Most ameloblastomas contain microcysts but the unicystic variant has a lining of flattened tumour cells which resemble those of non-neoplastic cysts, with nodular proliferation into the lumen without infiltration of tumour cells into the connective tissue wall. Over 80% of these cystic tumours enclose the crown of a tooth and mimic dentigerous cysts radiographically. We have reported five cases of two different variants of unicystic ameloblastoma and also highlighted their clinical, radiological and histological features.
