The term plexiform unicystic ameloblastoma (UA) refers to a pattern of epithelial proliferation that has been described in the cystic cavity. Due to the unilocular presentation, it is commonly misdiagnosed with an odontogenic (dentigerous) cyst. However, they may often behave clinically as biologically aggressive tumors. The location of the UA within the jawbones shows a marked predominance of the mandible irrespective of the variant. The posterior mandible, including the ascending ramus, is the region most often affected in both variants. In the present case too, the ramus was primarily involved. These tumors show a high incidence of cortical perforation, tooth resorption, and a high rate of recurrence after simple enucleation. Hence need to be carried out of segmental resection due to the extensive size of the lesion. This case report aims to provide an insight into this biologically and radiographically distinct entity. An accurate and timely diagnosis of the character and extent of UA should be done which is only possible after a thorough microscopic examination of the lesion. A literature review on the topic has been added along with a case report highlighting the approach of diagnosis and management of such ameloblastomas.
