Recurrent ameloblastoma in an autogenous bone graft after 28 years: a case report.

The growth characteristics of ameloblastoma is such that recurrence can occur regardless of treatment method, although recurrence rates following a block resection are considerably less than that following enucleation and curettage. A small number of recurrences in autogenous bone grafts have been reported in the literature. This report describes a recurrent ameloblastoma in an autogenous bone graft occurring 28 years following resection and reconstruction.
