Odontogenic Myxoma
Pronunciation: oh-don-toe-JEN-ik mik-SOH-mah
Benign but locally aggressive jaw tumor arising from odontogenic mesenchyme.
Full Definition
Odontogenic myxoma is a rare benign tumor that develops from the mesenchymal components of the tooth-forming apparatus. Despite being histologically benign, these tumors are locally aggressive with a high recurrence rate if incompletely excised. They typically occur in the posterior mandible and present as multilocular radiolucent lesions with characteristic soap-bubble or honeycomb radiographic patterns. Treatment requires wide excision with clear margins, often necessitating significant bone removal and subsequent reconstruction. The tumor's gelatinous consistency can make complete removal challenging.
Usage
Usage note: High recurrence potential requires long-term follow-up and imaging surveillance.
