Odontogenic myxomas are rare tumour that involve the mandible or maxilla and account for 3-6% of odontogenic tumours 2.
Typically seen in the 2nd to 3rd decades of life (slightly earlier than ameloblastomas). They are usually not painful.
Arises from mesenchymal odontogenic tissue.
The radiographic appearance is very similar to that of an ameloblastoma : a "soap bubble" lytic septated cystic lesion of the mandible.
Treatment and prognosis
Wide marginal excision is the treatment of choice. Local recurrence can occur.
