Background: Dermoid cysts are rare congenital lesions derived from pluripotential cells.
Case presentation: We present a case of a female patient aged 30 years presenting for a lesion of the mandibula incidentally seen on a routine panoramic radiograph obtained for dental care. The instrumental, clinical and histological characteristics of the lesion are reported. Finally, a bibliographic revision of this pathology at the level of the oral cavity is reported.
Conclusion: Dermoid cysts must be considered in the differential diagnosis of mandibula's lesions.
