Abstract

Introduction: In children, and specifically in infants, odontogenic myxomas are extremely rare. In infants, myxoma seems to display mostly the same clinical, radiological and pathological characteristics. This paper presents a series of odontogenic myxomas in infant patients.

Materials and methods: Four infant patients were included in this retrospective study. The clinical, radiological and pathological presentation was characterized and the treatment analysed.

Results: All patients presented with a rapidly evolving paranasal swelling. CT-scan showed a maxillary homogeneous unilocular and intraosseous tumour. In all cases, pathological examination revealed a loose myxoid stroma within stellate and spindle shaped cells. All patients underwent conservative surgery through a vestibular approach.

Conclusion: This patient series and a review of the literature demonstrates that odontogenic myxoma is specific in infant. We propose the name of Infant Odontogenic Myxoma for this entity.

Keywords: Infant; Jaw tumours; Myxoma; Myxomatous tumours; Odontogenic myxoma; Odontogenic tumours.
