According to the WHO, JOF may present as one of two histologic variants: juvenile psammomatoid ossifying fibroma (JPOF) and juvenile trabecular ossifying fibroma (JTOF). Radiographycally, JOF presents as a well defined, unilocular or multilocular, expansive radiolucency with cortical thinning. The definitive diagnosis of JOF should be based on clinical and radiographic findings, in conjunction with the histopathologic characteristics of the lesion.</p></abstract><trans-abstract xml:lang="ru"><p>Ювенильная оссифицирующая фиброма (ЮОФ) объединяет группу гетерогенных доброкачественных костно-фиброзных опухолей челюстно-лицевого скелета у детей и подростков. Соответственно классификации ВОЗ выделяются два основных гистологических варианта строения опухоли: трабекулярный и псаммоматоидный. Диагноз оссифицирующей фибромы может быть поставлен на основании четкого очертания очага поражения, что отражается на рентгенологических снимках и проявляется во время операции. Характер костеобразования при псаммоматоидном варианте опухоли имеет ряд диагностических особенностей. Дополнительные иммуногистохимические методы не позволяют достоверно различить ювенильную оссифицирующую фиброму от псаммоматоидной менингиомы и фиброзной дисплазии. Диагноз устанавливается при сопоставлении клинических и рентгенологических данных в сочетании с гистопатологическими характеристиками опухоли.</p></trans-abstract><kwd-group xml:lang="en"><kwd>juvenile ossifying fibroma</kwd><kwd>fibrous dysplasia</kwd><kwd>meningioma</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ювенильная оссифицирующая фиброма</kwd><kwd>фиброзная дисплазия</kwd><kwd>менингиома</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
