ABSTRACT
Introduction: Exostoses are localized bony lumps of a benign nature. They are an
infrequent condition in infants.
Objective: Present a case of bilateral palatal exostosis in a dark-skinned female infant aged
one year and four months.
Case presentation: The girl was brought by her mother to the Children's Dental Clinic for
oral examination. During anamnesis, the mother referred to delay in the eruption of
deciduous teeth and the presence of lumps on the upper arch without any painful symptom.
She also reported that three relatives had the same alteration in their maxilla or mandible.
Oral examination revealed a bilateral flat bony lump in the maxilla, in the lingual region of
the palatal tuberosities, covered by normal oral mucosa. The surface was stiff to palpation
with well defined borders. The genetic factor was associated to the clinical aspect of the
lesion, as well as the sex and ethnicity of the patient. The diagnosis was bilateral palatal
exostosis. Biopsy and active treatment for removal of the lesion were not justified due to the
patient's age, absence of painful symptoms, and potential interference with feeding,
swallowing and other oral functions. The patient was periodically followed-up and was
observed to present a normal process of deciduous tooth eruption.
Conclusions: Even though palatal exostosis is infrequent in children, it is important for
dental surgeons to be knowledgeable about the topic so as to reach an appropriate diagnosis
and treatment plan.
