Benign osteoblastoma (OB) is a rare tumor of bone representing less than 1% of all tumors of the maxillofacial region. Vertebral column, sacrum, long bones, and calvarium are more frequent sites of this tumor. Clinically, patients present with pain and swelling. Histologically, contain a well vascularized, osteoblastic connective tissue stroma and occasionally, osteoclasts along with osteoid and varying degrees of calcification, as well as immature bone may also be noted. The main aim of this report is present a case of OB occurring in the mandible and a brief review of English Medical Literature of this tumor. Many bone-producing lesions possess some overlapping clinical, radiographic or histopathological findings similar to osteoblastoma. Understanding and correlating all features helps in correct diagnosis and adequate management of this rare entity. Hence, osteoblastoma has to be differentiated from other bone lesions for correct diagnosis.
骨母细胞瘤（OB）是一种罕见的骨肿瘤，在所有颌面部肿瘤中占比不到1%。脊柱、骶骨、长骨和颅骨是该肿瘤更常见的发病部位。临床上，患者表现为疼痛和肿胀。组织学上，其包含血管丰富的成骨细胞性结缔组织基质，偶尔可见破骨细胞，同时伴有类骨质和不同程度的钙化，也可能观察到未成熟骨。本报告的主要目的是呈现一例发生在下颌骨的骨母细胞瘤病例，并对该肿瘤的英文医学文献进行简要综述。许多骨生成性病变具有一些与骨母细胞瘤相似的重叠临床、影像学或组织病理学表现。理解并关联所有特征有助于对这一罕见疾病进行正确诊断和适当管理。因此，为了正确诊断，骨母细胞瘤必须与其他骨病变相鉴别。
