Osteosarcoma is the most common primary malignant neoplasm of bones in children; this tumor accounts for 50 to 80% of all skeletal sarcomas. Less often, osteosarcoma affects flat bones (scapula, ribs, bones of the skull and pelvis), bones of the foot, hand and spine. Description of the observation. A 13-year-old girl, 8 months before admission to the clinic, began to complain of pain in her right hand, six months later, a swelling appeared in this area. After radiography, which revealed a bone tumor of the III metacarpal bone, a trepanobiopsy with histological examination was performed. Conclusion: subperiosteal telangiectatic osteosarcoma G II. The child was admitted to the oncology department in November 2018. Before the operation, the girl underwent 4 courses of chemotherapy, as a result of which the tumor reduced in size, which made it possible to perform organ-preserving surgical treatment extirpation of the third metacarpal bone affected by the tumor, followed by autoplasty from the wing of the right iliac bone with fixation of the graft Kirschner needles. The postoperative period passed without complications. As a result of the operation, it was not only possible to radically remove the tumor, but also to preserve 3 fingers of the right (working) hand with good functionality. After surgery, the child received 5 courses of polychemotherapy and is currently in remission. Conclusion. The above observation demonstrates the possibility of performing organ-preserving surgeries using bone autoplasty for rare tumor lesions of the metacarpal bones. This method is more physiological in comparison with the use of allo- or artificial grafts.
М. А. Воробьева и др. Случай серозного менингита ротавирусной этиологии у четырехлетнего ребенка 12. Liu B., Fujita Y., Arakawa C., Kohira R., Fuchigami T., Mugishima H., Kuzuya M. Detection of rotavirus RNA and antigens in serum and cerebrospinal fluid samples from diarrheic children with seizures. 1 Научно-практический центр специализированной медицинской помощи детям им. Войно-Ясенецкого, Москва, РФ 2 Морозовская детская гродская клиническая больница, Москва, РФ В статье приводится описание клинического случая инфантильного миофиброматоза у новорожденного ребенка. Инфантильный миофиброматоз -редко встречающаяся мезенхимальная опухоль мягких тканей головы, конечности, туловища у детей, обладающая местным инфильтративным ростом без метастазов. В ходе обследования данного пациента были диагностированы множественные миофибромы, имевшие тенденцию к росту в сочетании с активной герпесвирусной инфекцией. В данном случае не исключается влияние смешанной герпетической инфекции на рост миофибром, так как на фоне противовирусного лечения была получена положительная динамика с уменьшением количества и размеров новообразований. Ключевые слова: инфатильный миофиброматоз, миофиброма, новорожденный, герпесвирусная инфекция
