Hemophilic pseudotumor is a rare complication occurring in 1–2% of cases and resulting from a recurrent chronic muscle hematoma. We describe a clinical case of a child suffering from hemophilia type A who was admitted with a forearm mass, interpreted as a pseudotumor. However, histological examination of the mass revealed a rare aggressive CIC-rearranged sarcoma. The patient's parents gave consent to the use of their child's data, including photographs, for research purposes and in publications.

Развитие псевдоопухоли является редким осложнением у пациентов с гемофилией, которое встречается в 1–2% случаев и является следствием хронической мышечной гематомы. Мы представляем описание клинического случая ребенка, страдающего гемофилией А, поступившего с образованием предплечья, трактуемым как псевдоопухоль. Однако при гистологическом исследовании образования выявлена высокозлокачественная редкая опухоль – СIC-перестроенная саркома. Родители пациента дали согласие на использование информации, в том числе фотографий ребенка, в научных исследованиях и публикациях.
