Plexiform unicystic ameloblastoma-a case report and review of literature

Abstract

Ameloblastoma is categorized into four types; conventional solid (multicystic), unicystic, desmoplastic and peripheral varieties. Unicystic ameloblastoma (UA) may originate de novo as a neoplasm or from the epithelium lining of an odontogenic cyst. When UA arising from cystic epithelium reveals a plexiform pattern of epithelial proliferation without early ameloblastic changes, it is called as "plexiform unicystic ameloblastoma" (PUA). The purpose of this article is to report a case of PUA in 22-year-old male and to discuss its pathogenesis, clinical features and management. Also, an effort is made to review early literature on this entity.
