Ossifying fibroma is a rare benign osteogenic neoplasm arising from undifferentiated cells of the periodontal ligament and with a potential to form fibrous tissue, cementum and bone, which is usually in molar area of the mandible, predominantly seen in young girls. And ossifying fibroma poses diagnostic and therapeutic difficulties due to their clinical, radiological and histological variabilities. We report a rare case of an 18 year old girl with cystic degeneration of ossifying fibroma in maxilla which is an uncommon site of occurrence.
骨化性纤维瘤是一种罕见的良性成骨性肿瘤，起源于牙周膜的未分化细胞，具有形成纤维组织、牙骨质和骨的潜能，通常发生在下颌磨牙区，多见于年轻女性。由于其临床、影像学和组织学的变异性，骨化性纤维瘤在诊断和治疗上存在困难。我们报告一例罕见病例，一名18岁女孩上颌骨骨化性纤维瘤发生囊性变，而上颌骨是其不常见的发病部位。
