Diagnosis and treatment ofthe unicystic ameloblastoma

Two cases of unicystic ameloblastoma are presented. The lesions were pain-free and expanded the mandible. They were removed by curretage. Recurrent lesions had similar clinical appearances and histo­ logical pictures compared to the original lesions. The unicystic ameloblast­ oma manifested itself as a cystic cavity without solid neoplastic features, which d iffers from the solid ameloblastoma with regard to the age of the patients and the rate of recurrence. The behavior of the unicystic ameloblastoma was similar to that of the primordial cyst. Despite the obvious risk of recurrence, conservative treatment with enucleation and curretage seemed to be justified in preference to mutilating radical surgery,
