Keratocystic odontogenic tumor (KCOT) is a benign odontogenic tumor with a potentially aggressive and infiltrative behavior. KCOT is most commonly occurred in mandible and demonstrate a unilocular, round, oval, scalloped radiolucent area, while large lesions may appear multilocular. An important characteristic of KCOT is its propensity to grow in an antero-posterior direction within medullary cavity of bone causing minimal expansion. Definitive diagnosis relies on histological examination. In this report, a KCOT that had an expansion both buccal and lingual cortical bone is described including its features in computed tomography and ultrasonographic exams. The lesion was removed surgically via an intraoral approach under local anesthesia and histologically reported as a KCOT.
牙源性角化囊性瘤（KCOT）是一种具有潜在侵袭性和浸润性的良性牙源性肿瘤。KCOT最常发生于下颌骨，表现为单房、圆形、椭圆形、扇贝样的透射区，而较大的病变可能呈多房性。KCOT的一个重要特征是其倾向于在骨髓腔内沿前后方向生长，导致骨膨胀最小。明确诊断依赖于组织学检查。在本报告中，描述了一例颊侧和舌侧皮质骨均有膨胀的KCOT，包括其在计算机断层扫描和超声检查中的特征。该病变在局部麻醉下经口内入路手术切除，组织学报告为KCOT。
