This is a case report of an unusual odontogenic myxoma with calcifications, one of three reported in the literature. It had a typical radiographic appearance although it presented in an older patient. The presence of osteo-cementum-like calcification raises other differential diagnoses but does not in and of itself mitigate the diagnosis. The patient has not shown recurrence 14 months after resection and 11 months after reconstruction and continues to be closely monitored.
