The calcifying epithelial odontogenic tumour (CEOT) is an extremely rare benign neoplasia, accounting for approximately 1% of all odontogenic tumours. CEOT can have two clinical manifestations: central or intraosseous (94% of the cases) and peripheral or extraosseous (6% of the cases). Although the latter is less common, the peripheral variant has been described as an insidious lesion, since it is usually asymptomatic and may be erroneously mistaken with gingival hyperplasia, hamartomas, or even metastasis of malignant neoplasia. We report a case of a young male patient presenting with a peripheral CEOT in the mandibular posterior region, mimicking a located gingival inflammation.
牙源性钙化上皮瘤（CEOT）是一种极其罕见的良性肿瘤，约占所有牙源性肿瘤的1%。CEOT可有两种临床表现：中心型或骨内型（94%的病例）和外周型或骨外型（6%的病例）。尽管后者较少见，但外周型变异型被描述为一种隐匿性病变，因为它通常无症状，可能被误诊为牙龈增生、错构瘤，甚至恶性肿瘤转移。我们报告一例年轻男性患者，在下颌后部出现外周型CEOT，酷似局限性牙龈炎症。
