Abstract
Pseudotumor is a rare complication of hemophilia with a prevalence 1–2% of all clinical cases. Commonly bone lesions affect long tubular bones, the pelvis, wrist and foot bones. According to world science literature only 16 cases of maxilla bone lesions in patients with hemophilia were found. This article describes a clinical case of maxilla pathological lesion with the destruction of facial skeleton bones in a one year old boy. The differential diagnosis included malignant and benign neoplasia, inflammatory processes. During laboratory examination a deficiency of IX coagulation factor was revealed and the patient was diagnosed with hemophilia В. The patient underwent surgical treatment by removing the lesion with specific replacement therapy; an intraosseous organizing hematoma was verified. The maxilla pseadotumor in this child was a manifestation of hemophilia. The patient's parents agreed to use the information, including the child's photo, in scientific research and publications.
