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.
