Abstract

A 16-year-old male patient, with Crouzon syndrome and severe bone deformity was referred to a hospital after an orthodontics evaluation, which detected a hyperdense circumscribed image in the maxilla during a facial computed tomography examination. The patient had anosmia and clinically a slight painless bulging in the anterior maxilla. An excisional biopsy with peripheral osteotomy was performed and the material was sent for histopathological analysis with under hypothesis of osteoma or fibrous dysplasia. Microscopically, there were benign fibro-osseous lesions characterized by hypercellular fibrous connective tissue, containing multiple ossicles with variable sizes and shapes, from spherical, oval to irregular and eosinophilic, with few basophilic areas similar to calcification, many with a brush border. Vital bone trabeculae were observed bordering the lesion and erythrocyte extravasation was compatible with psammomatoid juvenile ossifying fibroma. There was no need for further treatment and the patient remains under oral and maxillofacial follow-up for future orthognathic surgery.

一名患有克鲁宗综合征和严重骨骼畸形的 16 岁男性患者在接受牙齿矫正评估后被转诊到一家医院,在面部计算机断层扫描检查中发现上颌骨有一个高密度的环形图像。患者无嗅,临床上上颌骨前部有轻微无痛性隆起。医生对患者进行了切除活检和周边截骨术,并将材料送去进行组织病理学分析,假设为骨瘤或纤维发育不良。显微镜下可见良性纤维骨病变,其特点是纤维结缔组织细胞增生,内含多个骨小梁,大小和形状不一,有球形、椭圆形和不规则形,嗜酸性,有少量类似钙化的嗜碱性区域,许多骨小梁有刷状缘。在病变周围可观察到有活力的骨小梁,红细胞外渗与脓疱型幼年骨化性纤维瘤相符。患者无需进一步治疗,目前仍在接受口腔颌面部随访,以便将来进行正颌手术。
