Osteoma cutis (OC) is a rare benign disorder where osseous nodules form in the reticular layer of normal skin. These nodules are formed by the deposition of lamellar bone and are characterized by osteocytes in the core and osteoclasts around the periphery. Interpretation of osteoma cutis cases has always been challenging especially using conventional two-dimensional (2D) radiographs, owing to difficulty in localization. Cone beam CT (CBCT), with its three-dimensional (3D) capabilities, offers a great tool to help detect and diagnose these calcific entities. We report a case of miliary type OC incidentally detected in the maxillofacial region using CBCT imaging.
皮肤骨瘤（OC）是一种罕见的良性疾病，在正常皮肤的网状层形成骨结节。这些结节由板层骨沉积形成，其特征是核心有骨细胞，周边有破骨细胞。由于定位困难，对皮肤骨瘤病例的解读一直具有挑战性，尤其是使用传统的二维（2D）X线片时。锥形束CT（CBCT）具有三维（3D）成像能力，为检测和诊断这些钙化实体提供了一个很好的工具。我们报告一例使用CBCT成像在颌面部偶然发现的粟粒型OC病例。
