплексного подхода к лечению достигнуто значимое клиническое улучшение. Ребенок самостоятельно ходит, прекратилось образование новых кальцинатов, снизилась утомляемость, был купирован воспалительный процесс. Благодаря применению ингибитора интерлейкина-1β в качестве постоянной терапии первичного опухолевого кальциноза удалось выполнить хирургическое лечение без осложнений со стороны послеоперационной раны, а также предотвратить рецидив деформации.</p> <p><bold>Заключение.</bold> Представленный клинический случай демонстрирует применение междисциплинарного подхода к лечению крайне редкого заболевания. При отсутствии клинических рекомендаций по лечению и диагностике первичного опухолевого кальциноза верификация правильного диагноза и применение комплексного лечения позволили добиться значительного улучшения качества жизни пациента. Мы считаем необходимым сообщить не только о новых эффективных методах лечения, но и информировать специалистов о клинической картине столь редкого заболевания.</p></trans-abstract><trans-abstract xml:lang="zh"><p><bold>引言：</bold>原发性肿瘤样钙质沉着症是一种罕见病。鲜少有文献探讨该病的发生率及临床治疗建议。</p> <p><bold>临床病例：</bold>本报告报道了1例11.5岁男性患儿，其患有原发性肿瘤样钙质沉着症和单侧马蹄足畸形。患者有多发性皮下钙化病灶，无法行走，出现疲乏和高烧，左足马蹄状畸形。已行相关免疫学和遗传学检查，但尚未发现具体突变基因。确诊后给予白细胞介素-1β抑制剂，用药后观察到明显积极的趋势：患者整体状况明显好转，钙化明显减少，炎症有所缓解。左足畸形的病因是跟腱及腓肠肌钙化。</p> <p><bold>讨论：</bold>治疗后病情明显改善：患儿能开始行走，疲乏减退，未见新发钙化形成，炎症得以控制。将白细胞介素-1β抑制剂作为原发性肿瘤样钙化的永久治疗手段，使手术部位无任何并发症，同时预防畸形复发。</p> <p><bold>结论：</bold>本研究所述的临床病例展示了极罕见病跨学科治疗方法的应用过程。</p></trans-abstract><kwd-group xml:lang="en"><kwd>primary tumor calcification</kwd><kwd>tumoral calcification</kwd><kwd>familial tumoral calcification</kwd><kwd>hyperphosphatemic hyperostosis syndrome</kwd><kwd>canakinumab</kwd><kwd>equinus deformity</kwd><kwd>clinical case</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>первичный опухолевый кальциноз</kwd><kwd>туморальный кальциноз</kwd><kwd>семейный туморальный кальциноз</kwd><kwd>гиперфосфатемический гиперостоз-синдром</kwd><kwd>ингибитор интерлейкина-1β</kwd><kwd>канакинумаб</kwd><kwd>эквинусная деформация</kwd><kwd>клинический случай</kwd></kwd-group><kwd-group xml:lang="zh"><kwd>原发性肿瘤样钙化</kwd><kwd>肿瘤样钙化</kwd><kwd>家族性肿瘤样钙化</kwd><kwd>高磷血症骨质增生综合征</kwd><kwd>卡那 单抗</kwd><kwd>马蹄状畸形</kwd><kwd>临床病例。</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Russian Foundation for Basic Research</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Российский фонд фундаментальных исследований</institution></institution-wrap></funding-source><award-id></award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>McClatchie S, Bremner AD.
