A unicystic ameloblastoma mimicking a 'globulo-maxillary' cyst: a case report.

A rare case of unicystic ameloblastoma is reported, which clinically mimicked a 'globulo-maxillary' cyst. The cyst wall was lined by stratified squamous epithelium with scattered mucous cells. In one area a nodule of ameloblastic proliferation was present. The lesion was removed conservatively and there were no signs of recurrence after a 2-year follow-up period.
