Recurrent Maxillary Odontogenic Myxoma Following Partial Maxillary Resection and Consecutive Osseous Reconstruction Including Tooth Transplantation

摘要

Odontogenic myxoma (OM) is a rare tumour arising in the jaws. The tumour is purported to be odontogenic in origin due to the frequent localisation of the tumour inside the jaws in close relation to teeth. The aim of this report was to detail the course of a patient who developed OM of the maxilla, underwent adequate ablative surgery and reconstruction, including tooth transplantation to the original tumour site, and subsequently developed a local recurrence in close proximity to the teeth transplanted to the reconstructed maxilla 6 years after the first diagnosis. Once again, a partial maxillary resection was performed, with no reconstruction. The patient has been free from tumour recurrence for over 20 years. We discuss the current hypothesis on OM pathogenesis and the possible impact of actively dividing cells on tumour re-growth.
