Introduction: Ellis-van Creveld (EVC) syndrome is an autosomal recessive disorder predominantly characterized by a disproportionate dwarfism, ectodermal dysplasia, postaxial polydactyly, and congenital heart malformations and pulmonary hypoplasia.
Objective: In this article, we hereby present a case of a 6-year-old Brazilian boy with EVC syndrome who presented a rare oral lesion as well as a remarkable number of classical and uncommon oral and dental features.
Case report: Clinical and radiographic examination revealed multiple enamel hypoplasia, teeth agenesis, conical teeth, lower canine rotation, bilateral posterior crossbite, taurodontism of deciduous and permanent molars and delayed tooth eruption, dental caries, and absent vestibular sulcus. Additionally, a whitish lobulated nodule located in the alveolar ridge in the anterior region of the mandible was noted. Anatomopathological examination was compatible with the diagnosis of peripheral odontogenic fibroma (POF). In a 10-month clinical follow-up, no signs of recurrence were observed.
Conclusion: In view of the characteristic oral findings of EVC syndrome and the potential for recurrence of POF, the pediatric dentist plays an essential role in clinical follow-up, planning and preventive, and rehabilitative treatment.
