Plexiform unicystic ameloblastoma: a case report and data analysis in the Indian population.

Unicystic ameloblastoma (UA) among the different types of ameloblastomas is least encountered. The reason for lack of perception is paucity of case reports published in the literature. The UA, first described by Robinson and Martinez in 1977, is relatively a rare type of ameloblastoma accounting for about 10-15 % of all ameloblastomas. The term, plexiform UA, refers to a pattern of one or more nodules of ameloblasts like cells projecting from the cystic lining into the lumen of the cyst. Here we present a case of swelling in the anterior mandible of a 25 year old male which on histological examination revealed plexiform UA, which was later treated by complete surgical excision. A tabular data analysis of the previous UAs occurring in the Indian population according to the cases reported by Pubmed has also been included.
