Juvenile ossifying fibroma (JOF) is an expansile intra-osseous lesion of the jaw that emulate odontogenic lesions frequently seen in patients under 15 years of age. They are histologically characterized by the presence of fibrous stromal cells along with mineralized tissues. Clinically, these are characterized by early age of onset, histological patterns, high rate of recurrence and the aggressive local behavior. The differential diagnosis of JOF with other fibro-osseous lesions of the jaw should be made along with an essential microscopic examination and be largely based on the character of the calcified products of the tumor. The purpose of this article is to present a rare clinical case of the trabecular type of JOF and to describe its clinical, radiological and histological characteristics. The clinician should be aware of this type of lesion in order to be able to distinguish this it from other fibrous lesions if encountered in routine practice and for appropriate treatment to be carried out.
青少年骨化性纤维瘤（JOF）是颌骨内一种具有膨胀性的病变，常类似15岁以下患者常见的牙源性病变。其组织学特征为存在纤维基质细胞以及矿化组织。临床上，这些病变的特点是发病年龄早、组织学模式、高复发率和侵袭性局部行为。JOF与颌骨其他纤维-骨病变的鉴别诊断应结合必要的显微镜检查，并且很大程度上基于肿瘤钙化产物的特征。本文的目的是呈现一例罕见的小梁型JOF临床病例，并描述其临床、放射学和组织学特征。临床医生应了解这种类型的病变，以便在日常实践中遇到时能够将其与其他纤维性病变区分开来，并进行适当的治疗。
